White-tailed sea eagles in Latvia: Juras-Erglis 2021


A new topic for the new year! :laugh:
Image

The beginning season is direct continuation to the previous season as the camera has been working with a few breaks. You may catch up where we came from here:
https://www.looduskalender.ee/forum/vie ... tart=15600


Camera links

The video transmission from the nest is streaming in Youtube, presently
(starting from 26th Nov 2020)
https://www.youtube.com/watch?v=xQu9kZeQtZ0
If the address should change for some reason, I'll keep the old addresses here in case someone would need then later.)

The address of the Youtube may sometimes change. If this should happen the new address can be found by making a search 'juras erglis webcamera' in the Youtube. The link to the WTE camera, as well as the other the live cameras of Latvia's Nature Fund LDF (Latvijas dabas fonds), can also be found here:
https://www.youtube.com/channel/UCIcQwg ... hMBclDJENw
The WTE camera is not on the top of the list so you need to scroll down a little. In Latvian it is called "LDF Jūras ērglis tiešraide".
We'll try to remember to update the address here if it changes. If you have trouble finding the camera please let us know (write to ame or Liz01) and we'll try to help.

The Youtube stream can be scrolled back in time 12 hours from present. This way it is possible to see what happened at the nest during the previous 12 hours. This makes it also possible to record the delayed stream with some screen recording program. From the Settings-button in the lower right corner one can adjust the resolution of the picture. For recordings it's best to use as high resolution as possible.

The stream can also be viewed (for example) on Potplayer or with VLC player by opening the same address as for YouTube. Potplayer can also be used for recording the Youtube stream and for taking snapshots from the stream either live or from recorded video. Potplayer can also record delayed stream from screen. VLC can take screen snapshots but not record the stream (or at least i can't make it happen).
The overall use of Potplayer is discussed here:
https://www.looduskalender.ee/forum/vie ... 50#p499450
The use of VLC player is discussed here:
https://www.looduskalender.ee/forum/vie ... ?f=3&t=739

There are also several other screen recording programs which can be used for recording the stream. The use of some of them are also discussed in the Questions and help-topic:
https://www.looduskalender.ee/forum/vie ... ?f=3&t=770


Working hours of the camera

Normally this camera is operating 24/7, thanks to the installation of a methanol fuel cell power system in Autumn 2017. The fuel cell provides power to the camera system when the solar cells will not get enough sunlight to feed the batteries.
Presently (winter 2020 - 2021) the camera has some power problems and the stream is switched off for the night time. In the darkest time of the winter the camera working hours have been 7:30 - 17:30.

Sometimes there may be a malfunction in the streaming system. If refreshing of the Youtube-window or reopening/restarting of Potplayer (or restarting your pc or router in extreme cases) will not help, please report either ame or Liz01 and we'll try to look for help. I have noted that Potplayer will record no more than 6 hours of continuous stream at one go. Then it will stop. This can be overcome by restarting a new Potplayer before the time limit of 6 hours. Nothing guarantees, however, that Potplayer will record the full 6 hours. It may stop at any time without any clear reason.

The camera time is the local, Eastern European Time EET which is 2 hours ahead of GMT (or Greenwich/London time), and one hour ahead of the Central European Time CET. In summertime the daylight saving time adds one more hour to GMT.
Overseas viewers please note: if you see a black screen check if you can see the time stamp in the lower left corner with the clock running. It may be night time in Latvia and then the camera shows darkness. :sleep:

The camera clock normally runs somewhat delayed compared to the 'real' time (your computer time). This delay is quite normal and may vary from time to time from a few seconds to even some minutes. The delay is due to the data transmission chain and its efficiency, and it mainly depends on the speed of each viewer's own internet connection. Therefore it is important that the camera time is given when events at the nest are reported, because the camera time is 'the real time' for the nest. It's also strongly recommended that the camera's date&time stamp is not removed from any pictures that are posted. Without the time stamp the picture will only have an artistic value (which is naturally not overlooked! but it will not be useful for ornithologists).

Important events at the nest
searchword searchnestsummary

Events will be added to this list as times goes on and interesting and important events take place.
  • March 24 Milda saw something that made her leave the nest in a hurry at 11:45. Raimis returned at 13:11. The eggs were uncovered for 1 h 26 min.
    viewtopic.php?p=783848#p783848
  • March 27 at 19:26 Raimis flew out after the evening shift change with Milda. He was never to be seen after that. Apparently he either died soon or got so badly injured that he could not return. (update Apr 17).
    viewtopic.php?p=784555#p784555
  • A restless period of two weeks followed, with a few strange male eagles in turns frequently visiting Milda. Milda stayed on the nest, taking care of the eggs.
    April 3rd in the afternoon, for the first time in two weeks after Raimis had disappeared, Milda flew out a few times, but returned soon after every outing.
    viewtopic.php?p=786441#p786441
  • April 7 at 6:47 a stranger with a peculiar voice flew to the top of the nest tree. The voice of this male was quite different from the voices of strangers that were heard near the nest after Raimis disappeared. The voice is a high-pitch chip-chip-chip, like a little bird's cheep. Later the male with this voice was called Mr C (or Chip or Chips in the YT chat and DDF).
    viewtopic.php?p=787525#p787525
    The male with the special voice returned in the evening at 20:04. Between these visits a male or males with normal voices visited Milda.
    viewtopic.php?p=787826#p787826
    In the late evening a stranger flew to the nest tree. he had a normal male's voice. At 21:19 Mr C called in the forest and the stranger on the branch replied.
  • Apr 8 early in the dark fights took place near and on the nest. The fights continued till about 7:40.
    viewtopic.php?p=787891#p787891
    The restlessness continued after 11 am far in the forest. During these fights Mr C was apparently able to banish the other male.
  • Apr 11 at 6:45 Mr C rolled the eggs.
    viewtopic.php?p=788918#p788918
    Later the same morning Mr C brought several green spruce twigs to the nest.
    viewtopic.php?p=788945#p788945
    In the following days he continued bringing more nest material and from now on Chips gradually assumed the role of the father at the nest.
  • Apr 23 at 12:11 a pip hole was visible in both remaining eggs. In the darker egg the hole was big. Loud egg talk was audible.
    viewtopic.php?p=793194#p793194
  • Apr 24 The second chick hatched during the night and was seen for the first time at 5:39.
    viewtopic.php?p=793445#p793445
    Egg talk was possibly heard from the third egg, too, but it's always difficult to know for sure with loud-cheeping hatchlings "onboard".
    13:35 Chips brought a crow.
    viewtopic.php?p=793615#p793615
  • Apr 25 The third egg was still whole.
    13:05 A strange eagle flew by the nest and caused an alarm at the nest. Chips stole the crow. Milda ate the fish which was the last remaining food on the nest.
  • Apr 26 The third egg was still whole. 6:21 Milda flew to the Observation Oak and then away. The chicks and the egg were left alone. At 6:48 it began snowing.
    viewtopic.php?p=794147#p794147
    At 7:41 Chips flew to the nest but he didn't cover the chicks and the egg.
    8:54 Chips flew out. The chicks hadn't moved any more since 8:30.
    8:56 Milda flew to the top.
    9:05 Milda took the dead chicks and began to pluck them. Finally she ate the chicks and then flew out. Later in the afternoon she returned and stayed on the egg for three hours in the early evening but flew out for the night. After that Chips returned and stayed on the egg for the night.
  • Apr 27 At 6:28 Chips flew out after a night shift of incubating.
    viewtopic.php?p=794513#p794513
    6:33 -6:47 Milda visited the top of the spruce on the right. After that Milda and Chips were heard calling in the forest every now and then till 12:59. Then followed a period of more than 5 hours with no eagle voices being heard.
    18:23 Chips called and flew in.
    viewtopic.php?p=794719#p794719
    He was looking around in the forest and in the sky and called rather a lot. At 18:44 he flew away and called outside.
    20:35 a strange male flew in.
    viewtopic.php?p=794772#p794772
    He took up the egg and crushed the shell and ate the content.
    20:41 he called with a normal male's voice when Milda flew to the top. Milda cried and the stranger called.
    20:44 the stranger flew out. Later we began calling this stranger Mr L (Mr K or K Kungs in the Dabasdati forum).
    After this the three eagles, Milda, Chips and the new stranger, Mr L flew in and out in turns and called both on the nest and out in the forest till late in the evening.
  • Apr 28 The three eagles called in the moonlight in the forest many times during the night. During the day Chips and Milda were heard calling many times in the forest and Chips visited the nest many times.
  • Apr 29 The three eagles called in the forest many times from early morning till the evening. Chips visited the nest a few times. In the evening a strange male (Mr L) visited the nest. His left leg was injured. He made some nest work and lay on the nest for a while.
  • Apr 30 In the early morning both Mr L with his injured bloody left leg and Chips with a drooping wing visited the nest in turns. Apparently the wing was injured, too.
    7:35 Chips pooped on the nest and then flew away. He was never seen or heard anymore.
  • May 1 and 2 In the nights and early mornings two eagles visited the nest in the darkness. They were a male with normal voice and a female. Mr L visited the nest a few times at daylight either in the morning or the evenings. At daytimes both were absent but some voices were heard.
  • May 3 Mr L visited in the early morning and later nearer to noon with a fish which he ate.
    18:11 Mr L flew in.
    viewtopic.php?p=796745#p796745
    18:16 Milda flew in.
    19:04 they flew away together.
    from this onward Mr L became established as Milda's new companion.
Later in the autumn Mr L began to bring nest materials together with Milda and often also independently, without Milda. Mr L has also visited the nest frequently to see that everything is ok. He has brought some food to the nest and ate it without Milda noticing it but
  • Nov 2 16:06 Mr L brought a fish. 6 min later Milda flew home and took the fish from him. Mr L didn't protest in any way, but flew away. Milda ate the fish.

Introduction


Inhabitants of the nest: the female Milda and the male Raimis.
Image

Below you can read the beginning of the introduction by Jānis Ķuze for this nest camera, given for the Latvian Dabasdati forum on Dec 31 2016, written in Latvian originally for Season 2017, translated by GoogleTranslator.
I have corrected some obvious mistakes in the translation (and marked them grey in the text) and inserted the correction in parenthesis in italics after the text.
Sea eagle (Haliaeetus albicilla)

The camera's nest is in Kurzeme, Durbe County. This nesting area has only been known since 2014, when the first nest of this pair was built on a pine tree in a felling area. In 2014, the eagle couple nested very successfully - it was one of the four sea eagle nests in Latvia this year, raising three juveniles. In 2015, the eagles decided to move to a new nest and began building it on the top of an old spruce tree nearby, which was once broken by wind or snow. Several branches overgrown the fracture site, forming a suitable jaw for construction of the nest at a height of about 25 meters. The camera was placed on one of the end branches in late January - at a time when nest construction had just begun, providing a rare opportunity to observe the process of building a new nest - so far the cameras have been placed mainly on sea eagle nests for several years (several years old nests). The nest is interesting because it is built on a spruce, as the spruce sea eagles seldom choose to nest - this is only the fourth nest so far known in Latvia. About one-half of the nesting sites of sea eagles are built in pine trees, and a third in birch, black alder and oak trees. In spruces, nests are usually built directly on such broken tops and are usually high above the ground. The highest known eagle's nest in Latvia is located in the territory of Kemeri National Park 31.5 meters above the ground and is also built on spruce.

Identification of the eagles

Knowing who is who on the nest is not a problem if at least one of the inhabitants wears rings. Unfortunately neither Raimis nor Milda have rings and therefore we have to look for details in their appearance or hear their voices. In the introduction of last year's topic you will find a thorough discussion of how to separate female and male eagles in general, and what are the special markings which are useful in separating Milda and Raimis from each other. The plumages of adult eagles change slowly in the early moult. The pictures shown there are not quite fresh but a year old (or slightly more) but the eagles haven't changed too much since then.

The tail spots of eagles form individual patterns which allows identification of different eagles. Fortunately the tail patterns of Milda and Raimis are very different. Raimis has big black spots in a row and Milda has much smaller spots. The border between the white tail and dark feathers on the back of Raimis is irregular: there are dark "rays" (or "moustache") on both outer edges of the tail. The borderline between black and white on Milda's tail is smooth and regular.
Image

Raimis has two big spots which form one very big spot or a horizontal bar if the tail is folded. When he opens his tail wide the two spots on his tail may divide into three or even more spots. His spots are shaped like tulip flowers. The border between the white tail and the dark back is not clear but uneven like the cutting edge of a saw.
Image

Milda has two or sometimes three small spots in a horizontal line in her otherwise white tail when she spreads her tail wide. Sometimes the middle spot is hiding and only two spots can be seen. Sometimes her spots are united in only one spot. The borderline between her white tail and dark back is clear and smooth and regular.
Image

The tail patterns of Milda and Raimis didn't develop much at all during last two years. Both are mature adults and the patterns are fully developed. Some pictures of their tails in earlier phases can be seen in the introduction for the previous season.

For a more detailed discussion of the identification of eagles in general and, on the other hand, Milda and Raimis in particular please return to the introduction of the previous season:
https://www.looduskalender.ee/forum/vie ... 39#p704639
Please note that the pictures shown there are a year old. The patterns of fresh dark feathers and worn light feathers on the wings and backs of Milda and Raimis have probably somewhat changed during the moult after that.

albicilla found a very useful article which describes the development of the outer appearance, including plumage of WTEs with age:
http://www.nof.nu/rrk/Bestamningsartikl ... y0cSPSAG7E
The article is in Swedish (with a summary in the end in English) but there are a lot of pictures illustrating the changes.

Distinctive marks of Mr C.

In the lower mandible Mr C has a dark spot.

The tail pattern. The tail may also look surprisingly different in different positions and when the feathers are wide or folded.

The location of the nest

The location of the nest is in Durbe County near the city Liepāja in Western Latvia, marked with blue line in the maps below. The maps were provided by Jānis Ķuze.
Image

There is one big lake, Durbes ezers, with a nature reserve area. There are also other water areas in the county, both natural and artificial. There is a fish farm in Skrunda (on the right side of the map) with large ponds which are drained for harvesting the fish in autumns. Plenty of fish remain in the ponds after they are drained and the ponds lure flocks of WTEs both young and adult to feed. The fish in shallow water are easy catch for the young eaglets who are learning to fish. Thus the fish ponds can be called their "school".
Image
On 14 Feb 2015, 10:42 Jānis Ķuze wrote:this nest is located not far away from several farmsteads, that is the reason why dogs can be heard, some of the chainsaws are coming from there as well. ...
Besides dogs we have heard voices of all kinds of farm animals to the nest over the years: cows, cocks, even turkeys.

The nest site was granted a micro reserve status in October 2015. Jānis Ķuze wrote about it in Dabasdati forum on Oct 12 2015:
http://dabasdati.lv/forums/viewtopic.php?p=53464#p53464
Translated with the help of Google translator:
"We just got a message from the State Forest Service - nest is officially established microreserve! It is surrounded by a wide buffer zone in which forestry activities are not allowed during the nesting season. Thus, from the forest to disturb the work, this place is now protected."

We may get some clues about the location of the nest from what we see and hear over the camera. Based on these clues it is possible to narrow down the location of the nest in more detail. We ask every one of you to keep all detailed information, even speculations about the location to yourselves. Please also do not share any further information about the location anywhere in the internet, not in this forum nor anywhere else. More detailed information of the location of the nest may encourage some people to go and seek the nest in nature. Nest tourism like this is the last thing that is needed here in the delicate breeding time. People near the nest may frighten parents away from the nest and leave eggs or chicks unprotected from weather and predators. Thus an intrusion may lead to destruction of the clutch.
Thank you for your co-operation.

The nest and its surroundings 1/3

The nest is built in the top of a spruce which has been broken possibly in a storm many years ago. After that several side branches have started to grow as replacement tops. The biggest branch on the right of the nest in these pictures has won the race of becoming the new top. This is also the trunk which we see in the left side of the camera view.

The nest is about 25 m above the ground. The height is corrected from old texts where the figure has been 30 m. There has been a misunderstanding. See the original introduction by Jānis Ķuze:
https://forums.dabasdati.lv/viewtopic.p ... 93#p108693

The nest is described in more detail here:
http://www.looduskalender.ee/forum/view ... 03#p433903
and here:
https://www.looduskalender.ee/forum/vie ... 69#p627169

Below is a picture made of Tringa's photograph where the branches which we can see in the camera are marked. The picture was taken from the direction to which our camera looks. Thus the branches which we see in the live camera on the left are on the right side of this picture. One special branch is also shown: the "poop branch". The name came naturally since Durberta painted this branch white by shooting poop on it very often. By the end of the season 2015 it was all white. The poop branch also frames the top of our camera view. An ellipse shows the place where the camera is most probably attached to.
Image

Below is a picture of the camera attached to the tree. It is camouflaged with plastic Christmas decoration twigs.
Image

In summers 2018 and 2019 the eaglets Robis and Vilnis (2018) and Rika and Miks (2019) drew out nest sticks one by one as part of their catching exercises. In both years the nests gradually disintegrated totally. Thus we have been able to see what the foundation of the nest is. In this picture also the microphone can be seen (encircled with a yellow line) together with a visiting nutcracker (Nucifraga caryocatactes).
Image

Later in the autumns of both years the parents Milda and Raimis have rebuilt the nest so that by the change of the year the nest is almost ready for breeding. In 2020 the eaglets Malda and Reinis were more gentle with the nest than their older siblings and didn't tear it down. Milda and Raimis didn't need to begin rebuilding the nest in the autumn from "ground zero", and they have had holiday instead. They brought only few sticks to the nest during the autumn. Now they have a lot more to do than a year ago before the nest will be ready for eggs.

The nest and its surroundings 2/3

The closest trees are shown and named in the following for ease of referring to them.
In this picture below by Sonchik the closest trees in the surroundings are seen in front of the mist. The big oak on the right has been a favourite perch of the parents in the previous seasons. We have called the tree the "Observation Oak" (OO). On the right side of the picture behind the right branch of the nest tree the nearest spruce is seen (curved due to the optics of the camera). This spruce has also often served as a perch of the parents and the eaglets, especially the top of the spruce.
Sonchik wrote: July 15th, 2019, 11:46 am Image
The Parent's Oak was at a larger distance and it still looked much bigger than the remaining two oaks in the middle so it was in reality much bigger than the Two Sisters.
A = the remains of the Parents' Oak
B, C = the remaining oaks, the "Two Sisters". Behind the Sisters in the middle of them is a third oak, the Cousin (there are maybe even two or more Cousins hiding behind the Sisters). It is visible when the trees have no leaves. The branch of the nest tree which is hanging partly in front of the Sisters and the Observation Oak is called the Poop Branch since 2015 when Durbertina, the first eaglet on this nest, painted this branch white.
OO = the present Observation Oak

On May 30 2021 the sunlight was rather favourable to see individual trees in the meadow. i made a new picture showing the big trees and their names. on the right the Observation Oak which has been a favourite place for the eagles. in the centre the Two Sisters (and their Cousins behind them; they can't be seen anymore since the Sisters are dressed now). on the left there are side by side two oaks which have not have had names so far. i suggest that they'd be called the Twins. on their right side, farther than them (or smaller) is the Observation Oak 2 which is closest to the swan pond.
Image

The fish-eye optics of the camera lens makes the images curved so that the centre of the picture is stretched and the horizon becomes curved. The picture below shows the landscape like it probably is in reality. The horizon is straight and the nest level is also more or less flat and horizontal.
This photo is made by Nordri with a program which straightens images of a fish-eye lens. The trees on the ground are, however, curved and don't stand vertically.

The nest and its surroundings 3/3


On Dec 10 2020 the Sun rose at about 9:17 almost in the centre of our camera view.
Image

In the picture below is a sky map which shows the sector of sky which we can see. It is a combination of information of three different maps. The basis of the map is the sky in the morning at sunrise on Dec 10 2020 at 9:17 local time (7:17 UTC).
https://www.looduskalender.ee/forum/vie ... 44#p771444

The position of the Moon is added on Dec 8 at 0:23 local time when the Moon was near the top left corner of the camera view. In the picture below the Moon is on the left, a little north of east.
https://www.looduskalender.ee/forum/vie ... 67#p771267

The position of the Sun on Dec 7 at 13:11 local time (11:11 UTC) is added in the bottom of the picture. At this time the Sun was seen near the top right corner of our camera view.
https://www.looduskalender.ee/forum/vie ... 24#p771224

The sky map is made thinking that the viewer is lying on her/his back with the head to the north and legs to the south. Thus the west is on the right in the sky map and east is on the left. Straight lines from north to south and from east to west are drawn in the picture. These lines cross at the zenith which is the highest point in the sky above the camera. The outer edge of the map is the horizon. As one can see both the leftmost and rightmost points which are in the top corners of the camera view are very near the horizon. Due to the curvature of the horizon in the camera view the highest point which we can see in the camera is even closer to the horizon. This means that actually we can see only a very narrow strip of the sky in the camera view. The upper limit of our visual range is not marked in the picture.
Image

In the table on the picture the azimuth angle in the rightmost column is a measure of the position of the Sun and the Moon on the map, a "compass reading". -99 degrees for the Moon tells that it was 9 degrees north of east (east is azimuth -90 degrees). The azimuth angle +10 degrees of the Sun on the right tells that the Sun was 10 degrees west of south (south is azimuth 0 degrees). The full viewing angle of the camera is thus about 110 degrees The nominal viewing angle of the camera, given by the manufacturer in the specifications of the camera, is 107 degrees. The 110 degrees obtained above is well in agreement with the nominal value.

Here are two links to posts where one may see a comparison of the camera view with the sky map. (Sometimes Photobucket pictures are totally invisible. This is due to the "customer policy" of the Photobucket. )

and information in English:
https://ldf.lv/en/webcams
The live camera topics are under the title "Tiešsaistes kameras Latvijā Nature webcams in Latvia":
https://forums.dabasdati.lv/viewforum.php?f=18

The nest life on the various camera nests is followed in the Latvian Dabasdati forum (often DD forum or just DD or DDF for short like LK or LKF for Looduskalender forum):
https://forums.dabasdati.lv/viewforum.php?f=25

The WTE topics in DDF (Jūras ērglis) can be found here:
https://forums.dabasdati.lv/viewforum.php?f=27
The Durbe 2021 topic in DDF:
https://forums.dabasdati.lv/viewtopic.p ... 29#p266529

The language of the DD forum is Latvian. You can try your luck with some translator machine to communicate there. :laugh:
Most of the Latvian members understand English, too. Some of the DD members are members in LK, and vice versa.
Google Translator is not always reliable. It's sometimes badly corrupted for Latvian language (some comedians keep changing meanings of words). Therefore it is perhaps best to write your post in DDF in English adding the translation. Then the moderators can correct the translation if necessary.


Youtube chat

The events on the nest and around it in the forest are also commented in the chat on the Youtube page where the camera is streaming. The topics on the chat are less limited than in the DD forum or our LK forum. Often the comments may hover around quite other things than the nest events. :laugh:
The chat is multilingual. The chat is reset each time when you shut down your web connection. By reopening the comments from the last hour are shown. Older comments are not stored anywhere.

Frequently asked questions FAQ

There are some questions about eagles and their breeding which rise repeatedly over and again during nesting seasons. Answers to these questions are looked for and given during the season(s), but often they are difficult to find afterwards.

Therefore keywords for making searches for finding the answers are added in the posts containing answers. Below is a list of these keywords. This list will be supplemented as new keywords are found useful.
  • searcheggdevelopment for searching posts with answers concerning processes involving mating behaviour and development of eggs before and after egg-laying.
  • searchhatching for searching posts about when and how chicks hatch.
  • searchringing for searching information about ring-marking (or banding) of eaglets or other information about marking eaglets with rings or radio transmitters.
  • searchfledging for searching posts about how and when eaglets fledge.
  • searchnestsummary for searching for a short summary of the events during a nesting season.
    For the Latvian nest in Durbe the keyword is: searchnestsummaryDurbe
  • searchliterature for searching references (articles, books etc) about WTEs.
  • searchcameradelay for searching information on the delay of the camera time relative to 'real' time.
  • searchringedvisitors for searching ringed eagles or even other birds whose ring codes have been read at the nest.
Advice about how to make searches in the forum can be found in the Questions and help -topic here:

good morning and Image :laugh:

7:29 the camera started.

8:11:28 a pygmy owl's whistle from very far.
8:15:22 again, this time closer. (and far before that??)
8:18:25 a few whistles from far.
8:22:42 a blackbird woke up and called.
8:23:15 the pygmy owl again.
8:23:49 a very varied and interesting call by the pygmy owl. :D


8:29:52 the pygmy owl again.
8:30:17 another call from farther.
8:30:52 a call from near. i think there are two owls. :laugh:
(it's possible of course that there was only one owl, but he would have been busy flying back and forth. :whistling: )
it's slowly getting light.

Video of yesterday's walkers.
It turned out funny. They couldn't get through the kingfisher and turned the other way. :laugh:
They walk very fast in the forest. Like it's a sidewalk.

big bad bird the kingfisher! :rotf:

thank you for the close-up Sonchik! now i can see the two walkers much better. :thumbs:
the second animal may be a dog like Nordri wrote, but on the other hand the rhythm of the walking looked like walking on two legs rather than on four. :puzzled:
it seemed to me that he had a cap with a wide white stripe in the front.
