30 July

The evening was relatively quiet, which might have something to do with the unseen visitor whose steps were clearly heard between 22:56 and 22:59.

Earlier, a nightjar made a few whistling calls between 22:29:28 and 22:30:54 (the last two of those calls, at 22:30:45 and 22:30:54 were made quite close to the microphone). A couple of brief churrs are audible at 22:31:12 and 22:34:34. A woodcock contributes a little croaking at 22:48:25.

Having listened to a few random portions of the morning soundtrack, I can definitely report vigorous whistling by a nightjar at 03:03-03:04, and then all manner of noises (including simultaneous calls) produced - on and off - by nightjars between 04:15 and 04:30. The noises at 04:29-04:30 include whistling, croaking, and churring.

31 July

There is a brief but clear churr at 22:28:45. Half a minute later, several whistles are heard (over a 30-second period). Then, beginning roughly at 22:30:10, there is more churring, whistling and churring again. Things go quiet for over a minute, before another brief spell of whistling and churring is launched at 22:33:25. :sleep:

23:15 Woodcock playing

Well, on 07-24 there was an intense playing by two nightjars 03:19-04:13, at 03:56 and 04:11 it sounds like they are fighting with their wings!

(been trying to upload a recording without any luck..grrrr, but thankfully there is a backup..)

Edit: on 07-24 also callings by Green Sandpiper 0:49 and Wood Sandpiper 0:58.

1 August

:hi: Fleur, :hi: sigge

After something of a half-hearted one-minute cam search at 7:47:50, another, more thorough search (under way since 10:05:40) is being made as I begin to write this message.

As expected, no nightjars are uncovered and the search is over at 10:07:57. We are now back to a view familiar from previous weeks, the cam is back in the position from which a visiting fox was filmed a month or so ago.

A bird of prey, a buzzard perhaps, keeps calling e.g. at 10:12-10:13. A representative of another species (a corvid?) keeps "talking back" until it prevails completely and is heard to the exclusion of any other birds at e.g. 10:15-10:16.

Let's all have a good day!

A suggestion: could it be possible to move this webcam little bit out to the shore?
Lots of migrating wader birds have been reported lately from Hiiumaa :whistling:

That was an eventful morning (sound-wise at least):

03:57:25 a churr
03:58:56 a churr
03:59:07 woodcock twitting, then croaking
churring continues in brief bouts
04:00:08 a whistle
04:00:30 another whistle
04:00:48 and another whistle
04:05:00 whistling (possibly), followed by a little churring (possibly)
04:07:24 a woodcock croaking
04:08:40 a clear (though brief) churr
04:09:20 a few clear whistles to the tune of more distant churring
04:09:47 a churring call relatively close to the microphone, followed by several similar calls over the next 90 seconds or so
04:11:50 another churring call (14")
04:12:20 here comes the woodcock again
04:12:36 a churring call (6")
04:13:20 churring (several calls), punctuated by a couple of whistles)
04:15:25 more churring (14")
04:15:45 more of the same, whistling, churring
04:16:25 (at least) two nightjars whistling; then one starts churring while the other (or: another) keeps whistling - this goes on until 04:17:15, then resumes at 04:17:25 - I seem to discern two birds churring and another one whistling (a total of three(?)) - this could be worth another listen
04:18:28 a few more whistles close to the microphone
04:18:45 the same again, but this time another nightjar keeps churring simultaneously further away from the mic
04:20:30 churring; this continues for at least a minute, the sound is difficult to pick up due to its source being located quite a long way away from the mic
04:23:30 multiple whistling calls, a little closer to the microphone just past 04:24:00
04:24:17 a bit of churring, a few more whistles, then more churring until 04:25:30
04:26:01 a couple of loud whistles
from 04:26:40 a few whistles (?) and definitely some churring in the distance until about 04:28:00
04:32:11 two whistling calls
04:33:20 a series of just under 10 whistling calls quite close to the microphone, then a bit of what could be the croaking/growling sound made by nightjars as they regather in the morning
04:34:24 one more whistle
04:35:12 two more whistles

Well, well, these nights do keep getting longer.

2 August

03:21:20 whistle + churr
03:22:40 churr
03:24:00 more than ten whistling calls are heard over 60 seconds with each successive series of calls coming from a greater distance
03:25:40 a few whistles
03:27:50 an odd whistle or two
from 03:28:15 churring can just about be made out
03:29:35 a whistle (?)
03:31:10 a few whistles
03:37:40 a whistle or two
03:44:15 a few whistles, getting louder around 03:44:30, then receding again (thus, with pauses, till 03:46:20)
03:47:20 more of the same with some churring from around 03:47:50 till 03:50:30
03:51:30 a series of whistles close to the mic; then a churr in the distance
03:53:55 an isolated whistle
03:54:40 churring, with pauses and mostly away from the mic, until 03:59:40
04:00:00 the cam switches to day mode, i.e. the screen goes completely dark :laugh:
04:01:20 a series of whistles
04:01:40 at least two different nightjars whistling, a nightjar turns to churring at 04:02:10; around 04:02:20 there are two nightjars whistling and one churring (all at the same time); then churring continues, with whistling calls punctuating the churr at irregular intervals until 04:04:00
04:04:30 two clear whistles followed by a few more in the distance
04:05:15 churring, away from the mic
04:06:10 more of the same
04:06:50 a whistle (?)
04:07:05 churring, away from the mic
04:07:35 churring, away from the mic, with a few whistling calls in the background
04:12:00 a whistle
04:12:45 churring, possible followed by a whistle or two
04:14:25 a whistle (?) and a few more in the distance (?) over the next 50 seconds or so
04:18:10 possibly a few whistles (?)
04:18:50 definitely a whistle, followed by some churring
04:19:15 a whistle stands out against the background of churring; the churring goes on till 04:20:20, as soon as it ends, a whistle is heard
04:20:45 more churring (on and on, with an occasional whistle trying to break its contunuity) until 04:23:10
04:23:45 churring, with minor pauses
04:25:40 whistling, but churring continues in the background, then it's back to churring only
04:27:50 a few very clear whistles with churring still in the background
04:28:20 the churring becomes a little clearer now; the song continues, with several pauses of up to 12 seconds and several whistles cutting in occasionally, until 04:31:15
04:31:30 a whistle or two
04:31:50 more churring with whistling before, after and in between
04:32:30 a few clear whistles - is it bed time for the nightjars?
04:32:55 not yet: a few more calls are whistled
04:33:30 more churring
04:33:50 a whistle
04:34:00 more churring
04:34:35 churring (increasing intensity, initially at least)
04:36:35 loud churring (with cranes calling in the distance)
04:38:15 two whistles, followed by a churr and more whistles (away from the mic) till 04:38:35
04:39:00 a possible churr, with a wood pigeon joining the fray
04:39:32 a whistle (or two?)

And it sounds as though it's NIGHT OVER for the NJs.

A curious start to the night shift - another new (?) visitor is heard.

First, there's a bit of whistling at 22:38:20, superseded by churring at 22:38:50. As the churring continues (with pauses), a very clear hoot is sounded at 22:40:53 - an eagle owl seems the likeliest source. Subsequent loud hoots are heard at 22:41:06, :17, :26, :34, :43, and :50. Another series of hoots (with the source a little further away now) begins at 22:42:11. More hoots come at 22:42:16, :22, :28, :34, :40, :48, :56, 43:04, :14, :22, :28, :35, :44 and :52, while at 22:43:10 a nightjar joins in, whistling. By 22:44 the eagle owl has gone quiet.

:hi:

Thank you Marbzy for your report. :thumbs:
Great sound from the Eagle Owl.
I had also listened for a while, but that was when the night lights were not on yet around 23:00 Then the owl was of course gone again.

:hi:

Thanks, Fleur, for your observations. I can just confirm that our nightjars are still around, allowing themselves to be heard, but not sighted.

Below are (most of) the nightjar-made sounds picked up by the camera mic between 22:20 and 22:50.
22:20:27 a whistle
22:22:27 3 whistles and a churr
23:23:22 2 whistles
23:24:27 3 whistles
22:31:55 2 or 3 whistles followed by some churring
23:32:57 a whistle
22:33:35 a long series of whistles and possibly some churring, all drowned in the noise of a passing vehicle
22:34:57 4 whistles
22:35:20 a series of churrs, continues till 22:37:00
22:37:18 more whistling
22:39:00 more whistling
22:41:48 churring

22:18:17 a wake-up whistle!
22:18:50 and another!

Good night to all...

Now, wait a second! 22:25:27 we've got a visitor on the far side of the ditch - it's got to be a young roe deer, hasn't it? The four-legged visitor climbs down into the ditch and then strolls out of cam view to the right at 22:26:13. Is he going to come back?

PS I tried to upload a video of the incident, but the file downloaded from the archive wouldn't play correctly in my vlc. Better luck anyone?

:hi: Fleur!

The roe deer was really pure chance. I can't help wondering how many visitors have been missed...

As for the nightjars, they had a relatively quiet morning, but this may be put down to the fact that I had to cut my listening session, skipping the part between 03:52 and 04:24. Overall, there was a fair amount of whistling between 02:51:39 and 03:52:02. A few notable series can be heard at:
- 03:07:44 whistling (a series of whistles across a 35-second period)
- 03:22:28 a series of whistles till 03:23:10
- 03:41:21 a series of whistles
And then at 03:42:00 there is a bit of croaking, which sounds like two birds quarrelling

[...]

Then there a few more sounds past 04:24:00, including:
- 04:24:28 whistling (continues, with pauses, for over a minute)
- 04:31:40 churring (rather rarely heard this morning)
- 04:32:38 two clear whistles and a brief churr
- 04:33:11 a couple of loud whistles
- 04:35:25 croaking at dawn? - this series of sounds brings to mind an irritated hen scolding her chicks for fooling around (or maybe just a fieldfare?)
- 04:40:27 three whistles
- 04:40:57 a single whistle
- 04:41:08 four whistles
- 04:41:18 (seems like) the final whistle

Till next time!
