July 10

Buzzard camera ends transmission
We always continue hoping to see the nest inhabitants visiting the birthplace. But for buzzards the ties to the nest break at once on leaving (although certainly there may be exceptions).

But the cam is still working.

Last year this cam worked until the 12th of November although it was officially closed. We'll see. But without sound it is less interesting.

Thanks again everybody involved in the work for these buzzards (and all other birds) :loveshower: it's been a wonderful time watching the chicks growing and getting strong.

Hope to see you all next year

A very often occurring situation but usually missed is when the father delivers a prey and flies away almost immediately and mother arrives within seconds to help with the feeding or to watch if everything goes well (or to protect the young?). She often calls when she comes and as long the male is on the nest. As if she is chasing the male away.
Most of the times the parents are not seen together on the nest or only for a very short time. Literally seconds. It happens so quick that it is almost only visible in slow motion. Very easy to miss while watching the cam and little chance to see it captured in the archived pictures.
A result is also that the one who brings the food can be wrongly identified because only the second adult, the female, is noticed. Perhaps this explains questions earlier in the season where the father was or how long ago the father was seen.
It also shows that the mother is often near the nest and is observing what is going on there. Invisible to us.

Another aspect

Distribution of deliveries of food over the day in June.
Total numbers per hour (10 is between 9 and 10 o'clock)
Image

The sharp peak between 17 and 18 is mainly caused by the unusual number of deliveries during that hour on July 12 (7 worms and one vole).
In 70% of the hours with deliveries was one delivery, in 22% two, in 8% three. There were single cases of four and eight deliveries in one hour.

Although officially ended, it will stay on. The "official end" just means that there won't be updates, the link has been removed from the main page and should the transmission break, nobody will go and repair it. The camera will send pictures until later in the season, when all the birds are ringed, have fledged and left and the men from Kotkaklubi have a bit more time, somebody has time to collect the parts of the camera system which can't stay or are needed somewhere else.

Hi,
a bit late, but if here's still somebody who's interested - the news from the lab are, that this year's chicks appeared to be males.

I am always interested in facts. Thank you for the news.

Oh yes, very interested, thank you! :thumbs:
So my guess (younger = male, older = female) was 50% wrong and 50% right. :mrgreen:

It shows again how careful you must be with interpretations.
Here the measurements taken during ringing on June 6. viewtopic.php?p=474178#p474178
Remember there was almost 3 days (66 hours) difference in age. That is a lot at that age.

My guess came just from their behaviour and by the seat of my pants. Nothing scientific. :laugh:

That is what I mean. Sexing somebody on the seat of its pants is not always reliable. In the past is was easy: when it wore pants it was a male, no matter what the seat looked like. Still earlier males wore no pants but always a big club, while dragging a female to a cave. :-)
