12:44 - Nori decides that being on the right isn't the best spot to get food, gets up, takes a poo, and moves towards the middle, squeezing himself between the other two chicks. Smart move because Elo was satisfied and Nori now receives food.

13:00 - Feeding is done. After Piret picked up some spoiled pieces of fish and fed them to Nori, and also took a few bites herself, she moves some twigs and then flies off to the camera stand. Meanwhile the sun started to shine again in Kalakotkasland.

13:13 Piret brought some new twigs and found a small ? in the nest. Whatever it was, she ate it
13:16 She left the nest

12:12 Are those Piret's tail feathers?

I think that´s a wing tip in your picture from 12:12, Lizitas.

Thank you very much for the beautiful pictures. I watch the family. It is too bad there is no chat, but really I am not complaining. To watch these beautiful babies is wonderful. thank you.

@ Kukelke: Thank you for your pictures and the information about the feeding at 12:44. Very informative! :2thumbsup:

I noticed that every now and then the chicks move their head from side to side, a bit like owls tend to do. :dunno:

I know that owls do that in order to determine the distance to something they see, because owls have their eyes 'locked' in the sockets (their eyes can't move, hence they have to move their whole head), and also because owls often hunt and fly by hearing, and their facial disc helps them with that.

Could it be that our chicks make these owl-like side to side moves with their heads for the same reason, as if they try to determine the distance and maybe speed and such of the object they're looking at?

Btw, 13:40 - Piret on the nest again, busy with re-arranging twigs and branches. Lil' Nori is eager to help mum.

Hi Kukelke :wave:

I have seen that too, it reminds me a bit of Stevie Wonder :laugh:

I have found at a German page, that all birds need to move their heads for better hearing , beacuse they don't have external ears . Maybe the chicks explore this yet and move their heads a bit more than normally the adults do? :puzzled:

Hello!

Thank you for the great pics and videos! I have been on vacation and could not see the ringing, so I am very happy, that I can watch it here, yay :loveshower:

.
The birdies are soooo big :shock:

and I have noticed, that they got names meanwhile. I am curious what gender they got.

I have never heard this about determine distances by these movements, but it sounds reasonable -then thanks for this information.
But not only by Ospreys it is seen, also the WTEs and other raptors I know are seen doing these movements. At the danish raptor, Common Kestrel, it is very distinct to see amoung both adults and youngs

Thanks, maertha. Later I noticed that Piret's tailfeathers aren't that long. :puzzled:

But it looked funny anyway.

You're welcome :)

At first I thought that Nori had given up to receive food this round when he got up and pulled out, but Nori is maybe in the process of developing new tactics to get his share of the food?

I've witnessed something similar when watching a nest of 3 barn owlets, where the youngest was pushed about by his older siblings (without pecking btw), so he was hungry all the time while the other 2 were well-fed. After a couple of days he developed new tactics to get his share of the food... by lowering his head to the ground as if he was a vacuumcleaner, and then trying to sneak up from behind, get his head under the wings of his siblings who were eating, steal their prey, and then swallow it very fast before the sibling had time to react. (Is the owlet in my avatar btw)

When they put the rings on the chicks did they also specify the gender of the chicks? Does anybody know it?

I've found something interesting about hearing of birds

Quote:

The ear evolved in fish as an organ of balance and it still performs this function today in both birds and mammals. The part of the ear that is the organ of balance consists of three semicircular canals situated in a part of the inner ear called the utriculus. These three canals lie one each in the three different planes of the material, i.e. one horizontal, one vertical and one sagittal. They contain a fluid and sensitive hairs. Movement of the head causes the fluid in the canals to move which energises or triggers the sensory hairs. The degree of movement of liquid in each canal combines to tell the bird exactly where its head is at any given moment in time. This is very similar to how the human sense of balance works. Naturally, for creatures who move in a fundamentally more fully three dimensional universe than we do a good sense of balance is very important.
