7:56 she is aerating the nest bowl (birds are pretty loud! )please little birds! be quiet for a moment!


8:44 egg rolling

[Liz01]

9:40 Jan came home for a short visit.


greetings

[Liz01]

and off again. That was a short visit. No idea why he came. It could be that a unwanted guest was nearby


10:02 Janika stands up, is preening herself


10:06 she is aerating the nest bowl


10:06:55 ps to the left - she rearranged the branches and the moss
10:08 she settles down . the egg is saying nothing these beautiful singing birds are great! But every now and then they should be silent

[Liz01]

10:54 Janika is aerating the nest bowl. A wren is singing nicely and pretty loud. Other birds are singing too

11:09 Jan came home again with a small bunch moss. Both are singing
He takes care for the eggs. Janika flew away!
She will collect very small fishes for very small little storklets

[Liz01]

11:13 Jan stands up and turns. I saw a egg pile
11:13 up again and down on the eggs
11:14 up
11:29 Janika brings moss

[Liz01]

11:33


11:50 he stands up, shakes his plumage and is aerating the nest bowl
11:53 he is aerating the nest bowl again
12:30 Jan is aerating the nest bowl and turns the eggs

[Liz01]

13:01 Jan is looking to the left and up!




he is looking to the left again
13:07 he stands up, is starts preening himself.
13:08 poking in the nest bowl, PS to the left, shaking his plumage and takes care for eggs and nest bowl. I hear no egg talk!
the environmental noise are too loud? there is loud humming all the time. I think the microphone catches the wind noise. Nest noises can hardly be heard. I can not hear the poking in the nest bowl this is usually a loud noise

[Liz01]

13:44 egg rolling
13:47 short aerating
14:13 Jan is aerating the nest bowl
14:15 aerating and turning the eggs


14:29 aerating

14:46 someone interesting in his sight
14:55 he is aerating the nest bowl and turns the eggs


all birds turn their eggs because it’s required for the embryos’ survival. For instance:

The temperature in the middle of a clutch is warmer than the edge. Birds move the outer eggs to the middle to keep them evenly heated.
In the early days of incubation, it’s important that the embryo floats inside the egg while the membranes that support its life are growing and developing. Turning optimizes membrane growth.
Eventually the chorion and allantoic membranes will be pressed to each other and to the shell. If these membranes adhere too soon the chick will not be able to move into the hatching position later and get out of the egg. Turning prevents premature adhesion.
The albumen (the egg white) is the embryo’s fluid cushion and water supply. Turning the egg optimizes the fluid dynamics of the albumen so the chick can absorb it properly.

if someone is interested: New technology offers insight into egg-turning behavior.

15:15 Jan stands up , is aerating the nest bowl and turns the eggs
15:16 done!
15:20 up again... and settles down. what is wrong? for it looks not normal?

16:12 he is preening himself






16:16 settles on the eggs again

[Liz01]

16:18 up again and down again
16:22 aerating and egg turning

I have the impression that it is ventilated and turned far too often. Actually, the rhythm should be about every hour ?
I have to ask aunt google

answer-
Eggs must be turned at least 4-6 times daily . the last three days before hatching it is not necessary. The embryos are moving into hatching position and need no turning.

this is interesting too:
https://ornithology.com/ornithology-lec ... ent-birds/
Incubation is defined as adding heat to the eggs. Most birds, except ratites, pelicans and relatives, and waterfowl, develop brood patches (featherless areas) in the ventral abdominal wall just before incubation. The brood patch becomes very infused with blood vessels and sensitive to temperature. The incubation period is the time between the laying of the last egg in a clutch and the hatching of that egg – except that birds can sit on eggs without adding heat to them- the brood patch must be applied to the eggs. In about 54% of all bird families, both sexes incubate; in 25% only the female does so, in 6% only the male, in 15% by either, and in one family (brush turkey) none.

[Liz01]

16:56 He stands up and is aerating the nest bowl. 1 egg is moved. I think I hear egg talk.
