12:10 PM @MKmatylda​​
12:09 both in the nest

12:13 PM @Светлана-ни​​
12.04 - что с крылом у Зики? /what is with Z. wings?

1:17 PM @паніСвітланаК​​
13:17 вилетіли з гнізда / out

2:16 PM @паніСвітланаК​​
ак цікаво спостерігати за самцем як він приніс гілочку з листочками 9:36 і мостить її, приміряє куди покласти / It’s so interesting to watch the male — how he brought a twig with leaves at 9:36 and is arranging it, trying out where to place it

2:40 PM @паніСвітланаК​​
14:29 прилетіла Зіка / Z. back

3:25 PM @Vida-LI​​
Buenas tardes. Nueve años observando nidos y las cosas que están pasando este año en diferentes nidos, me parecen increíbles.
3:25 PM@Vida-LI​​
13:03:57 ¡¡Zica pisa el cuello doblado hacia atrás de Natalio tumbado!! No sé qué pretendía / Se ve por fotogramas en el ordenador, en un móvil no sé si puede verse.

Good afternoon. After nine years of observing nests, the things happening this year in different nests seem incredible to me. Zica is stepping on Natalio’s neck, bent backwards, while he is lying down! I don’t know what she intended. You can see it in the computer frame‑by‑frame view; on a mobile phone I’m not sure if it’s visible.

3:31 PM @паніСвітланаК​​
15:30 самка полетіла з гнізда /female out

@marikamarika8276
@Vida-LI Hi Vida, it’s rare, but we do sometimes see this kind of behaviour on black stork nests. However, I know only our Zica who does this towards her own offspring.
5:09 PM @marikamarika8276
Dr. Strazds: „Females sit on males” is a form of reversed mating.
5:02 PM@Светлана-ни
marika, так делала Тоничка в Макове, есть видео. Вам прислать ссылку? / marika, Tonicka did this in Makov, there is a video. Should I send you a link?
5:19 PM @marikamarika8276
​​@Светлана-ни sorry, yes - this is also true

5:39 PM @паніСвітланаК​​
