brood reduction by female at 17:32

fly high little No6 !

she hadn't food - offered the little ones body (they do that when food isn't available )

[Adria]

18.19.- the female decided to eliminate the number 6 a and at 18.21.36 she ate it


she wasn't hungry, she had good PS, so why? Poor little one, bye , bye

[Adria]

18.25., 18.37 - The female refuted the chick and served it to the chicks .:


just today I wanted to suggest whether the female should be given another name, as 99.9 percent is not Janika.

[Adria]

19.08.29 - Jan arrived and at 19.08.39 A female flew away

[Adria]

19.09. Jan feeds -four chicks ate, the fifth came late, bur...


at 19.11.38 - number 5 finally got there and ate something



Can storks count? I wonder if Jan knows he has one chick less .

[Adria]

20.09 - Jan cleans and massages the chicks .
22.19 - Jan cleans and massages the chicks .
23.50 - Jan cleans and massages the chicks .

Hello everyone

blog post to brood reduction in Karula nest in 2017 season by Tuul Sepp (commented also by Urmas)
"It could have been a decision of vital importance, to grant the survival of the remaining three fluffy-balls."

and two scientific (but "old" because there are very much white and some black stork cameras where we see brood reduction enough often)
