What's happening in the stork nest
Karula's stork's nest got a foster child, whom LK forum members aptly named Bonus.
Why didn't we write a story immediately after ringing, measuring, weighing the nestlings and leaving the foster child in the nest?
Urmas and Ain, members of Kotkaklubi, visited the nest (he took care of recording the data below and the delivery of supplies).
An immediate review does not give a picture until the old birds have visited the nest to get to know the situation. Do they accept the foster son and what is their attitude and behavior? Any such undertaking may contain unimaginable and random dangers that even the most experienced ornithologists cannot foresee.
Urmas was at the nest for a little over an hour. The nestlings vocalized restlessly in relation to the disturber, but Urmas covered them with a jacket, which reminded the storks of the covering by the old birds a few weeks ago, and the young birds calmed down.
All three got rings, with the longest ten-centimeter beak was the largest stork, which weighed about 2.4 kg. The weight of the little one remained about half a kilo smaller. Although foster child Boonus is a week older and looks bigger, his weight is only one hundred grams more than the bigger nestling.
But let's look at the morning's events.
Everything is new for Bonus, who spent 24 days in the clinic: a trip to the unknown, new nestmates, sounds of the forest, and of course adaptation takes time. So we too can observe something completely new.
The female Kaia arrived at the nest at half past nine. The stepson Boonus received the female bird with a defensive attitude like an intruder. There is nothing surprising, because in the clinic they had a motionless "stork figure" next to the nest, and the image of the old bird as a feeder may have been forgotten. During the first flight, Kaia fed the nestlings and after a while brought a branch to the nest and later a wet straw for the nestlings to reduce the water requirement of the nestlings in the heat. The female bird has taken care of the so-called drink during the entire heat wave, but the stepchild's attitude was repulsive even then. Did the female bird carefully study the change in the increased litter, or is it just our human nature to think?
The young nestmates seem to have recognized Bonus - at least in some part because his behavior is slightly different.
The male bird Karl arrived at the nest a few minutes before ten and the female bird Kaia left.
Karl fed the storks and there is no time to calculate because the family wants to be fed.
In any case, interesting nesting times. We can only keep our fingers crossed for success.
Uh.. pagaidām viss labi
