Dear all,
I am visualising videos from our great tit-nestboxes (nests were recorded when the chicks were 9-10 days old, hatching date = 1) and I figured out that, sometimes, one of the parents remained inside the nestbox and foraged the chicks, while the other one brought the prey items to the nest (without accessing the nestbox). Due to a ringed bird in a couple, I could confirm that the bird inside the nestbox was the female (as expected). However, I need stronger evidence about it at this stage: does anyone have any paper to suggest about this specific behaviour when chicks are 9-10 days old? Something proved by using PIT tags and cameras, for example?
Thanks a lot in advance!
Krzysztof Deoniziak thanks a lot for your reply, I will contact him for sure!
All the very best,
Michela
Dear Dr. Michela Corsini ,
Here is useful article about Male sexual attractiveness and parental effort in Blue Tits: a test of the differential allocation hypothesis:
Article Male sexual attractiveness and parental effort in Blue Tits:...
Evolutionary conflicts of interest between family members are expected to influence patterns of parental investment. In altricial birds, despite providing the same kind of parental care, patterns of investment in different offspring can differ between parents, a situation termed parentally biased favoritism. Previous explanations for parentally biased favoritism have received mixed theoretical and empirical support.
