Scops owls deliver little insectivorous snakes alive to their nest, where the snakes (probably) eat ectoparasites, improving the success of the chicks!

Thanks for inviting me to see your cool experiments @gloriamurari.bsky.social. Lots of fun despite the rain and 5 trillion mosquitoes
The most amazing parents a bird can ask for. Another field season is done - another year of watching flycatchers working endlessly to give these angry fluffballs as much care as possible 🤍🖤 thank you @deryktolman.bsky.social for the beautiful pictures!

Pigments concentrations don't strictly predict color in a host-mimetic brood parasite eggshell system: royalsocietypublishing.org/doi/epdf/10....
Pigment concentrations only partially predict avian eggshell colour mimicry in a polymorphic host–brood parasite system | Biology Letters
The precise mimicry of host eggshell colours and patterns by some obligate avian brood parasites provides a powerful study system for understanding co-evolutionary arms races. However, most attention has focused on host behaviour in response to mimicry, ...

Ecological contexts shape sexual selection on male color morphs in wood tiger moths
Abstract. Color polymorphisms in natural populations often reflect the interplay between various selective pressures, such as natural and sexual selection.

I haven't seen any starter packs made for behavioral ecology yet, so I decided to create one!
If you are a behavioral ecologist (any career stage), please reply so I can add you to the list so we can more easily find each other.
