#BroodParasitism, the exploitation of parental care, is used by diverse #animals from birds to bees and beyond! We reviewed independent origins of this strategy to investigate its #phylogenetic distribution, fascinating #behaviors, and #evolutionary consequences for #diversification.

Hello all! I am a budding behavioural ecologist focusing on birds (I don’t mind studying other vertebrates tho!). I recently worked on #BlueTit aggressiveness and my next project will be with the #SeychellesWarbler. My interest lies in bird breeding behaviour, but #CooperativeBreeding and #BroodParasitism intrigue me the most!
Also, desperately seeking a PhD position the following year 😅 (preferably in NL). So if someone has something, HMU!
Ciao.
Nice write-up by the author of the study on these birds, the Greater Anis. While they usually brood eggs in a group (three pairs to a group), occasionally another Greater Anis outside the group might drop a egg (brood parasite). How this might affect the success of the egg layer is the purpose of the study.

Some birds can avoid paying the costs of parental care by laying their eggs in other females’ nests, while others share those costs by breeding in a cooperative group. We studied the benefits of both strategies – cooperative breeding and brood parasitism – in Greater Anis, a species of tropical cuckoo. Our goal was to understand why individual females might choose one strategy over another. We found that cheating isn't as easy as it seems, and that female anis typically do it only after their other reproductive options have failed.
