New honeyguide paper published

Aug 10, 2013

Honeyguides and other brood parasitic birds are famous for tricking host parents by laying eggs that mimic their own. Honeyguide eggs mimic host eggs in size yet, surprisingly, bee-eater hosts are undiscriminating and readily accept mismatched eggs. This study shows that honeyguide egg size adaptation has probably rather evolved to trick other honeyguides, not host parents: honeyguides selectively puncture any mismatched egg already present in the nest when they lay their own, lest it be the offspring of another honeyguide female and brutally kill their own chick when it hatches.

New paper on eggshell surface properties

Stephanie McClelland’s paper entitled “Eggshell composition and surface properties of avian brood-parasitic species compared with non-parasitic species” has been published in the journal Royal Society Open Science. This study measured structural properties of the eggshells of brood parasites and their hosts around the world. The study found that…
