Overnight Visit From Adult on Cahow Cam – May 18, 2017
It’s a full-belly Friday for the Bermuda Petrel chick thanks to a late night visit from this adult cahow on Thursday.

Over the next two weeks, the larger-than-life cahow chick will begin to shed its downy plumage and its first fresh set of flight feathers.
