Family Reunion In Bermuda Petrel Nesting Burrow β May 20, 2019
Both adult Bermuda Petrels arrived for a short overnight reunion with their chick in their artificial nesting burrow on Nonsuch Island, Bermuda. Cahows nest in underground burrows or deep rock crevices, and only nests deep enough to be completely dark are chosen. 80% of all cahows now nest in artificial concrete nest burrows constructed for them as part of the Cahow Recovery Program.
The CahowCam is a collaboration between the Cornell Lab of Ornithology and the Nonsuch Expeditions. You can watch the cam live at http://allaboutbirds.org/cahows.
