Prey Exchange, Cornell Hawks Cam, 9 March, 2016
Ezra and Big Red exchanged prey on the “Weill” nest yesterday. They have been increasingly active on this 2013-2014 nest site, effectively “choosing” it for this year’s brood. Looking forward to the G generation!
The Cornell Lab of Ornithology writes about this:
Big Red and Ezra have been at it again, spending time at two nest sites; fortunately, we already have cams installed at both locations. Over the last two weeks it has become apparent that the site nearest Weill Hall (used during 2013-14) is the most likely site, and each hawk has been provisioning the nest with twigs, greenery, and bark.
Ezra has exchanged prey in the nest bowl with Big Red several times, and we expect the arrival of the first egg sometime in the next 10 days. Stay tuned for the fifth cam season for Big Red and Ezra! Watch cam.
