Day 79: Cassin's in a box

Cassin's auklets are one of the few species that are still in the midst of breeding right now. We had a very high rate of double brooding this year. After pairs raised one chick they decided it was so much fun they wanted to do it again so they started over. Many of these second broods are now hatching, and young chicks need to be fed. This photo was taken around 10:30pm and this Cassin's probably just came in to feed its chick in the nest box and is now hanging out near the entrance tube. Cassin's are very vocal at night and socialize quite a bit outside their burrow and boxes. Their calls have been described as sounding like crickets on steroids.
