What's going on at Great Spirit Bluff? We've been getting a lot of questions about it since Saturday morning, when Michelle was spotted lifting and nibbling at one egg in the morning and eating another in the afternoon. Why was Michelle eating her eggs? Why aren't more eggs hatching?
Michelle laid five eggs beginning on April 4th. Falcons, especially smaller males, often struggle to incubate that many. One egg broke up on May 9th, Michelle ate a 'hatching' egg on May 18 (we think the embryo suffered cold-related developmental injuries and died during hatch), and Michelle removed an empty egg from the nest this morning, May 21. The egg must have frozen and cracked, emptying its contents but leaving the shell relatively intact.
At present, we have one eyass and one unhatched egg in the box. We don't know whether or not the remaining egg will hatch. It hasn't burst yet, but Michelle has also left it un-incubated for relatively long periods of time. Michelle and Travis won't curtail hunting or feeding activities, so the young falcon (or falcons, if the second egg hatches) will reap the benefit of abundant food.
Bob commented that he'd seen more egg-eating this year than ever before. The extreme temperatures may have contributed to more freezing and breakage than usual, especially since falcons don't start full incubation until after the third egg is laid in a four-egg clutch, or the fourth or fifth egg is laid in a clutch with more than four eggs. Cracked, dead eggs won't hatch, and they provide falcons with an important source of protein, calcium, and calories.

I'm thinking prey remains might have been stuck to the egg, since she never appears to have penetrated it with her beak and she tucked it back under her instead of eating the whole thing. We've seen eggs eaten at Sherco, Allen S. King, and the TV loft this year. Egg eating tends to happen quickly and the entire egg is consumed. Sharing the video to see what Bob thinks - I'll get back to you. Thanks!
