The Eggs Have Hatched!

All four Peregrine eggs have hatched and the nestlings all seem to have very healthy appetites. A few moments ago, the adult who had been sitting on the nest suddenly took off and the other adult immediately swooped in with a pigeon carcass. The feeding process may not be for the faint of heart, but it’s over fairly quickly. The adult holds the carcass between her* feet and tears off manageable bite-sized pieces.

Check out the nest box on the live webcam here. The Audubon Society of Rhode Island (ASRI) updates that page with interesting facts. For instance, the hatching began last Thursday when “the female was observed eating the eggshell to replenish her calcium levels after producing the four eggs.” And a Peregrine hatchling is called an “eyas.” (Good Scrabble word. Plural: eyases, eyasses.)

And don’t forget to support the Audubon Society of Rhode Island who have maintained this nesting box on top of the Superman Building at 111 Westminster Street for nearly two decades. Providence Raptors has the timeline and genealogy. (Peter Green no longer lives in Providence but he still participates and photographs banding day.)

I have found that noon to 2pm is a good time for catching a feeding, but that is not the only feeding. Note that once their lunch is over, the adult removes the carcass and drops it somewhere on the sidewalk below. While their primary food is pigeon, I once found the head of a woodcock on that sidewalk, so look down. And look up! You can sometimes see the adults flying around up there.

*The gender is hard to discern unless the adults are next to each other. The female will be the bigger of the two.
