It’s the 2015 nesting season for the downtown Cincinnati Peregrine Falcons! So far 3 eggs have been laid. Thanks to a faithful RAPTOR Inc. follower and photographer, James, the first one was reported on the morning of Match 26th. Peregrine Falcons usually lay eggs ever 2 – 3 days and sure enough, the second egg was laid March 28th, followed by the third egg on the Morning of March 31st, 2015. We’ll have to watch and see if a fourth egg is laid!
The photo above is possibly the female watching over the eggs. Before incubation starts, the female is most often seen standing by the nest, guarding, and often looking out during the day. During incubation, it is the female, who is most often incubating during the day and all of the night. The male does most of the food gathering and incubates the eggs for short periods, so the female can eat away from the nest.
We are guessing that this is the same adult falcon pair as last year. Since we have not seen any leg bands on the falcons, we do not have any history of the adults. The bands have a unique identification number, which could provide information such as the age of the bird or location of banding. The falcons occupying this nest box for the past 2 years have been unbounded, so we will never know if they are the same pair as last year or their history.
Typically, Peregrine Falcons lay their eggs and do not begin incubation till the third or fourth egg is laid. This behavior results in the eggs all hatching within a day or two, and as we noticed last year, the chicks looked about the same size. With the cold snap here in Cincinnati, we noticed the adults sitting on the egg or 2 eggs to prevent them from getting cold. This year, the hatching of the eggs may be spread out over a longer time period. We’ll have to watch and see what happens!
