As most falcon-watchers know, the Peregrine Falcons have resumed incubating their eggs after abandoning them for about two days at the end of April. The two days or so the eggs were left exposed to the elements were rainy and chilly. At the time, when the birds were gone, that appeared to be it – the end of the 2017 nesting cycle. Is that still the case?
My understanding is that the falcons more or less commenced incubation on 24 April after the third egg was laid. They then abandoned the eggs on the morning of the 29 April after the fifth egg was laid. About two days later they resumed sitting on the eggs. These have been unusual events and my opinion is that I am very skeptical anything will come of this resumption of incubation, but I’ll also admit that I am also uncertain about the final outcome. I’ve reached out and chatted with a couple of raptor experts and they’ve voiced similar opinions of skepticism and uncertainty. It may also be valuable to recognize (again) that this falcon pair has also experienced very low hatching success of individual eggs the past two years. Only one egg of four hatched in 2015 and one egg out of five hatched in 2016. Even without the irregularities that have occurred this year, some or even all of the eggs could have already been infertile.
