Falcon watch report/update on Mariah and her new mate.

While we wait in anticipation for a Princess/Trey sighting; I found this on the Imprints Rochester site. Jess, who I think is one of the falcon watchers has posted this in reply to a question that we also had about Mariah's eggs - the response is from the DEC: (I hope it's ok to post it here)
After all the questions about Mariah mating with T-C and whether she could lay eggs based on their copulation activity we asked the DEC.
Their answer is that all the evidence points to Peregrine females being able to store usable sperm for only a couple of days. Under controlled laboratory conditions some artificial insemination efforts have produced 2 or 3 eggs from a single insemination, but the timing has to be very precise. In the wild that’s not likely to happen.
Since it takes about two days for the egg to form and be laid, Mariah needs to have a pretty steady supply of sperm while she’s in her egg-laying phase in order to produce viable eggs. That’s one reason why we continue to see copulation behavior throughout the egg-laying cycle.
So it doesn’t look like any of the mating activity between Mariah and T-C would have resulted in laying fertilized eggs.
