One of the questions that I was asked was about how the noise from uptown events (like the NASCAR Speed Street event) would affect the behaviors of the Peregrines on their nest. In general, living in a place like the one they chose on the 40th floor should have prepared those birds for dealing with the sights and sounds of the city, already. As I looked around, though, I found that other people have examined the effects of noise on these birds more specifically. If jet plane noise doesn’t have much of an effect on parental behaviors, then a bit of NASCAR shouldn’t have too much of an effect.
Interestingly, the pattern that they found in these birds affected by jet engines was that males spent less time at the nest and females spent even more time at the nest- during the incubation periods. Apparently, there was no affect of noise on the provisioning rates of the birds. Given that the chicks are still looking pretty good, I’d say that our nestlings handled that stress pretty well!
