I would just like to thank everyone for their supportive comments and emails. As a result of some of the emails, I have been searching the Flickr index for NYC raptors.
The results have been astounding. It seems New Yorkers are paying attention. Here's one regarding the rescue of a fledgling from the 55 Water St. nest.
And here's one from this past August of an injured adult near Rockefeller Center. Possibly the result of a territorial battle.
This is one is from Chicago.
And from San Jose.
Where there is a "peregrine rescue group" on standby during fledging.
Seems most North American cities have nesting peregrines (and raptors for that matter) and the mortality rate for fledglings in these urban environments is exceedingly high. It therefore becomes incumbent upon us to assist these birds as best we can with the tools at our disposal. This methodology should also be applied to kestrels, merlins, redtailed hawks and owls. Hopefully by next year's fledging season we can organize amongst ourselves to have most of the riskiest nests covered during this critical time!
