And the folks who worked with non-game birds, in general, didn't have the rope skills, as it wasn't much of what they did. So, when the Peregrine falcons started nesting under bridges, the bird people called us mammal people to come out and do the rope work needed to capture the falcon chicks for banding (and a bit of blood work to assess disease potentials). Note: This wasn't the first time for this stuff, but my first time.
So here I am, under the Turnpike Bridge in Philadelphia (some 210 feet above the water) on the catwalk.
However, Cal Butchkoski, at the time a Wildlife Technician for the PGC and my boss, did have to rappel down. And the nest wasn't just sitting there in the open, but in a box beam. So he had to climb into the beam to catch the Peregrine chicks and then ferry them up to a bird person for banding and blood work.
But we weren't done. Given the difficulties of accessing the chicks in the beam (plus the more likely troubles with disease and parasites in such a space), we mounted nesting boxes in an area that could be accessed much more easily with the hopes that the birds would use them instead.
And while these photos aren't studio quality, it should be noted that all of this was done with a stiff wind and in a heavy drizzle.
I am happy to have contributed to helping with the Peregrine work in Pennsylvania (and I did this stuff two or three more times), yet I am glad to not be doing it anymore.
