Thought folks might like to see some photos from another of our urban raptor nests. I took these pictures this morning while banding at one of our local peregrine falcon nests. The falcons laid three eggs but only one hatched. Something happened to the adult male peregrine at this nest site a couple of days after the egg hatched and the female has been raising the nestling all on her own. Peregrines don't abandon their young, so he likely befell some sort of accident. It is pretty tough for a single falcon to raise her young solo...during the first week after the male disappeared she had to race of the nest to hunt food and then race back to keep her nestling from getting cold. Now that the nestling is older, mom can spend more time away from the nest. It is probably a good thing that she only has one mouth to feed. The nestling is in a nest box that was installed for peregrines on one of our local bridges several years ago. Peregrines do not build stick nests--instead they lay their eggs right onto sand and gravel that accumulates on ledges. The nest box is full of pea gravel.
We will banding three more local peregrine nests on Monday morning. There are actually eight active peregrine nests in the Portland area--5% of the total nesting peregrine falcon population in Oregon!
