Today’s walk around the Stroud Preserve was very calm, but full of birds. The first four birds of the day were an adult Cooper’s Hawk, adult Bald Eagle, male Kestrel, and adult Red-tailed Hawk. Not a bad start. The parking lot was completely empty when I arrived and I saw almost no people despite the nice weather. For the past couple of weeks I’ve been reading about an invasion of Pine Siskins to the Delaware Valley. Flocks of hundreds of them seemed to be everywhere except the Stroud Preserve. Finally today they arrived.
