On Saturday, after weeks of easy hawk watching, it was harder. Octavia and Pale Male spent time on the Carlyle Hotel but otherwise were hide to find until dusk. Pale Male left the hotel and went to a favorite tree on Castle Walk, before roosting near Glen Span Arch.
After dark I listened for bats. I had listened for bats twice earlier in the week. As I had those last few nights, I had plenty of Eastern Red Bats at the Model Boat Pond, but I only heard Eastern Red Bats. On a hunch, I decided to walk to the lawn between the Summer Stage and Fifth Avenue. There I heard a large number of Big Brown Bats, and a Silver-haired Bat.
