Detalhes da observação
**Very late. As if it wasn't surprising enough to find a single Common Nighthawk in mid-January, I documented TWO birds hawking for insects low over Campus Lake for the duration of ~30 minutes, after which I left the birds there. Photos of both birds appear to eliminate Lesser Nighthawk due to the white bar being relatively close to the base of the primaries (and the primary coverts); clean, mostly unspotted, dark primaries and secondaries; and a distinctly pale, contrasty gray bar on the upperwing coverts. The first bird lacked a white subterminal band to the tail and was thus a female or an immature male. The second individual, which seemingly materialized out of thin air around perhaps 5:20, was an AHY male, as evidenced by a complete white subterminal tail band. This follows on the heels of a couple late December reports (singles on 12/24 at University Lakes and 12/29 at Campus Lake). Silent.
