I birded Pastorius Reservoir SE of Durango this evening. At 8:20 along with another birder, I observed a silent nighthawk foraging in the general of the inlet canal which we concluded was a Lesser Nighthawk. The bird seemed small and fluttery in its flight pattern which was low at tree level while we observed it. Both of us agreed that the white wing bars were quite close to the wing tip. Typically, Common Nighthawks don’t arrive until toward the very end of May in Colorado, and early nighthawks should be examined for the possibility of Lesser.
