Marbled Godwit

Large, buffy shorebirds flew in toward us, landed, seen well thru scope, long, slightly upturned bill, two toned. Very familiar with this species and believe it not to be unusual in this county this date. Hudsonian ruled out by buffy color. LB Curlew ruled out by upturned bill.

Long-tailed Jaeger

Juvy Jaeger species seen in flight, distinctive angular long-winged shape. Later on water, with overcast skies, appeared nearly black. Photos by Walbek in better light show dark, COLD brown of intermediate phase, with banding on tail, flight feathers and based on presence of brown neck band. NO warm color like Parasitic. Long-tailed based on 1-2 white shafts on outer primaries, long tail, "rear end" shape by silouhette, even without tail plumes. Tail and length obvious on water at great distance. In life I could not see any protrusion of central tail feathers. Characteristic bill seen at distance, confirmed by Glenn's photos: distal half of bill dark. Confirmed by reviewing Olsen's book and images by Maynard seen while bird in sight, next day by images by Walbek. Long-tailed is a fighter, not a cargo plane like Pomarine. Main ID pitfall is comparing to Parasitic.
