Red Phalarope
Phalaropus fulicarius
The red phalarope is about 21 cm (8.3 in) in length, with lobed toes and a straight bill, somewhat thicker than that of red-necked phalarope. The breeding female is predominantly dark brown and black above, with red underparts and white cheek patches. The bill is yellow, tipped black. The breeding male is a duller version of the female. Young birds are light grey and brown above, with buff underparts and a dark patch through the eye. In winter, the plumage is essentially grey above and white below, but the black eyepatch is always present. The bill is black in winter.

Upland Sandpiper
Bartramia longicauda
An adult is roughly 30 cm (12 in) long with a 66 cm (26 in) wingspan. The average weight is 170 g (6 oz). This odd bird has a small dove-like head on a long neck. It is heavily marbled black and brown on the back and wings. The neck is streaked with dark brown which continues down to the breast and on to the flanks. The belly and undertail coverts are white, and the tail is quite long for a sandpiper. The upland sandpiper also has a white eye-ring and long yellow legs. Voice: Upland sandpipers can be identified by a distinctive call, sometimes called a "wolf whistle", which features a long, ascending whistle followed by a second rising and/or falling call. These sounds are often made while the bird is landing or while flying high.
