Lesser Yellowlegs (Tringa flavipes) is a medium-sized sandpiper. It nests in meadows and open woodlands from Alaska to Quebec, and winters mostly in South America. It is a common to locally abundant migrant throughout Minnesota from late March to early June and from July to October. In Minnesota it is found in marshes, wet meadows, mudflats, and flooded agricultural fields, and on the shores of lakes and ponds. It eats mostly flies, beetles, and other insects, but also spiders, small fish, snails, crustaceans, worms, and seeds.
The population of Lesser Yellowlegs is declining due to habitat loss in part the result of climate change. However, the species range is extremely large and the species is not considered vulnerable.
A Lesser Yellowlegs looks similar to a Greater Yellowlegs but is smaller. The adult is 10″ to 11″ in length and has a wingspan of 24″. It is a slender shorebird with a small head, a thin bill, and long, bright yellow legs. The nonbreeding plumage is uniformly gray on the upper side with fine, dark streaking. The underparts are white with small gray spots. There is a dark line from the bill to the eye. The bill is straight, thin, entirely black, and about the same length as the head.
