. Birds in Kansas. Birds -- Kansas Identification. 222 BIRDS IN KANSAS. Period of Occurrence: The Greater Yellowlegs is one of the earlier shorebirds to appear in the spring. The normal arrival time is around 21 March; the earliest record is 27 February. It gener- "~}r-\r^ ally leaves by 22 May but has been recorded on 12 June. The average southward arrival is around 2 August; 12 July is the earliest date. Migration continues until 29 October, with an extreme fall date of 16 December. Birds recorded in the summer are probably first-year, nonbreeding birds that have only moved as far north as Kansas. Also, shorebirds thought to be non- breeding birds sometimes return south soon after reaching the breed- ing grounds. That may account for the large number of shorebirds found in Kansas in late July and August. Habits and Habitat: These yellowlegs are usually found around marshes, rivers, lakeshores, or temporary pools of water. They, like the Killdeer, are very vocal and are one of the first marsh birds to cry an alarm when possible danger approaches. Field Marks: Distinguishing the Greater from the Lesser Yellowlegs is a hard task visually unless the two are seen side-by-side. However, the calls differ; the Greater Yellowlegs usually has a three-note whistle, while the Lesser Yellowlegs has a one- or two-note whistle, rarely three-notes. Food: Greater Yellowlegs eat primarily aquatic invertebrates and small minnows. In damp grassy meadows, they probably eat insects and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Thompson, Max C; Ely, Charles A.
