Field Notes
Description:
A common, tall, long-legged shorebird of freshwater ponds and tidal marshes, the Greater Yellowlegs frequently announces its presence by its piercing alarm calls.
Habitat:
San Francisco Bay wetlands
Notes:
The two yellowlegs species are very similar. Size is marked different when they appear together and can be compared against each other. Greater Yellowlegs's bill appears slightly upturned and blunt-tipped, while Lesser Yellowlegs's bill is straight and sharp-pointed. Lesser's bill is always dark, while Greater's bill is grayish at the base in nonbreeding season. Voice is best distinguishing character: Greater gives three or four piercing notes, Lesser two rapid, softer short whistles (sometimes or or three).
