On Monday, I photographed both Lesser and Greater Yellowlegs foraging in a shallow duckweed-covered pond at Farmington Bay WMA early in the morning. Since I am asked for bird identification frequently, I thought I would do a comparison between the two species today. They have similar plumage, both have long yellow legs and are often found in the same type of habitats.<\/p>\n

Lesser Yellowlegs, as their common name implies, are the smaller of the two yellowlegs species. Size in the field can be deceiving, though especially when both species are not present. That tip actually applies for all birds. I’ve seen people say that a Cooper’s Hawk was as big as an eagle, and we know that is not the case.<\/p>\n

So how do I know which is which when I have only one of the two yellowlegs species in my viewfinder? I look at the bill.<\/p>\n

Lesser Yellowlegs have straight, dark bills that are about as long as the width of their heads.<\/p>\n

\"GreaterGreater Yellowlegs foraging in a shallow pond \u2013 Nikon D500, f7.1, 1\/2000, ISO 640, -0.3 EV, Nikkor 500mm VR with 1.4x TC, natural light<\/span><\/p>\n

Greater Yellowlegs have a longer bill than Lesser Yellowlegs which are about 1.5 times as long as the width of their heads. The thicker bills of Greater Yellowlegs also has a slight upwards curve to them compared to the straight bill of the Lesser Yellowlegs.<\/p>\n

In addition to those differences, the nasal openings, or nares, of Greater Yellowlegs are further away from the feathers of their faces than the nares of Lesser Yellowlegs which are very close to the feathers of their faces.<\/p>\n

\"LesserLesser Yellowlegs standing still \u2013 Nikon D500, f7.1, 1\/1600, ISO 640, -0.3 EV, Nikkor 500mm VR with 1.4x TC, natural light<\/span><\/p>\n

The calls of these two species are also different. Lesser Yellowlegs have a softer, hesitant calls<\/span><\/a> which are usually one to two notes. Greater Yellowlegs have more strident and louder sounding calls<\/span><\/a> which are typically three to four notes.<\/p>\n

I am more familiar with the calls of Greater Yellowlegs because I see and hear them more often. When I only hear one to two note calls them I start looking for Lesser Yellowlegs for visual confirmation.<\/p>\n

I have also noticed that Greater Yellowlegs foraging behaviors are more aggressive and frantic than Lesser Yellowlegs. Lesser Yellowlegs pause more and are slower when foraging.<\/p>\n

When I can’t get a good look at the bill of a yellowlegs in the field I watch for their foraging behaviors or listen for calls to help with identification.<\/p>\n

Life is<\/em> good.<\/p>\n
