Long-Billed Dowitcher (Limnodromus scolopaceus) lives in wet coastal plains across North America. It feeds on insects & crustaceans. Its conservation status is Near Threatened.
Fascinating facts about the Long-Billed Dowitcher
- Genetic studies indicate that the long-billed dowitcher and its short-billed cousin diverged more than four million years ago. For many decades the two were lumped together, even being treated as a single species in 1927, and they were reinstated as separate species after Frank Pitelka published his monograph in 1950.
- Although the long-billed dowitcher looks almost identical to the short-billed form, especially in winter plumage, birders rely on their distinct winter flight calls to tell them apart. They were finally recognised as separate species in 1950.
- The long-billed dowitcher's bill ranges from 62 mm to 72 mm, roughly twice the length of its head, providing a long, precise probing tool. Bills are straight and black, turning yellow-olive near the base, and males tend to have the shorter measurements that match their smaller bodies. This specialised bill supports the bird's characteristic "sewing-machine" foraging motion in shallow water.
- Long-billed dowitchers probe shallow water with a rapid "sewing-machine" motion, keeping their heads submerged and using tactile receptors at the bill tip to feel prey. While breeding they rely heavily on chironomid larvae and other insect larvae, adding occasional plant matter and seeds. In migration and on wintering grounds their diet expands to include polychaetes, crustaceans and molluscs.
- Male long-billed dowitchers begin courtship by singing to a female and then chase her in swift aerial pursuits that showcase speed and agility. After the pair mates, the male continues to sing while hovering about fifteen feet above his territory. These pairs usually remain monogamous for the breeding season, though they do not keep the same mate in subsequent years. The aerial display and post-mating song reinforce the male's territory and attract the female.
