Wilson’s Snipe
Wilson's Snipe
Gallinago delicata
At a Glance
Often overlooked in migration and winter, the snipe is a solitary creature of wet fields and bogs, seldom seen on open mudflats. Flushed from the marsh, it darts away in zigzag flight, uttering harsh notes. The Wilson's Snipe becomes more flamboyant in the breeding season, when it often yammers from atop a fencepost or dead tree. At night on the nesting grounds, the ghostly winnowing flight sound of the males often echoes across the marshes.

Behavior
Eggs
4, sometimes 3. Brown to olive-buff, marked with dark brown. Incubation is by female only, 18-21 days.
Young
Downy young leave nest shortly after hatching. Parents may split brood, each caring for 1-2 of the chicks. Parents feed young at first, before they learn to find own food. Age at first flight about 19-20 days.
Feeding Behavior
Forages mostly by probing in soft mud; bill tip is sensitive and flexible, allowing the snipe to detect and capture prey underground. Also captures some food in shallow water or from surface of ground.
Diet
Mostly insects and earthworms. Eats many insects that burrow in damp soil or live in shallow water, such as larvae of crane flies, horse flies, various beetles, many others. At some places, diet includes many earthworms. Also eats some leeches, crustaceans, mollusks, spiders, frogs, leaves, seeds.
Nesting
In breeding season, especially at night, male performs "winnowing" display: flies in high circles, periodically making shallow dives; during dive, vibration of outer tail feathers produces a hollow whinnying sound. In aggressive and distraction displays on ground, bird crouches, raising and spreading tail to show off pattern. Nest site is on ground, usually well hidden in clump of grass or buried in tundra vegetation. Nest (built by female) is shallow depression lined with fine grasses, leaves, moss, sometimes with overhanging plants woven into a kind of canopy.
Climate Vulnerability
Conservation Status
Probably far more abundant at one time, reduced by market hunting in late 19th century and by loss of habitat; however, still widespread and common.
