Tree Swallow (with feathers collected from Wild Turkey / Waterfowl)

Tree Swallows build sturdy cup nests of grass and straw lined lavishly with large feather feathers gathered from wild birds (often waterfowl, turkeys, or poultry) to insulate their clutches of eggs during early spring incubation.

Bold dark brown/black and white alternating bands or tipped pattern, with fluffy grey down at the bases

Pennaceous towards the tip with prominent dark and light banding; fluffy plumulaceous down at the calamus base

Thin, flexible central shaft; high barb density creating soft insulating surfaces

Soft, fluffy, and insulating; light and smooth upper pennaceous vane

Body contour feathers lining a cup nest structure containing speckled eggs

Distinctive nest lining behavior using large contrastingly banded body feathers surrounding small heavily spotted passerine eggs

Open fields, marshes, meadows, lakeshores, and agricultural areas near water with cavity availability or nest boxes

Breeds across northern North America and Alaska, wintering in southern US, Mexico, and Central America

Voracious aerial insectivore helping regulate flying insect populations including mosquitoes and midges; crucial cavity nester

Violet-green Swallow, Barn Swallow, Eastern Bluebird (similar nest box users but different nest lining habits and egg color)

Tree Swallows famously compete fiercely for feathers blown in the wind, playing aerial catch games before adding them to line their nests for insulation.

Nest boxes are widely built by naturalists and backyard bird lovers to support local swallow populations and control insect pests.

Look inside wooden nest boxes in spring; a cup of dry grasses heavily lined with prominent white, gray, or banded poultry/wild bird feathers is diagnostic of Tree Swallows.

Feathers show mild wear from construction and nesting activity; generally intact with natural fluffy texture preserved
