Vaux's Swift (Oregon Swift, Vaur's Swift)

The Vaux's Swift is a tiny, cigar-shaped bird with long, sickle-shaped wings and a very short tail adorned with spiny tips. It spends almost its entire life airborne, catching insects on the wing with erratic, fluttering flight styles. Its plumage is predominantly dark gray-brown, slightly paler on the throat and rump.

Uniform dusky brown to grayish-black with a slight greenish-bronze iridescence on the upper surface and a paler, grayer tone underneath

Strongly pennaceous with tightly interlocked barbs and barbicels to withstand high wind resistance; no afterfeather

Stiff, smooth, glossy surface with minimal flexibility, designed for aerodynamic efficiency

Extremely narrow profile, stiff vane structure, dark brownish-gray coloration with subtle iridescence, and a short, rigid shaft characteristic of high-speed aerial insectivores

Old-growth coniferous and mixed forests, particularly near large hollow trees for roosting and nesting, as well as open skies where they forage for insects

Breeds along the Pacific coast and interior mountains from southeastern Alaska down through California, migrating to wintering grounds in Mexico and Central America

Acts as a primary aerial insectivore helping to regulate flying insect populations; relies heavily on old-growth forest snags, making it an important indicator species for forest ecosystem health

Chimney Swift (Chaetura pelagica), which is slightly larger and darker in the eastern part of North America; overlap in migratory or overlapping western ranges requires careful size and geographic context

Vaux's Swifts roost communally inside large hollow trees, sometimes numbering in the thousands, packing tightly together on the vertical walls in a formation known as a living cylinder

Good condition with intact barbs and minimal fraying, showing standard wear typical of a migratory aerial insectivore
