What a delightful stroke of luck to notice this tiny bird perched just outside my window. This is the first and only sighting I’ve had of the Wilson’s Warbler here. They only pass through my area during migration, so they don’t stick around.

Notice the intense darkness and gloss of the black eye, especially in contrast to the bright yellow.

The black spot on the crown identifies this one as a male. Depending on the subspecies, this mark would be either smaller or non-existent on a female.

A few details from Wikipedia’s Wilson’s Warbler page:

Range
It breeds across Canada and south through the western United States, and winters from Mexico south through much of Central America. It is a very rare vagrant to western Europe.

Habitat
The breeding habitat is fairly open woodland with undergrowth or shrubs and thickets in moist areas with streams, ponds, bogs, and wet clearings. it winters in overgrown clearings and coffee plantations, forest edges, deciduous forests, tropical evergreens, pine-oak forests, mangroves, thorn-scrub, riparian gallery forests, brushy fields, and mixed forests . At all seasons, it prefers secondary growth, riparian habitats, lakes, montane and boreal forests with overgrown clearcuts.

Diet
They feed primarily on insects gleaned from leaves and twigs, or caught by flycatching. Some of these insects include beetles, bees or caterpillars. It also eats some berries.
