Field Marks and
Identifying Characteristics:
Back, wings and nape grayish brown. Faint wingbars.
Face, paler shade of grayish brown with black line from base of grayish black bill to just behind the black eye.
Buffy/creamy white supercilium.
Cap seemed mostly grayish brown (about the same color as the back and nape) but was tinged with a small amount of rufous so as the bird moved, the rufous caught the light and stood out a bit more. However the cap never appeared bright rufous, only a rufous-tinged grayish brown at its brightest.
Throat, breast, and belly buffy/creamy white with grayish streaks along the edges of the throat and fading down the edges of the breast.
Edges of belly tinged with pale grayish yellow.
Undertail coverts bright yellow.
Upper tail grayish yellow olive which clearly contrasted with the grayish brown back.
Inflight, tail showed yellowish streaks with white corners.
Black legs.
Song or call & method of delivery: Trilling song delivered when perched on tall dead grass stalks and just before flying to new perch. Chip flight call as bird was flying from stalks to ground near pond. Occasional chip call as bird was hopping and foraging on the ground.
Behavior: Perching on and singing from tall dead grass stalks; flying from stalks to perch on the ground near marsh/pond; extensive foraging and hopping on ground; tail cocking and tail movement while on ground.
Habitat: Open area covered in dead tall grass stalks, with sparse trees and bushes surrounding a small marsh/pond (south of main ranch compound).
Similar species and how
were they eliminated:
Tail movement, ground foraging and described plumage eliminate all other warbler species.
Previous experience with
this & similar species:
Very familiar with common warbler species of Utah and fall migrants in Utah. Have seen one other Palm Warbler during fall migration in Utah as well as several breeding Palm Warblers in other states.
