When flushed, the white outer tail feathers of the Vesper Sparrow
are easy to observe. Other birds with this field mark are American
Pipit, Horned Lark, Lark Sparrow
and longspurs. All lack the heavily
streaked breast of the Vesper Sparrow.
When perched, the Vesper Sparrow looks similar to several other species
of sparrows. Savannah has a yellow
supercilium, pale central crown stripe, shorter tail and lacks rusty
shoulder and eye ring. Song has rounded
tail, breast spot, and lacks rusty shoulder and eye ring. Lincoln's
has a buffy breast. Baird's and juvenile Grasshopper
are larger-headed and shorter-tailed. |
