In its open country habitat, the Savannah sparrow is most similar to
vesper and song sparrows. It can be told from both by its yellowish
supercilium, white central crown stripe and short tail. Baird's and
juvenile grasshopper sparrow are larger-headed and billed. When
flushed, the Savannah sparrow tends to fly fairly high to its next
perch whereas song sparrows fly low and pump their tails, vesper
sparrows often show considerable white in the tail and grasshopper
sparrows fly very low.
