Tennessee Warbler
Vermivora peregrina

Native Range: North America

Notes: nests in boggy spruce woodlands but is much more catholic about suitable habitats during migration; very closely related to Orange-crowned Warbler, best distinguished from the latter in winter by its whitish (rather than yellowish) undertail coverts; both species may be told by a bill that is very acute (sharply pointed), even by warbler standards.

quite drab; pale eye line; olive-yellow upperparts (California; 2007-09-30)

weak wingbars; whitish-yellow underparts (California; 2007-09-30)
