Black-Throated Gray Warbler

Look high in the canopy of coniferous and mixed woodland across the western United States and northern Mexico, where it forages actively along branches and foliage for insects. A buzzy, rising song is often the first clue to its presence, since the bird itself can be hard to pick out against foliage. Spring and early summer, during the breeding season, offer the best chance of hearing males singing from exposed perches.
