 the Philippine Islands,

In the gray-spotted flycatcher there is some variation in the brown 

 streaks of the under parts, but this species is not easily mistaken for any 

 other bird except Piprisoma ceruginosum which has a very differently 

 shaped bill. The gray-spotted flycatcher is one of the commonest winter 

 visitants and is found in small numbers throughout the islands.
