INTERESTING FACTS

  • The population on the Channel Islands may actually be a distinct species. It is larger than mainland birds, has a longer bill, a paler chest, slightly different vocalizations, and differs genetically.
  • The species name of the Pacific-slope Flycatcher, difficilis, is appropriate. It means "difficult," and this species is extremely difficult to distinguish from the similar Cordilleran Flycatcher.
  • These two species were formerly considered a single species known as Western Flycatcher.
  • A group of flycatchers has many collective nouns, including an "outfield", "swatting", "zapper", and "zipper" of flycatchers.
