INTERESTING FACTS

  • The Alder Flycatcher is so similar to the Willow Flycatcher that they were once thought to be the same species. Song is the only definitive way to tell them apart.
  • An estimated 63% of their population breeds in Canada's boreal forest.
  • In an experiment on song learning, Alder Flycatchers were "tutored" with Willow Flycatcher song in the first two months of life. The next spring, they sang normal Alder Flycatcher song.
  • A group of flycatchers has many collective nouns, including an "outfield", "swatting", "zapper", and "zipper" of flycatchers.
