CONSERVATION STATUS

Least Concern

The Alder Flycatcher can be found as a native species in numerous countries, including the United States, Argentina, Mexico, Peru and Costa Rica. This species calls such a large area home that its range exceeds 7 million square kilometers. It is estimated that the global population of this species is around 49 million individual birds. Due to the fact that there has not been a decline in population of more than 30% over the last decade, the population is not believed to be in danger of declining. Consequently, the Alder Flycatcher is currently a Least Concern evaluation.

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.
