The breast is washed with olive. The upper part of the bill is dark; the lower part is yellowish. This bird's song is an explosive peet-sa. The call is a soft peet. They also have a call similar to that of the northern flicker. A unique two-note song described as "ka-zeep" helps to identify this species. Measurements: Length: 5.5–5.9 inches (14–15 cm) Weight: 0.4–0.5 ounces (11–14 g) Wingspan: 8.7–9.1 inches (22–23 cm) == Taxonomy == Originally described in 1810 by ornithologist Alexander Wilson, its first scientific name was Muscicapa querula. The Acadian flycatcher is the only member of its clade within Empidonax, but is most closely related to willow and alder flycatchers. Because of the similar appearance of the Empidonax flycatchers, the Acadian flycatcher owes its name to a misidentified type specimen for the species, taken in the historic Acadia region of Nova Scotia. Despite its common name, the Acadian flycatcher does not have a native…
