Flycatcher calls

The alarm calls of the Alder and Willow Flycatcher are very different, and a good way to identify an unknown bird if you are lucky enough to hear it call.

The Willow Flycatcher call is a whit (June, NJ).












The common call of the Alder Flycatcher sounds like the first note of the Olive-sided Flycatcher song (July, ME).











Another Alder Flycatcher call (July, ME).













The Least Flycatcher call is a whit, similar to Willow Flycatcher, but softer and lower (Sep, NJ).













The Acadian Flycatcher has two commonly given calls, a descending pwer and a rising pweet.
In my experience, "pwer" is a call given by the female. This was a female returning to nest with eggs (June, PA).












Another example of pwer with another call, a short trill (May, PA).












Pweet, note the subtle difference from pwer.
(May, PA)












The chip call of the Eastern Phoebe is commonly heard. It is similar to the chip of the Swamp Sparrow, but a little softer (Apr, PA).













Interaction calls between four phoebes (Mar, PA)























The Eastern Wood-Pewee has a surprisingly large repertoire of calls.
The pewee call is probably the one most often heard (June, NJ).











call at 6s









Eastern Wood-Pewee calling at dawn (June, NJ).












A longer version of the call (July, PA).













Squeaky interaction calls between two pewees (May, NJ).













Chip call (June, NJ)












Bill snapping and other calls by two birds interacting (with Tufted Titmouse scolding, June, NJ)












chip-hoo









(June, NJ)


short call at 11s








part of long call starting at 18s









A pewee call that sounds a little like an Alder Flycatcher (presumed, bird not directly seen vocalizing, June, NJ).












Eastern Kingbird zeer calls (July, NJ).












Female calling in foreground and twittering, male calling zeer in background, after female had flown from incomplete nest to adjacent tree (May, RI).












Great Crested Flycatchers have vocalizations that can be termed as calls or song depending on the delivery (see Flycatcher songs).
They also have calls that are used in interactions. The following were made by pairs of birds in flight or just landed, with one bird being chased by the other.
