Songs
Males sing a repeated series of gurgling, burry notes just before dawn until about seven in the morning during the breeding season. Their non-musical song changes in pitch from high to low and sounds rather bumpy and stuttered as if they were sputtering through a whistle. The dawn song may include the ha-wheer call or the ka-brick call. The length of each song varies, but each burst is about 1 second long with about 2–3 seconds of silence between bursts.
Calls
Ash-throated Flycatchers have 4 distinct calls that they give singly, in pairs, or in combination. They make a short and rapid huit call or string them together into a trill that lasts for 4–5 seconds. The br-ick call is less than 1 second long and rises in pitch. They give a wheer that varies from relatively flat in pitch to rising or descending depending on their level of excitement. The final call is a short, low-pitched, burry urg. They combine these 4 basic calls to form 2 additional calls that are often part of the dawn song, the ka-brick and ha-wheer calls.
