"Songs of this species vary from 1 to 2-4/5 seconds in length. There are usually about seven notes per second. Only 3 of my records show any irregularity in the time of the notes, that is having some notes that are shorter or longer than the others. Pitch of the songs varies from F´´´ to E´´´´, a half tone less than an octave. Single songs vary from one to four and a half tones, averaging about two and a half tones; only 5 records are greater in range, and only 16 are less, nearly half of the records having the average range. "Since the myrtle warbler winters in Connecticut, I am able to get the first dates of singing. In 30 years of records the average date is April 13; the earliest April 2, 1923, and the latest April 25, 1920. In the Adirondacks the last date of singing noted was July 31, 1926. "The call-note, _tchick_, is louder than in most warblers. I found it pitched on D´´. Another note is a fainter _tseet tseet_, usually doubled and pitched on F-sharp´´´." Francis H. Allen (MS.) describes the song in a different way as follows: "The only syllabifications I find in my notes are of a bird heard at West Bridgewater, Vt., June 19, 1907, which sang _whee whee whee whee whee whee whee whee hew hew_, sometimes with three or even four _hews_ at the end and sometimes with only one; and one of a bird at South Tamworth, N. H., July 23, 1942, whose song consisted of two trills, _ching ching ching ching ching weedle weedle weet_. "The ordinary call-note is a hoarse _chep_, easily distinguished from the call of any other New England warbler. I have also heard occasionally a slight _tsip_ or _tsit_, suggesting a chickadee. The feeding call of the young out of the nest is a rapid succession of several explosive _chips_ or _pits_ with a rolling quality--a sort of chatter or chippering." On June 7, 1900, in Washington County, Maine, I recorded the song of the myrtle warbler as _wheedle wheedle wheedle wheedle wheedle_, repeated five to seven times so rapidly as to be hard to count and all on one key, usually ending abruptly but occasionally in a little trill. Few writers have accorded the song of the myrtle warbler much praise, but Bradford Torrey (1885) pays it this tribute: "For music to be heard constantly, right under one's window, it could scarcely be improved: sweet, brief, and remarkably unobstrusive, without sharpness or emphasis; a trill not altogether unlike the pine-creeping warbler's, but less matter-of-fact and business-like. I used to listen to it before I rose in the morning, and it was to be heard at intervals all day long."
