Media notes
Digitized 1/2022. The original cassette was played on a Sony CFO 5500 CD Radio Cassette-Corder and the output was piped via the headphone jack to the line-in jack of a Marantz PMD661 Mark II solid state recorder, where it was digitized as a 96k 24-bit wav file. The wav file was reduced to 16-bit with Acoustica MP3 to Wave Converter PLUS software, for editing with Signal Sound Analysis Software, which produced the 96k 16-bit WAV file submitted to Ebird. No filter was ever applied.
Observation details
First recordings of dawnong of this species. All four cuts are from one continuous performance by the same bird. Bird not seen in dim predawn light. Identified by great similarity to dawnsong of C. fumigatus (and C. pertinax minor) and because of match with Stiles and Skutch transliteration "Fredrick-Feear." Furthermore, both the Pip and Feear notes are essentially identical to calls given in daytime by seen Dark Pewees in this locality. Finally, the Fredrick phrase, not heretofore recorded for the Dark Pewee, is characteristic of Contopus, being found not only in fumigatus and pertinax, but also in the more distantly related virens, sordidulus, and cinereus. Dark Pewees much in evidence along this road, as pointed out by innkeeper Gary Roberts.
