58 LLWOF 1963 Journal. August 7 contd. back with Magie Jay + a juvenile Hiraphila humeralis - our first on this trip. Bird was almost three postjuvenal molt Prepare these two specimens after supper. Finished notes to read, August 8 7mi. s. Piaxtla, Puebla to Oaxaca, Oaxaca. Up at 0545. Heard Hiraphila humeralis singing as made breakfast so over to record. Also got some recordings of the chatter call. John subsequently got recordings of chatter duet. While John tried to collect R. humeralis I watched a foraging pair near camp. After about an hour discovered they had a juvenile hidden in brush. Immediately got gun + tried to collect juv. Finally collected 0, then 2, + juvenile. Juv. has just started the postjuv. molt so is youngest specimen of this species available. Shows faint streaks on brown chest band. John came back with 11 birds + with 5 I collected we started to prepare specimens. Collected another singing ♂ humeralis at 1145. Finished birds by 1300 + packed car. Turned south on Pan American Hwy. hoping to find camping spot near Acotala, Puebla. No luck. As neared Oaxaca border we passed thru a zone of scrub oak + other broad-leaved trees but no legumes. My account for loss of humeralis.
