3 birds
Recording ♂ vocalizations when another bird started
chatter. ♂ flew to same bush - 30-40 feet away - & began
chattering also. A 3rd bird arrived & all flew into than
forest. Collected ♀ & she had baby brood patch. Would
press 3rd bird was a full grown young essentially then
post-prio.molt.
Pairs
&
habitat
Except for this one group of 3 saw only pairs of birds
today. Flushed a lone bird from grass in power line cut.
It flew immediately back into than forest. Probably this species
uses the cleared areas for foraging & the ♂♂ come
to the edge frequently in the early morning to sing from
elevated song perches. But the core habitat for the species
is apparently the dense than forest.
♂ whisper
song
Pair came into "schuss" & down. Hand bird behind-⊖
giving very soft version of . - . - ....... song. Probably
soft enough to be a whisper song. Was repeated 5-10
times & then bird flew 10 feet & gave one more followed
immediately by regular volume version of same song. Did
not hear ♀ join in with any sort of vocalization. Collected ♂.
