Another fledgling. Some cool behaviors to note here: (1) that slowly delivered AMGO-like contact note of dependent young in this species (ts'wee!); (2) the high, thin, rapid, weak, ventriloquial chittering that seems to be a solicitation vocalization; (3) the abortive effort at flycatching-while-perched; (4) the highly stereotyped orange-gape-display of the fledgling; and (5) despite the bird's youth, its well-expressed tail-dipping.
观察细节
Outnumbered all other birds, combined, out there. Two family groups, plus at least two more distant (calling) adults. See annotated media below.
