but she may have removed them more often.
flights directed away from me when leaving the nest
would not allow observation of the fecal sac &
about 1/3 of the flights were in that direction. In
the four cases observed she flew away with her
load and landed with it, rather than dropping it
while in flight, a procedure common to rosy
finches.
I have heard young birds chirp only once in my
many visits to nests. On that occasion my presence
near the nest set them to stretching their necks &
chirping before we actually were in visual contact. On
a few other occasions they have been observed to
stretch their necks & peep for a moment when
being handled. Usually when handled they sit
quietly with legs tucked up against their bodies
& can be turned over, etc without the slightest
struggle or noise (unusual in my experience with
birds). Rosy Finch nestlings for example make much
more noise when fed & struggle more at all
ages when handled. They crawl out of a nest or
hide their heads when being approached. Perhaps
the "frozen" appearance of these ground nesters is
important to survival as a ground nester as
opposed to rosy finches who are out of reach of most
predators. I noticed the same freeze reaction
displayed by the Snow Buntings in nests
