Hermiet Thrush
Hastings Reservation
29 Nov Walked up to the Arnold with Laurie Drinkwater today,
stopping at the cabin to see what's been going on at the
spring. It has been quite dry all fall, with essentially no
rain. High overcast at about 1300 hrs. I was surprised to
see ~10 Hermit Thrushes congregating about, drinking!
Interesting, since this (1) suggests a method to catch and
band, and (2) leads to questions about winter spacing.
Presumably, they are territorial, and spring observation does
not reject this, since Pam had lots of separate Brown
Towhees at the spring. Also drinking at the spring were
many Golden-crowned Sparrows, J B Towhee. Some
aggression seen among the Hermit Thrushes, and I saw
as many as 6 gathering around the water tray at one
time.
15 Dec First big day of actually trying to work on these guys,
Thanks to Dave Winkler & Suzanne Morse, we've
set-up + ran some mist nets at the 2 water troughs along
S Hill. See reverse for net-set-up. Believe it or
not, 12 HT's captured + color banded (with stolen birds
from Pam). Best success came right at dusk.
Inspection of shit looked like birds have been
eating Madrone berries.
Aging -- According to the banding manual, 1st yr birds
should have "buffy shaft streaks" on 2o' coverts &
tertials. We found no birds like this, but about
half had buffy tips to those feathers, a characteristic
the banding manual said was unreliable. Still,
