Amphila quingustriata
July 14 / Brown Towhee + Canepon When also frase on ground
in this habitat, also Caetres When. All possible
competitors for 5-stripes.
behavin:
0700 - bird flown to rock outcrop Again very flopppy
flight at end. Sat again w/ tail cocked ~ 60°
very jerky jumping around - wing flit + tail jump.
Gave one sharp note & was joined by a 2nd bird
giving same movements. Two were & 2 put away,
bodies at vt-c, but facing each other. Then
disappeared over crest.
Amount of singing has decreased - mostly increased
quiet interval between song bouts.
forage
+ food:
0705 - watched pair foraging for 10± minutes. When I 1st seen
one bird (partly groom rectrix) had 2 inch caterpillar.
beat it against rocks, mandibulate from end to end, beat,
mandibulate, beat, & eat. Bill cope. Then hop 2- feet
and catch < 1 inch green caterpillar. This swallowed
w/ no preliminaries. Both members of pair spent
most of time foraging on ground. 50± % time in
legumes + other species. Much of time on rocky
outcrops. Food obtained here is questionable - at best
probably not many caterpillars.
8,16 social:
