Aug 29 Willow Creeks 400 ft. Humboldt B., Calif.
1 bird collected from a Blackberry (Rubus
recursans) tangle around a clump of
marrow-leaved willows (Salix hindsiana).
It was seen eating ripe blackberries a
short time before it was taken. At least 1
more bird was heard in adjacent blackberry
tangles.
Aug 31 same locality - Both today and yesterday
I found quite a number of chats in the
Blackberry tangles along the little stream
running from the highway to the
Trinity River. There must be at least
one bird in every 200 square feet of
this habitat, amounting to a total
population for this area of 20 to 30 birds.
They seem to be busily feeding on
the ripe berries in these tangles.
