June 16. I walked up the new road toward River Glen.
(10 minute) Sh.Sh.Hawk - one, flying; Ash.Thr.Flycatcher 1,
Wren-at 1, Chipping Sparrows 2 pr., Hermit
Thrush. (5 sp. added). Tanager at Hurlingtons-
On the way home, I stopped at the top of Swan
Copa Grade where I added the Thrasher and
Hutton Vires. The most abundant birds were
Purple Finches all singing. Do males court
predate in good feeding areas during nesting
reason?
Total species seen: 29+3+6+5+2 = 45sp.
The Purple Finches at our place were feeding
on the seeds of the ceanothus - A male
showing no red ate six or eight seeds, sang;
at more seeds, sang; ate, sang; ate, sang.
I was watching a baby thrush perched in
a dense hazel at the top of the river bluff at
Joy Camps. It took me a long time to find him
though he was calling constantly - a throaty
call with a suggestion of thrush quality.
I could see only his back. I thought if I
imitated the thrush whistle he might turn
toward me. He did instantly and when I
whistled a second time he flew directly toward
me, dodged me by about two feet and alighted
on the ground behind me. When I whistled
again he ran toward me. I went away
as his mother would come and feed him.
