A map localities I heard crossbills, plus
the call type. I heard only Type 4
birds every place I found crossbills.
The traffic + people were very abundant
all along the coast.
I found probable nesting Type 4 birds
in tree groves among dunes at Honeyman
State Park. [Type 4].
I continued S along the coast,
checking for birds, but found less and
less as I drove S.
I camped near Whalehead Island on
private property above Hwy 101.

No crossbills were heard this morning,
although I was near good Sitka spruce
groves with abundant cones.
By 8:30 I began N again, explored
near Gold Beach & Port Orford -- found
no crossbills.
I finally found Type 4 birds at
Point Arago in Sitka spruce habitat.
Late in the day, I drove E into
the Cascades. The Doug Fir cone crop
was good only within 5-10 mi. of
the coast, thus inland was no
place for crossbills.
