Sphyrapicus varius nuchalis
Dry Lake, 15 mi. N. of Princeton, British Columbia
April 28 - 5:40 A.M. Overcast. Sapsuckers
were heard tattooing from all around the
lake, and occasional yelps were heard,
apparently when two birds came together.
I once saw three together, and there
was a chase. I guess there are about
four pairs, perhaps more, right around
the lake. All that I have seen are
typical nuchalis. The tattoos and calls
do not sound the least bit different from
those of the daggetti that I heard so
often last summer.
At about 6:30 A.M. the tattoos just
about ceased; only very occasionally was
one heard.
The tattooing birds (males?) are showing
interest in nest sites, as they pause
and look in when there happens to be
a hole in the tree near where their
noise-making is going on.
At 7:45 A.M., at Round Lake (south end)
about 1/2 mi. N. of Dry Lake, I came
across 2 sapsuckers (nuchalis) about
30 yds apart, each in the top of a
dead fir tree. One tattooed more often
than the other, but when the 2nd
one tattooed the first almost always
answered. This went on until just
after 8:00 A.M., when the 2nd bird
