An interesting case of nest-protecting display is thus described by Dr.
Robert Cushman Murphy (1926):
She (assuming that it was the female) would allow us to come within
a few feet before leaving her well-concealed position. Then she
would spring from the nest, pitch on the ground close by, and,
standing with the tail toward us, would raise and spread it so as
to show to full advantage the double row of glistening white spots
at the ends of the rectrices and under coverts. Next, flashing this
striking banner slowly, she would move off among the trees in the
attitude of a strutting turkey cock, stopping when we refused to
follow, and then tripping ahead for a few steps, all the while
bleating softly. The effect was astonishing; the ordinary low
visibility of a woodcock against the forest floor no longer held,
for the spotted fan of the tail had become a most conspicuous and
arresting mark.
_Eggs._--The American woodcock lays four eggs, sometimes only three, and
rarely five. They vary in shape from ovate to rounded ovate and have a
moderate gloss. The ordinary ground colors vary from "pinkish buff" to
"cartridge buff" and in certain brown types from "pinkish buff" to
"cinnamon." They are usually rather sparingly and more or less evenly
marked with small spots, but sometimes these spots are concentrated
about the larger end. In the lighter types, which are the most common,
there are often many large blotches of light shades of "vinaceous drab"
or "brownish drab"; these are conspicuous and often predominate. Mixed
with them are numerous small spots of light browns, "cinnamon," "clay
color," or "tawny olive." In the brown types these spots are in richer
browns, "hazel," "russet," or "cinnamon brown," with the drab spots less
conspicuous. The measurements of 53 eggs, in the United States National
Museum, average 38 by 29 millimeters; the eggs showing the four
extremes measure =41= by =30= and =35= by =27.5= millimeters.
