Francis H. Allen, in his notes, gives the two following graphic
accounts of the initial stage of the bird’s courtship: “April 10, 1904.
West Roxbury, Mass. I found two downy woodpeckers courting--at least, I
suppose that was what they were up to. They acted like mating flickers,
chasing each other about from tree to tree, keeping almost constantly
on the move and only pausing now and then to execute a sort of dance,
spreading their wings and tails. From time to time I heard from them a
long call resembling the flicker’s _whick, whick whick whick_, etc.,
but higher pitched than the flicker’s and, of course, not so loud. Less
often I heard another note--a softer, slighter, more hurried call,
similar in quality. I did not make out whether, these two calls were
made by different sexes, nor did I positively make out that the birds
were a pair, they kept in such constant motion. At least once one lit
crosswise of a twig. At last one flew off, and then the familiar and
characteristic long call of a downy sounded from another direction, and
the remaining bird flew over to the third bird, which was clinging to
the trunk of an elm. Then these two stayed in each other’s company but
did not conduct so elaborate a dance as the first couple.
“All this time a fourth bird had been drumming on a tree not far away.
I went up to the place and timed the drum calls, finding each roll to
last about two seconds. I could not count the taps, but thought they
numbered eight or ten to each roll. While I watched this bird, another
downy came along, sounding the flickerlike call, but rather faintly,
and the drummer flew to join her. They flew off together. I believe
it is only the male that drums, and I think it probable that the bird
that answered the drummer was the one that had taken part in the dance
before described, for that bird when she left her partner had flown off
in this direction.
“April 8, 1917. West Roxbury. Watched a pair courting this morning for
several minutes. Both sexes had a curious ‘weaving’ action, moving the
head and whole body from side to side on the tip of the tail as a pivot
with the neck stretched out and bill pointed on a line with the body,
and the whole body elongated. They did this both when clinging to the
side of a trunk and when on a horizontal or slanting branch. They were
silent but very active, flitting one after the other from branch to
branch and tree to tree, but making only short flights. The waving, or
‘weaving,’ motion of the head was rather rapid, perhaps two waves, that
is from left to right and back again, in about a second--but this is
stated from general impressions and memory only. These birds did not
spread the wings and tail as did the courting pair observed on April
10, 1904, and, as stated, they uttered no note.”
