and my wish to secure a setting of eggs before departing
seemed in a fair way of being fulfilled. Strolling among
the cypresses on the 27th of March, I found four trees upon
which the birds were at work or had been recently, and in
such cases the birds themselves were always to be found in
the immediate vicinity. Passing a half-dead tree I heard
the sounding taps of a woodpecker at work, and as I neared
the spot, the slight noise which I made as I carefully
picked my way over the rock-strewn ground caused a handsome
male bird to suddenly appear at an opening about four feet
high. With a foot grasping either side of the entrance he
gazed upon the intruder. Having comprehended the situation,
he flew to another tree, where he quietly awaited my
inspection and departure. The hole was then down about
fifteen inches. By April 7, it had reached a depth of about
twenty inches and contained six fresh eggs, upon which the
female was then sitting.
Mr. Brown collected, for the Thayer Museum, six sets of eggs, one set
of five, two sets of four, one set of three, and two single eggs, all
of which are now in the Museum of Comparative Zoology in Cambridge,
Mass. The eggs were collected on dates ranging from May 8 to June 8,
1906; the nests were all in cypresses, mostly old or dead trees or
stumps, at heights ranging from 4 to 20 feet above the ground, and
at altitudes of from 3,700 to 4,500 feet above sea level; one of the
cavities was only 2 inches deep, but some of the others were 18 or 20
inches deep and from 3½ to 4 inches in diameter.
_Eggs._--The number of eggs laid by the Guadalupe flicker apparently
ranged from four to six. The eggs that I have seen, in Cambridge, are
ovate, pure white, and decidedly glossy, like other flickers’ eggs.
The measurements of 23 eggs average 27.8 by 21.7 millimeters; the eggs
showing the four extremes measure =30.2= by 21.1, 28.0 by =22.5=, and
=26.8= by =20.5= millimeters.
_Food._--Mr. Bryant (1887) says: “The food of this species during a
portion of the year consists largely of smooth-skinned caterpillars,
besides numerous beetles and ants; the latter are always obtainable and
growing to a large size figure as an important item of their diet.”
_Behavior._--He also remarks: “Of all the species of this family I
have ever met with, none have been so tame and unsuspicious or less
frightened by the report of a gun.”
_Voice._--The notes of the Guadalupe flicker are also similar to those
of the mainland forms, for Mr. Bryant (1887) says: “In addition to
the familiar scythe-whetting notes they have the peculiar ‘wake-up’
call and its rapid prelude of monosyllables. By imitating this call I
decoyed a distant female to within short range, the bird coming through
the thickest of the cypress grove, stopping at short intervals to call
and listen for a reply.”
