The range of the Texas woodpecker extends northward into southeastern
Colorado and southward into southern Tamaulipas. George Finlay Simmons
(1925) says that in Texas it is “rather general in distribution and in
choice of habitat; somewhat open post oak woods and oak upland gravel
terraces; mesquite forests; hackberry shade trees in town; mesquite
association pasturelands; open woods not far from water; marginal
timber along streams. In the hills, cottonwoods and oaks along stream
bottoms; wooded slopes of gorges. In winter, leafless city shade
hackberry trees.”
The Texas woodpecker is widely distributed and fairly common all over
Texas, except in the extreme eastern and extreme western portions;
it is a well known and familiar bird, just as our eastern downy
woodpecker is in the East; it is locally known as the “Texan sapsucker”
or “ladder-backed woodpecker.” Most of its habits are similar to
those of the cactus woodpecker, but it seems to enjoy a somewhat more
diversified habitat and is more inclined to forage and nest in larger
trees; it is not so strictly confined to the deserts and their environs.
_Nesting._--Mr. Simmons (1925) says that the nest is located from “4 to
25, average 12, feet from ground, in rotten stubs or dead and partly
decayed branches of oak, mesquite, hackberry, and willow trees, usually
alongside lake, river, creek, or ravine; when suitable trees are not
to be found, nests in cedar fence posts or telegraph poles along
roadsides; when in mesquite tree on mesquite-covered prairie, entrance
of cavity on under side of low, drooping limb. * * * Entrance diameter
1.50. Depth of cavity 7 to 8, rarely 10.”
_Eggs._--The Texas woodpecker lays 2 to 6 eggs, Usually 4 or 5,
rarely as many as 7. These are indistinguishable from the eggs of
the cactus woodpecker. The measurements of 51 eggs average 20.50 by
15.83 millimeters; the eggs showing the four extremes measure =22.86=
by 15.75, 20.32 by =17.02=, =17.27= by 15.49, and 19.05 by =14.73=
millimeters.
_Food._--Mr. Simmons (1925) says that it “searches high up on the
knotty trunks of oak trees in open groves for larvae and eggs of
injurious wood-boring insects, for the adults of similar as well as
other insects, and for weevils and ants.”
_Voice._--Simmons (1925) says that this is “usually a thin,
high-pitched, shrill _cheek_; _tcheek, queep_ or _queep-queep_,
uttered as the bird gives a hop in its progress up the
tree-trunk. Sometimes an incredibly rapid, shrill, ringing, even,
not-so-high-pitched _cheeky-cheeky-cheeky-cheeky-cheeky_ or
_tchee-dee-dee-dee-dee-dee-dee-dee-dee-deet_; less commonly, _chickp,
chickp, chick-chick-chick-chick-chick-chick-chick-chick_. Drums rapidly
with its bill on dead limb of tree at any time of year.”
DISTRIBUTION
_Range._--Southwestern United States, Mexico, and British Honduras;
nonmigratory.
