Curvebill Thrasher

Toxostoma curvirostre curvirostre

The short wings and long, tilting, tail of this bird gives it the characteristic Thrasher flight among the sparse bushes and deserts of its habitat. Its two syllabled liquid call is a dominant note and its song one of the richest in the naborhood. They feed on fruit and ground insects which seem to make them immune to thirst. —Bailey.

BREEDING

NEST: Built of thorny twigs lined with grass and rootlets and located in bush cactus, tall yuccas or thorn brush.

EGGS: 3–4; pale bluegreen minutely speckled all over with brown.

RANGE

Southeastern New Mexico, to Rio Grande valley and southern Gulf coast of Texas.

Palmer Thrasher

Toxostoma curvirostre palmeri

Finley could only distinguish PALMER from Bendire by the larger nest! Bradford Torrey solved the difficulty by difference in size of the bills. Students should keep these two points in mind when identifying the birds (?).

BREEDING

NEST: Large and bulky platform of sticks with grass lining, usually placed in cholla cactus.

EGGS: Similar to those of Curvebill Thrasher.

RANGE

West Central Arizona and southwestern New Mexico.
