Range. — Southern Mexico to Cayenne, southeastern Brazil, Bohvia, and Ecuadór. (About twelve species.[1])
KEY TO THE SPECIES AND SUBSPECIES OF DENDROCOLAPTES.
a. Pileum barred or transversely lunulated with black. (Dendrocolaptes sanctithomæ.)
- b. Pileum distinctly more rufescent or tawny than color of back; back more broadly or more distinctly barred; bars on under parts broader. (Southeastern Mexico to western Panamá.)
Dendrocolaptes sancti-thomæ sancti-thomæ (p. 229).
- bb. Pileum nearly (sometimes quite) concolor with back; back more narrowly or less distinctly barred; bars on under parts narrower. (Southwestern Costa Rica and adjacent part of western Panamá.)
Dendrocolaptes sancti-thomæ hesperius (p. 232).
aa. Pileum streaked with buffy or whitish.
- b. Pileum blackish, with narrow (and indistinct?) buffy streaks; chest with pale buffy or whitish predominating (the mesial streaks broader). (Guatemala.)
Dendrocolaptes puncticollis (p. 232[2]).
- bb. Pileum grayish brown, with broader and more distinct streaks; chest with brown predominating, the buffy mesial streaks narrower. (Dendrocolaptes validus.)
- c. Chest more distinctly and regularly streaked; under parts less extensively barred. (Colombia, etc.)
Dendrocolaptes validus validus? (extralimital).[3]
- cc. Chest less distinctly or more irregularly streaked (the streaks broken along edges by black dots or bars) and under parts more extensively streaked. (Costa Rica and Panamá; Nicaragua?; northwestern Colombia?).
Dendrocolaptes validus costaricensis (p. 233).
DENDROCOLAPTES SANCTI-THOMÆ SANCTI-THOMÆ (Lafresnaye).
BARRED WOODHEWER.
Adults (sexes alike). — Pileum and hindneck dull cinnamon-rufous or russet marked with crescentic bars or lunules of black; back, scapulars, and smaller lesser and middle) wing-coverts olive-brown (nearly raw-umber to mars brown), barred, more or less distinctly, with black; rump, upper tail-coverts, tail, and proximal secondaries deep cinnamon-rufous or chestnut (the tail usually darker, more chestnut, than other parts), the shafts of rectrices darker; primaries and distal secondaries deep cinnamon-rufous edged, more or less
broadly, with grayish brown or oUve, the inner webs of longer primaries
- ↑ Of these the following have been examined in this connection: D. picumnus Lichtenstein, D. validus Tschudi, D. certhia (Boddaert), D. obsoletus Ridgway, D. radiolatus Sclater and Salvin, and D. sancti-thomæ (Lafresnaye).
- ↑ I have not seen a specimen of this form, and, as stated on p. 233, the published descriptions do not clearly indicate the differences from D. validus.
- ↑ Dendrocolaptes validus Tschudi, Fauna Peruana, Aves, 1845, 242, pl. 21, fig. 2 (Peru); Sclater, Cat. Birds Brit. Mus., xv, 1890, 172, part. — Dendrocolaptes multistrigatus Eyton, Jardine's Contr. Orn., 1851, 75 (locality not indicated; coll. Derby Mus.).
I have not seen a Peruvian specimen of this species, and am therefore not at all sure that the Colombian specimens (chiefly from the Santa Marta district), with which I have compared Costa Rican examples, are subspecifically the same.
