Frogmouths (Podargidae)

Short-tailed Frogmouth (Batrachostomus poliolophus) - HBW 5, p. 286

French: Podarge à tête grise German: Graukopf-Froschmaul Spanish: Podargo Colicorto
Other common names: Pale-headed Frogmouth; Bornean/Sharpe’s Frogmouth (mixtus)

Taxonomy: Batrachostomus poliolophus Hartert, 1892, Padang, West Sumatra.
Race mixtus has often been regarded as a separate species, an arrangement apparently initiated in 1937 by cautious uncertainty expressed regarding the characters of the then unknown male of the nominate form. Subsequent to the latter being described in 1938, the two forms seem not to differ greatly in coloration of either sex, and the extreme measurements of each closely approach those of the other, so that their treatment as races of the same species would seem more appropriate; possible differences in vocalizations, however, require investigation. Two subspecies recognized.
