AmphibiaWeb - Hyla avivoca


(Translations may not be accurate.)

Hyla avivoca (Viosca, 1928)
Bird-voiced Treefrog
Subgenus: Dryophytes
family: Hylidae
subfamily: Hylinae
genus: Hyla
Taxonomic Notes: Duellman et al. (Zootaxa 2016) treated two major clades as genera; AmphibiaWeb treats these two clades as subgenera(Hyla in the Old World; Dryophytes in the New World and East Asia), thus stabilizing traditional taxonomy.

The subspecies H. a. avivoca is found in the drainage systems of the Gulf coast and in the Mississippi River. H. a. ogechiensis occurs in the Atlantic coast drainage system. This frog is found discontinuously from Aiken, Barnwell and Allendale counties in South Carolina, west across Georgia and Alabama, in the panhandle of Florida and in suitable habitat in Mississippi. This species appears to be restricted to large-river swamps.
