Catharus sp.—ThrushesPleistocene regional distribution of Catharus sp

Swainson's Thrush apparently is not common in the region, though present (Ligon 1961). In light of limitations of comparative material, the identification from Dry Cave as C. swainsoni is iffy, and I have changed the 1989 unqualified identification to "?".

Sites.

Late Wisconsin: Harris' Pocket (Harris 1989 as C. swainsoni, but now considered ? Catharus).

Literature. Harris 1989; Ligon 1961.

This thrush is widespread in our region either as resident or migrant (Mead et al. 1984).
