Range DescriptionXenornis setifrons occurs locally in east Panama and north-west Colombia. Twelve sites are known in the Serranías de San Blas, Darién, Tacarcuna (Panama) and Baudó (Colombia) (Adsett and Wege 1998). There is also an unverified report from a relatively well-known site in the Serranía de Pirre, Panama (Engleman 1993, G. R. Angehr in litt. 1998). Its distribution is inexplicably patchy, with gaps in apparently suitable areas of habitat (Adsett and Wege 1998). Surveys in 1992 found it fairly common (although difficult to detect) at Nusagandi, San Blas (P. G. W. Salaman in litt. 1999). It has not been reported from east San Blas or Darién since 1964 (Adsett and Wege 1998), possibly reflecting a dearth of fieldwork. However, in the west, a number of new populations were discovered during the 1990s (Adsett and Wege 1998). In Colombia, two specimens were collected in 1940 in the Serranía de Baudó, but recent surveys on the west slope have not found the species (P. G. W. Salaman in litt. 1999).
