GONZALEZ-ARRIETA, Rodrigo A.  e  ZURIA, Iriana. Aberrant coloration (partial leucism) in the house finch (Haemorhous mexicanus) in an urban area of central Mexico. Acta Zool. Mex [online]. 2015, vol.31, n.2, pp.318-320. ISSN 2448-8445.

We report the presence of a House Finch (Haemorhous mexicanus) with partial leucism in the city of Pachuca, Hidalgo. The individual was observed in two occasions interacting with other finches that had regular coloration. Pigment aberrations may help identify populations with genetic problems or populations facing chronic stress.
