REBON-GALLARDO, Fanny; FLORES-VILLELA, Oscar  and  ORTIZ-RAMIREZ, David R.. Predation of nestling house finches (Haemorhous mexicanus) by a dusky rattlesnake, Crotalus aquilus, in Hidalgo, Mexico. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.2, pp.550-552. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2015.04.001.

For the first time, a case of predation on a Haemorhous mexicanus nest by the dusky rattlesnake Crotalus aquilus is presented. The phenomenon of gluttony by this rattlesnake, which may have caused the death of the snake is also documented; since it had already eaten an adult Peromyscus maniculatus before consuming the 4 chicks in the nest.

Keywords : Feeding; Gluttony; Predation; Viperidae; Fringillidae; Pygmy rattlesnakes; Montane rattlesnakes; Mexico.
