ResumoOn 20 March 1985, between the towns of Venustiano Carranza and Magallanes in the 10s Tuxtlas mountains near Volcan Santa Marta (18"19' N, 94"96' W) we encountered a farmer that had killed an Ornate Hawk-Eagle (Spizaetus ornatus).This bird was shot at the edge of the forest in a disturbed area with grass and secondary vegetation, at approximately 200-m above sea level.The vegetation in this region is named "Bosque Tropical Perennifolio" (Rzedowski 1978) (tropical evergreen forest).This specimen was a male that weighed 1,150 g.Stomach contents included feathers and bird bones.Based on the dimensions of wing bones (ulna and radius), trachea rings, and the color and form of the feathers, we suspect the prey was a Melodious Blackbird (Dives dives).Furthermore, we found two species of ectoparasites on the eagle' s feather, one was a mallophagan, Menacanthusstramineus, that feeds on pieces of feathers and scales of skin.The other parasite was a blood-sucking fly (family Hippoboscidae) Pseudolynchia canariensis (Ross et al. 1982).During our previous field work from 2 to 20 March 1985 we saw and heard what we believed was an eagle flying and calling several times over the canopy of the forest.These observations occurred in the Santa Marta Volcano, at about 860 m above sea level at the edge of tropical evergreen forest and mesophilus forest (Rzedowski 1978).The Ornate Hawk-Eagle is uncommon in Mexico.where it is a resident in tropical and subtropical zones of the states of Tamaulinas.Veracruz.San Luis Potosi.Puebla, Oaxaca, Chiapas, duintana Roo, Yucatan, and Colima (Friedmann et al. 1950, Iiiigo 1984).It is possible that the range extends to Campeche, Tabasco, Guerrero, and the hills of the west coast of Michoacan but no records are known.This eagle inhabits evergreen tropical forest (tropical rain forest), the edges of mesophyllous forests (cloud forest), tropical deciduous forest (deciduous seasonal forest), and sometimes the edge of open areas like grasslands
