| Popis: | Little is known about the current status of raptor populations in tropical Mexico. From 2008 to 2010 we studied resident diurnal raptors in the region of Los Tuxtlas, Veracruz. We surveyed forest habitats with different levels of conservation to confirm current raptor presence and to measure relative abundance. We found only 18 of the 24 species of resident raptors reported in the literature still present. Of the family Accipitridae, Gray-lined Hawk (Buteo nitidus) was the most abundant species, with an average rate of 0.20 individuals/km covered. Of the Falconidae, Crested Caracara (Caracara cheriway) was the most abundant, with 0.09 individuals/km. Species associated with forest habitats such as White Hawk (Pseudastur albicollis), Ornate Hawk-Eagle (Spizaetus ornatus), Black Hawk-Eagle (Spizaetus tyrannus), and Barred Forest-Falcon (Micrastur ruficollis) were observed infrequently, and exclusively in well preserved fragments of tropical rainforest and cloud forest. We believe that the main caus... |
