Color aberrations in Mexican birds: A review and new records from San Luis Potosi [Aberraciones cromáticas en aves de méxico: una revisión y registros recientes en el estado de san luis potosí]

Color aberrations in birds have attracted the attention of researchers for a long time. Mexico has seen a recent increase in articles published on this subject. Here, we conducted a comprehensive review of the literature published on the topic of chromatic abnormalities in Mexico. Additionally, we report new records of chromatic aberrations in the plumage of four species Eurasian Collared-Dove (Streptopelia decaocto), Canyon Towhee (Melozone fusca), Worthen?s Sparrow (Spizella wortheni), and House Sparrow (Passer domesticus) based on 10 years (2007-2017) of observations in the state of San Luis Potosí, Mexico. Based on the literature review and on our data from this study, we show that there are reports of chromatic abnormalities for Mexico in 31 species belonging to 22 families. Family Icteridae presented the greatest number of cases for the following species: Red-Winged Blackbird (Agelaius phoeniceus), Great-Tailed Grackle (Quiscalus mexicanus), Bronzed Cowbird (Molothrus aeneus), and Brown-Headed Cowbird (Molothrus ater). For other six families, we recorded two species with chromatic aberration records (Columbidae, Cuculidae, Rallidae, Scolopacidae, Tyrannidae, Emberizidae). © Neotropical Ornithological Society.
