Reportamos registros meritorios de Anous stolidus, Stellula calliope, Sphyrapicus varius, Myiopagis viridicata, Dendroica pensylvanica y Pheucticus ludovicianus del centro de Sinaloa. La mayoría de las aves fueron capturadas con redes de niebla. Aunque los registros parecen ser de individuos vagabundos, podría ser que la severa modificación del hábitat de la zona costera de Sinaloa esté facilitando la dispersión de algunas especies. La ausencia de registros previos de estas especies parece estar más relacionada con un bajo esfuerzo de observación que con incrementos en la distribución geográfica de las especies.
The Big Crested Mastiff Bat, Promops centralis (Thomas, 1915), is widely distributed from Mexico to South America but has yet to be reported in the state of Sinaloa, Mexico. We collected 122 acoustic recordings of P. centralis from tropical dry forest and agroecosystems in Sinaloa and Sonora for two years (2015 and 2016). We documented a new record for P. centralis outside the known distribution area in northwestern Mexico. Our results reveal that the current P. centralis distribution needs to be reevaluated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
