Resumen


El gorrión chapulín (Ammodramus savannarum) se distribuye ampliamente en las llanuras de América del Norte durante la temporada de reproducción, con poblaciones de cuatro subespecies clasificadas como residentes, migratorias y parcialmente migratorias. En México y América Central, la distribución del taxón especie es poco conocida, especialmente en lo que respecta a las poblaciones reproductoras. Sólo hay un registro de reproducción para las praderas del norte de México en el estado de Zacatecas desde mediados de la década de los cincuenta. Durante la temporada de reproducción de verano de 2017 registramos, con la ayuda de la atracción de vocalizaciones, seis individuos de gorrión chapulín en una pradera del norte de Durango, dos de los cuales respondieron activamente al llamado, las aves realizaron comportamiento territorial además del hallazgo de un nido activo con cuatro polluelos. Este es el primer registro reproductivo de verano para el estado de Durango en Cuchillas de la Zarca, 80 km al sur de la ciudad de Parral, Chihuahua, un área prioritaria de conservación de pastizales de América del Norte.

Palabras clave


Ammodramus savannarum; actividad reproductiva; aves de pastizal; hábitat reproductivo; rango reproductivo.
