La alimentación del Gorrion Común (Passer domesticus) en áreas de cultivo de regadío extremeñas

Abstract

Se describe el contenido estomacal de 142 Gorriones Comunes. La dieta es principalmente granivora. Durante la primavera-verano la diversidad trófica es máxima. Las semillas de seis plantas granívoras constituyen el 95,6 % de los elementos ingeridos, aunque el trigo y el maíz tienen mayor importancia desde el punto de vista de la biomasa. En otoño-invierno las semillas de Echinochloa crus-galli suponen alrededor de un 40 %, tanto en número como en peso, mientras que el trigo y el maiz sólo alcanzan, cada uno, un 20 % en peso

[EN] This note describes the food contents of 142 stomachs of House Sparrows (Passer domesticus). The diet is mainly granivorous. In spring-summer the trophic diversity is higher, the seeds of 6 weed specíes amounting to 95.6 % of the elements consumed, although the highest biomass proportions correspond to wheat and corn. In autumn-winter, the seeds of Echinochloa crus-galli constitute approximately 40 % both in number and weight, wheat and corn amounting each to 20 % in weight
