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
