Conducta alimentaria de cuatro especies de aves playeras (Charadriiformes: Scolopacidae) en Chametla, B.C.S., México

Feeding behaviour of four species for large shorebirds (Scolopacidae) was studied in a tidal mudflat, Chametla, Mexico, to determine the foraging efficiency of Limosa fedoa, Numenius phaeopus, Numenius americanus and Catoptrophorus semipalmatus in a stopover/wintering area; and their activity with t...
