The Cabo Rojo Salt Flats, at the southwestern tip ofPuerto Rico, provide important autumn stopover and winteringhabitat for migratory shorebirds. I studied the abundanceand distribution of shorebirds and their food resources atthis site during autumn of 1990 and 1991.Small calidrids (primarily Calidris pusilla and C.mauri) were the most abundant shorebirds at the salt flats.The maximum weekly counts of small calidrids in 1990 (2,690)and 1991 (3,532) occurred in mid October. Calidrids foragedprimarily in the Fraternidad lagoon system; roosting tookplace most often at the neighboring Candelaria Lagoon.The macroinvertebrate prey important to calidrids in theFraternidad system were Dasyhelea (Diptera), Trichocorixa(Hemiptera), and Artemia (Anostraca). Changes in invertebrateabundance coincided with fluctuations in salinity. (100 page document)
