The metazoan parasite community of migrating greater yellowlegs, Tringa melanoleuca, from the Rio Grande Valley, Texas and New Mexico.

Forty-eight migrant greater yellowlegs, Tringa melanoleuca, collected from southwestern Texas and southeastern New Mexico were examined for metazoan parasites. Nine helminth and 7 ectoparasite species were collected. Five new host records were recorded. The helminth fauna showed little diversity, little concentration for dominance, and no significant positive or negative associations between species were found. All species of helminths showed a contagious distribution. The component helminth community consisted of 2 core, 3 secondary, and 4 satellite species, and there was no host specialist. A checklist of metazoan parasites reported from greater yellowlegs in North America is included.
