The Marismas Nacionales wetland system (Nayarit, Mexico) is a Site of International Importance as designated by the Western Hemispheric Shorebird Reserve Network. The American Avocet (Recurvirostra americana) is one of the most numerous shorebirds in the area; nevertheless, there is little information about its overwintering stay at Marismas Nacionales, despite part of the site being decreed as a Biosphere Reserve. In order to clarify some aspects of American Avocet winter ecology, we used transects and scanning sampling method during the winter: to determine distribution and abundance in the Marismas Nacionales (2010-2011), as well as density and population structure in one of the sectors of the Biosphere Reserve (2011-2013). The American Avocet win­tering population in the Biosphere Reserve was calculated to be about 26,000 individuals (5.7% of the world’s population), but approximately 36% of avocet wintering population in Marismas Nacionales was outside of the reserve, also there was a certain preference for some wetlands. Evidence suggests that spring migration starts during the first weeks of March. We observed some spatial segregation between sexes, but our results, although valid, are inconclusive because of difficulties in sexing individuals in the field. In spite of local changes in these wetlands, American Avocet winter population has apparently been relatively stable over the last twenty years. Therefore, Marismas Nacionales remains a key wetland for American Avocet in North America.

Recurvirostra Americana

Records are presented of 11 species of parasitic helminths recovered from 37 American avocets. Birds were collected in Kansas and Colorado from April 1973 to August 1974. Parasites found included 3 trematodes, 2 nematodes, 1 acanthocephalan and 5 cestodes, 4 of which are new species. Hymenolepis cervotestis sp.n. (Hymenolepididae) is described from the small intestine of 7 avocets. It exhibits extreme protandry with the testes appearing before external segmentation is evident. Sobolevicanthus coloradensis sp.n. (Hymenolepididae) is described from the small intestine of 4 avocets. This species is found to have its scolex embedded in the intest-tinal mucosa of its host. Diorchis recurvirostrae sp.n. (Hymenolepididae) is described from specimens recovered from the small intestine of 5 avocets. Diplophallus coili sp.n. (Acoleidae) is described from the small intestine of all 37 avocets. The family Diploposthidae is suppressed and the family Acoleidae is emended to include the 4 genera previously placed in Diploposthidae. A key to the genera of Acoleidae is presented.
