A survey of helminth parasites in 36 waterfowl species from the upper Lerma River, in central Mexico was conducted. A total of 20 helminth species were recorded, including 9 trematodes, 8 cestodes, 2 nematodes and 1 acanthocephalan. Six of the cestode species are recorded for the fisrt time from Mexican birds; the acanthocephalan Pseudocorynosoma constrictum is reported for the first time in Anas crecca, A. discors, Oxyura jamaicensis and Fulica americana. The highest prevalences were recorded for the cestodes Hymenolepis megalops and Sobolevicanthus krabbeella in Anas acuta, A. clypeata, A. cyanoptera and A. crecca.
