Sandhill Crane Surveys In The Northern Interior Highlands Of Mexico, Roderick C. Drewien, Wendy M. Brown, Elwood G. Bizeau
Proceedings of the North American Crane Workshop
Most sandhill cranes (Grus canadensis) wintering in Mexico are found in the northern Interior Highlands of Chihuahua. We surveyed sandhill cranes in the states of Chihuahua and occasionally Durango, Mexico, in winters 1972-90. The population averaged 23,106 (SD = 10,369) in 11 counts at 5-6 areas in Chihuahua. Laguna de Babicora, the most important wetland for cranes wintering in Mexico, had the largest numbers (X = 16,012), followed by Ascension (x = 2,405) and Laguna de los Mexicanos (x = 1,468). All 3 migratory subspecies were present. The lesser subspecies (G. c. canadensis) comprised 85.7% of …

Gulf and Caribbean Research
Eight species of Excorallana, E. acuticauda, E. delaneyi, E. oculata, E. sexticornis, E. subtilis, E. tricornis tricornis, E. warmingii, and Excorallana sp. are recorded for the eastern coast of Mexico. The range of E. delaneyi is extended south in the Gulf of Mexico. Excorallana oculata and E. subtiIis are reported for the first time in the Gulf. Based on specimens from the east coast of Mexico, a supplemental description of E. subtilis is presented and its taxonomy to other closely related species discussed. A key is provided to the adult males of …
