Diurnal Predation by a Coyote (Canis latrans jamesi) on an Adult Blue-Footed Booby (Sula nebouxii) on Isla Tiburón, Gulf of California, Mexico

We report the predation by a coyote (Canis latrans jamesi) on a foraging, adult blue-footed booby (Sula nebouxii) during the early afternoon on 2 December 2009 on the west coast of Isla Tiburón in the Gulf of California, Mexico. The observed event took place while a flock of blue-footed and brown boobies (Sula leucogaster) was plunge-diving close to shore. The food habits of coyotes on Isla Tiburón are not known, and capture of live adult boobies by coyotes has not previously been documented in the literature.

Management Implications of the Biodiversity and Socio-Economic Impacts of Shrimp Trawler By-Catch in Bahía de Kino, Sonora, México

The shrimp fishery is the most economically important fishery in Mexico. The trawler-based portion of this fishery results in high rates of by-catch. This study quantifies and describes the biodiversity of by-catch associated with trawling in the Bahía de Kino region of Sonora, Mexico. Data were collected from 55 trawls, on six boats, over 14 nights, during November of 2003, 2004, 2006–2009. By-catch rates within trawl samples averaged 85.9% measured by weight.
