Quantitation of pyrethrum residues in brown tree snakes.

Carrion Seeking in Brown Tree Snakes: Importance of Olfactory and Visual Cues

We performed field experiments to examine brown tree snake (Boiga irregularis) attraction to carrion. These snakes were attracted to carrion and entered traps baited with dead mice as readily as traps baited with live mice. Using the cues arising from both live and dead prey, we examined the relative importance of visual and chemical cues to brown tree snakes. With carrion lures, chemical cues ...

Operational Control Of The Brown Tree Snake On Guam

An operational control program for brown tree snakes (Boiga irregulans) on Guam began in April 1993. The program focused on minimizing the dispersal of brown tree snakes to other Pacific islands and the U.S. mainland. During the first year of operation, more than 3,000 snakes were caught within a kilometer of high risk port facilities using traps, detector dogs, and spotlighting. Additionally, ...

Standardizing the evaluation of brown tree snake trap designs

The introduced brown tree snake has had devastating impacts on the native vertebrate fauna of Guam. Trapping is the primary means by which brown tree snakes are removed, either in support of reintroduction of endangered species or to deter their movement from Guam in cargo. Traps used to control brown tree snake populations have been continually evolving since the 1980s. Before general operatio...

Ontogenetic Shifts in Canion Attractiveness to Brown Tree Snakes (Boiga irregularis)

Impacts of the Brown Tree Snake: Patterns of Decline and Species Persistence in Guam’s Avifauna

Predation by brown tree snakes ( Boiga irregularis ) devastated the avifauna of Guam in the Mariana Islands during the last half of the twentieth century, causing the extirpation or serious reduction of most of the island’s 25 resident bird species. Past studies have provided qualitative descriptions of the decline of native forest birds but have not considered all species or presented quantita...
