Summary

Visual survey data for brown treesnakes from caves with and without swiftlets. Each record (line) represents the snake sightings that occurred during a block of time, typically 1 hour at one site by searcher(s) during one search (i.e. one date). Snakes removed from caves and adjacent areas during visual surveys were then necropsied. Each record (line) represents necropsy results for a given individual.

Purpose

Mariana swiftlets are of conservation concern because it is one of the last species of native forest birds breeding in the wild on Guam and is listed as Endangered under the U.S. Endangered Species Act (U.S. Fish and Wildlife Service 1984). Although multiple factors may have contributed to the decline of swiftlets on Guam, brown treesnakes in caves may be limiting recovery.
