摘要

The Virgin Islands Screech-Owl Otus nudipes newtoni is a little-studied taxon whose current status is uncertain. It historically occurred on several small islands immediately east of Puerto Rico in the Caribbean. In an effort to assess its current status, I carried out surveys on St. John, St. Croix, and St. Thomas, the three largest of the United States Virgin Islands. Acoustic and visual surveys were carried out nightly for a 3-wk period during August 1995. Playback recordings of owl calls from the Puerto Rico subspecies did not elicit any responses During surveys, nor did I see any owls. I conclude that this taxon is extinct, because the three Sampled islands contained the largest remaining patches of appropriate habitat for this spe- Cies.
