Effectiveness And Utility Of Acoustic Recordings For Surveying Tropical Birds, Antonio Celis-Murillo, Jill Deppe, Michael Ward
Faculty Research & Creative Activity
Although acoustic recordings have recently gained popularity as an alternative to point counts for surveying birds, little is known about the relative performance of the two methods for detecting tropical bird species across multiple vegetation types. During June and July 2008, we collected species detection/nondetection data to compare the performance of a quadraphonic acoustic recording system and point counts for estimating species richness and composition and detection probabilities of 15 rare, moderately common, and common tropical bird species across six structurally distinct vegetation types (coastal dune scrub, mangrove, low-stature deciduous thorn forest, early and late successional medium-stature semievergreen forest, and …

Temporal Patterns In Fall Migrant Communities In Yucatan, Mexico, Jill Deppe, John Rotenberry
Temporal Patterns In Fall Migrant Communities In Yucatan, Mexico, Jill Deppe, John Rotenberry
Faculty Research & Creative Activity
We quantified temporal turnover in the composition of fall migrant landbird communities along the northern coast of the Yucatan Peninsula using Detrended Correspondence Analysis. The presence of winter residents of many migrant species at the site prevented turnover from being complete. However, early and late season transient communities shared few, if any, species in common. Point-count surveys showed greater compositional change than net surveys that included winter residents. The rate of species turnover was generally slow until the middle of the season, when it reached a maximum, and decreased again toward the end of the season as species composition began …
