M. Legare, W.R. Eddleman, P. A. Buckley, C. Kelly
1999, Journal of Wildlife Management (63) 116-125
Tape playback is often the only efficient technique to survey for secretive birds. We measured the vocal responses and movements of radio-tagged black rails (Laterallus jamaicensis; 26 M, 17 F) to playback of vocalizations at 2 sites in Florida during the breeding seasons of 1992-95. We used coefficients...
Estimating transition probabilities in unmarked populations: Entropy revisited
E.G. Cooch, W.A. Link
1999, Bird Study (46) S55-S61
The probability of surviving and moving between 'states' is of great interest to biologists. Robust estimation of these transitions using multiple observations of individually identifiable marked individuals has received considerable attention in recent years. However, in some situations, individuals are not identifiable (or have a very low recapture...

R.J. Cooper, R.R. Wilson, G.D. Zenitsky, S.J. Mullin, J.D. Dececco, M.R. Marshall, D.J. Wolf, Lars Y. Pomara
1999, Condor (101) 920-923
In response to the critique by Schmidt and Whelan (Condor 101(4):916-920, 1999), we find that the relationship between nest success and tree selectivity is dependent upon inclusion or exclusion of particular tree species, whether or not years are pooled, and the selectivity index used. We question their use of...

Program RDSURVIV: An estimation tool for capture-recapture data collected under Pollock's robust design
W. L. Kendall, J.E. Hines
1999, Bird Study (46) S32-S38
Several papers have demonstrated the advantages of collecting capture- recapture data using subsamples (i.e. Pollock's robust design). Compared with a standard design (i.e. one sample per period), this approach (1) permits the estimation of more demographic parameters and (2) in many cases produces more efficient estimators. Program SURVIV is a...
