Survival rate estimation in the presence of tag loss using joint analysis of capture-recapture and resighting data Survival rate estimation in the presence of tag loss using joint analysis of capture-recapture and resighting data
Studies using resightings of marked birds typically make use of readily-observable tags that are not retained as well as metal legbands. We review methods for estimating survival rate with open capture-recapture / resighting models when tag loss is not negligible. All methods rely on data from double-banding studies, usually carried out as part of the resighting study by application of...

The 'robust' capture-recapture design allows components of recruitment to be estimated The 'robust' capture-recapture design allows components of recruitment to be estimated
The 'robust' capture-recapture design (Pollock 1982) allows analyses which combine features of closed population model analyses (Otis et aI., 1978, White et aI., 1982) and open population model analyses (Pollock et aI., 1990). Estimators obtained under these analyses are more robust to unequal catch ability than traditional Jolly-Seber estimators (Pollock, 1982; Pollock et al., 1990...

The estimation of exchanges among populations or subpopulations The estimation of exchanges among populations or subpopulations
Capture-recapture methods for estimating rates of immigration, emigration, and movement among geographic strata are reviewed. We discuss likelihood-based estimation methods under models incorporating Markovian and non-Markovian movement. We briefly describe a computer program developed by Brownie et al. (1992) to carry out the necessary estimation and testing.

The influence of capture-recapture methodology on the evolution of the North American Bird Banding Program The influence of capture-recapture methodology on the evolution of the North American Bird Banding Program
Capture-recapture methodology has advanced greatly in the last twenty years and is now a major factor driving the continuing evolution of the North American bird banding program. Bird banding studies are becoming more scientific with improved study designs and analytical procedures. Researchers and managers are gaining more reliable knowledge which in turn betters the conservation of...
