Capsule The capture-recapture heterogeneity model M(h) can be used confidently to estimate species richness when using Breeding Bird Survey (BBS) data.
Aims To test the relevance of various probabilistic capture-recapture models for estimating species richness using data from large-scale, multi-observer monitoring schemes (e.g. BBS) sampling heterogeneous habitats.
Methods The program CAPTURE and its model selection algorithm were used to investigate the relevance of different capture-recapture models for estimating species richness within 601 BBS sampling units. We investigated whether the habitat in each sampling unit had any influence upon the model selected. We tested the efficiency of ...
