This paper introduces a marginalized Bayesian Jolly Seber model that significantly improves computational efficiency for open population analysis, demonstrating speed gains of up to 1,000 times with minimal loss of accuracy.

The paper analyzes morphological changes in North American birds over time and space, finding that warmer temperatures correlate with smaller body sizes and increased wing length at higher elevations.

The paper shows migratory yellow warblers track climate niches by correlating wintering and breeding precipitation, with bill size linked to breeding season precipitation and population responses to rainfall.
