Migration distances of shorebird species correlate with life history strategies. To assess age-specific migratory preparation and adult wing-molt strategies, we studied Western Sandpipers (Calidris mauri) and Semipalmated Sandpipers (C. pusilla)[...]

The digitalization of museum collections and concurrent increase in citizen-science initiatives is ushering in an era of unprecedented availability of primary biodiversity data. These changes permit a reappraisal of phenological patterns of trop[...]

Population age structure and vital statistics are important for understanding songbird demography and for developing conservation strategies. Field-based estimates of survival rates based on mark–recapture methods are conservative because they a[...]
