Banding allows identification of individual birds, and many investigators use data from recaptured or recovered birds to infer population parameters, including survival rates, migration rates, and recruitment rates. Such analyses often assume that band loss is negligible, but wear rates have been found to differ markedly among different band sizes, band metals, and species in the few cases where wear...
When comparing lifespan (longevity) between species, it is common practice to take the maximum recorded longevity value within each species as a proxy of maximum lifespan. Whether maximum recorded longevity is a reliable proxy of species' maximum longevity remains unclear. Some researchers correct for previously documented life history correlates of maximum recorded longevity before analysing new...
