“…Our estimated conditional band reporting probability determined from direct band recoveries of adult geese could be biased high if there was differential band loss or mortality between band types. The 1‐year band retention rates during this study were 98% for reward bands and 100% for standard bands, and were consistent with apparent band retention rates on a national scale during the same time (Zimmerman et al ). We found no pattern in the value of reward bands lost, but all of them were less than $100 in value.…”

Breeding populations of Canada geese (Branta canadensis) were established throughout western Colorado during 1955–1988 using geese transplanted from other areas. Subsequently, there has been no assessment of demographics and winter distributions on these local populations. Managers need this information to effectively manage breeding populations of Canada geese to provide publics with recreational opportunities and to reduce human‐goose conflicts in western Colorado, particularly for segments of internationally recognized populations with cooperative management plans. We conducted a band recovery study during 2000–2006 to assess demographics and winter distributions of Canada geese breeding in 7 subareas of western Colorado. Cooperators banded 19,189 geese during June and early July. We recaptured 5,185 of these geese 1–4 times during banding operations in subsequent years and most (97%) were recaptured in the subarea of banding the year after banding. We obtained 2,921 useable band recoveries through May 2007, and most (98%) recoveries were a result of either being shot or found dead during hunting season. Direct band recoveries (<1 year after banding) were recovered almost exclusively in Colorado (87%) and New Mexico (12%), and indirect band recoveries (≥1 year after banding) showed similar distribution (73% in Colorado and 16% in New Mexico). Geese in subareas of western Colorado had different recovery distributions, and contributed to 4 wintering concentrations of Canada geese in western and central Colorado and New Mexico. Annual survival probability for adult geese was 0.864 ± 0.012. The survival probability for juvenile geese was 0.503 ± 0.026, but we did find evidence that this estimate may be biased low. We used the band reporting probability of 0.525 ± 0.071 to derive harvest rates from band recovery rates. Harvest rate was 0.128 ± 0.018 for adult geese and 0.169 ± 0.024 for juvenile geese. Survival probability was lesser and harvest rate greater for the 3 western subareas (Western Plateau) compared to the 4 eastern subareas (Rocky Mountains). Our results suggest that Canada geese that breed and molt in western Colorado have high survival probability and are largely non‐migratory with some movement in winter from high to low elevation areas primarily in Colorado. To effectively manage the growing resident goose population in western Colorado, managers may need to increase harvest rates for these geese. © 2014 The Wildlife Society.

“…(1) that wearing a reward mark does not affect the likelihood of the animal being found; (2) that at some level the reward is high enough to encourage the finder to send back the information with an approximately 100% probability (Nichols et al 1991); (3) that the reward and standard rings have the same retention rates by birds (Zimmerman et al 2009a). Where these assumptions have been verified, such reward schemes have allowed estimations of the likelihood of a standard ring being returned (the value being around 30% in Mallard Anas platyrhynchos in the USA; Nichols et al 1991).…”

Changes in ring recovery rates over the last 50 years: shall we continue to ring ducks?

et al. 2010

Although knowledge of ring recovery rate is of crucial importance to establish demographic parameters, such as survival probability, this information is generally unknown for the dabbling ducks. The almost single existing value from the North American Mallard (Anas platyrhynchos) is thus generally applied to other species or geographic areas, even though this assumption may be strongly misleading. In the study reported here, we have relied on a proxy for actual ring recovery rate, namely, the proportion of rings fitted each year that were eventually reported, to test for differences between duck species (Mallard and Teal Anas crecca) and between countries [England (UK) and France] for Teal. Potential trends over time were also assessed. Ring recovery rate was found to have sharply decreased and at a similar rate over time in both species in France, and in both countries for Teal (e.g. from 22.7% in 1952 to 7.2% in 1992 for the British Teal). Teal rings were, however, reported more frequently than Mallard ones, and Teal rings were more frequently reported in the UK than in France. In recent years, a phone number for reporting the information has been included on the bird mark, with the immediate result of a doubling in the recovery rate in France. Adaptations to current ringing procedures that would improve ring reporting would appear to be necessary in the future if researchers are to keep ringing as a valuable source of information for bird demography studies.

“…() paired perishable plastic neck bands with steel leg bands assumed to be permanent to estimate retention of neck bands, Zimmermann et al. () paired standard leg bands with reward leg bands to assess retention of both types of bands through time, and Diefenbach and Alt () paired uniquely identifying ear tags with permanent tattoo marks to assess the retention of ear tags. For species where they are technically feasible, band‐retention studies can generate precise estimates of band loss.…”

Estimates of wear rates in metal bird bands, with applications for survival and movement models of marked individuals

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 rates have been determined. However, rapidly wearing bands may be over‐reported in the published literature relative to slowly wearing bands for two reasons. First, researchers publish reports of rapidly wearing bands as a warning to other researchers, but may not publish reports of bands wearing slowly. In addition, sampling error may result in over‐ or underestimation of wear rates. At the extreme, underestimates of wear rates may imply that bands gain mass while worn (i.e., have negative wear rates), whereas extreme overestimates look like rapid wear; only extreme underestimates, not extreme overestimates, are unpublishable due to their a priori implausibility. Hence, the existing literature on band‐wear estimates is likely upwardly biased relative to the true distribution of wear rates across species and band metals. Using routinely archived returned bands from the Australian Bird and Bat Banding Scheme for the period from 1963 to 2005, we estimated wear rates of bands applied to 173 species, five band metals, and 236 species/band size/band metal combinations. Band wear rates were generally well‐explained by band metal and species functional group, i.e., birds of prey, waterbirds (shorebirds, herons, and ibises), passerines, waterfowl (ducks, geese, and swans), rails, seabirds, parrots, and other non‐passerines, but some species had highly divergent wear rates compared to other species in their functional group. We also found that published estimates of wear rates were, on average, more rapid for a given metal type than determined from our analyses. We suggest that publication biases favoring publication of estimates of more rapid wear rates may drive the contrast between estimated wear rates in our analyses and published estimates.
