“…For individuals capable of relatively large movements over short periods, moving, either temporarily or permanently, from dangerous environmental conditions seems like a successful strategy to improve the likelihood of survival (Hong et al. ). For example, onset of migration often occurs during periods of favorable weather conditions (Volkov et al.…”

Abstract. The increasing use of Bayesian inference in population demography requires rapid advancements in modeling frameworks to approach the rigor and flexibility of the current suite of maximum-likelihood models. We developed an unbiased, Jolly-Seber robust design (JSRD) model that is both accessible and generalizable in a Bayesian hierarchical multistate framework. We integrated band and age-classification data to estimate site entry, temporary emigration, and apparent survival rates, as well as estimate ageclass specific abundances. The complete model parameterization is provided in the Appendix S1, as well as tools for simulating capture histories and an assessment of model fit. We applied this model to determine whether these demographic processes in non-breeding population of American oystercatchers (Haematopus palliatus) were affected by a major hurricane event (Hurricane Matthew) in coastal Georgia. The JSRD model was demonstrably unbiased at relatively small sample sizes, and the majority of parameters were identifiable in the fully saturated model parameterization. In the model application, we found that Hurricane Matthew temporarily altered local population abundances of American oystercatchers through increased movements of individuals into and out of the observable population, but mortality rates were largely unaffected. Together, our results suggest that American oystercatchers were largely able to avoid the immediate demographic consequences (i.e., reduced survival) of Hurricane Matthew. Integrating age and band ratios from survey data allowed for more descriptive and potentially less biased estimates of age-specific abundance, relative to estimates generated solely from either mark-resight or survey data.

“…This increase in volume could consequently be an indication that birds may have been shifting their migratory routes away from directions that were adversely affected by wildfires, something that has at least been demonstrated in migratory geese during the same time frame (Overton et al 2021). It is not uncommon for bird movements on a given day to be affected by recent and proximate factors prior to flight (Chilson et al 2012, Streby et al 2015, Hong et al 2018, Overton et al 2021, Van Den Broeke and Gunkel 2021. This context is important particularly for migratory neotropical landbirds that can fly hundreds to thousands of kilometers on average in a night during migration (Wikelski et al 2003, Stutchbury et al 2009, Bayly et al 2013, Renfrew et al 2013, Gómez et al 2017.…”

Billions of birds annually migrate between breeding and nonbreeding grounds in North America. During fall 2020, there was a series of alarming mass-mortality events of migratory birds across the western United States, with estimates of 100,000 to 1 million birds having perished. One potential culprit behind these die-offs is wildfires, though there has been little research documenting the indirect effects of wildfires on actively migrating birds. We undertook a multi-year assessment of potential impacts that wildfires may have had on fall bird migration over the past decade, with a particular focus on fall 2020, using systematic bird banding data from southeastern Utah. We used a correlative approach to evaluate the relationship between estimates of acres burned by wildfires in western North America on several variables representing bird abundance and body condition. Notably, in our best fit models of birds banded at our research site during fall 2020, we found both a positive relationship for the number of bird captures and a negative relationship for body mass index with more daily burned acres. We provide an examination of incorporating lag effects of wildfires on different metrics of bird migration to account for potential impacts of fires on birds before migration and banding. Additionally, we assess the usefulness of different proxies of body condition in highly stressed land birds and introduce a scale for scoring emaciation of birds in the hand while banding. Our insights into avian migration ecology are one of the few studies that explore the role wildfires may have had in affecting migratory bird movements and health. Migration automnale d'oiseaux dans l'ouest de l'Amérique du Nord en période intense d'incendies de forêtRÉSUMÉ. Des milliards d'oiseaux migrent chaque année entre les aires de nidification et celles en dehors de la saison de nidification en Amérique du Nord. Au cours de l'automne 2020, une série d'évènements alarmants de mortalité massive d'oiseaux migrateurs a eu lieu dans l'ouest des États-Unis, l'estimation d'oiseaux ayant péri oscillant entre 100 000 et 1 million. Les incendies de forêt sont l'un des potentiels responsables de ces mortalités, bien que peu de recherches aient été menées sur les effets indirects de ceux-ci sur les oiseaux en migration active. Nous avons entrepris une évaluation pluriannuelle des impacts potentiels des incendies sur la migration automnale des oiseaux au cours de la dernière décennie, en portant une attention particulière à l'automne 2020, au moyen des données de baguage d'oiseaux dans le sud-est de l'Utah. Nous avons utilisé une approche corrélative pour évaluer la relation entre le nombre d'acres brûlés par les incendies de forêt dans l'ouest de l'Amérique du Nord et plusieurs variables décrivant l'abondance et la condition physique des oiseaux. Fait notable, nos meilleurs modèles, à partir des oiseaux bagués à notre site de recherche au cours de l'automne 2020, ont révélé une relation positive du nombre de captures d'oiseaux et une relation négative de ...
