Tracking repeat migratory journeys of individual animals is required to assess phenotypic plasticity migration behaviour in space and time. We used light-level geolocators track the long-distance songbirds (wood thrush, Hylocichla mustelina), and, for first time, individuals. compare between- within-individual variation examine flexibility timing route spring autumn. Date departure from wintering sites Central America, along with sex age factors, explained most (71%) arrival date at North...
Each autumn billions of songbirds migrate between the temperate zone and tropics, but little is known about how events on breeding grounds affect migration to tropics. Here, we use light level geolocators track wood thrushes Hylocichla mustelina test for first time if late moult poor physiological condition prior delays arrival winter territory. Late nesting postponed feather moult, birds with less advanced in August were significantly farther north 10 October while en route Individuals...
Abstract Many migratory animals are experiencing rapid population declines, but migration data with the geographic scope and resolution to quantify complex network of movements between breeding nonbreeding regions often lacking. Determining most frequently used routes for a species is critical understanding dynamics making effective conservation decisions. We tracked individual Wood Thrushes (Hylocichla mustelina) (n = 102) from across their range light‐level geolocators and, first time,...
The rapid pace and potentially irreversible consequences of global change create an urgent need to predict the spatial responses biota for conservation better inform prioritization management terrestrial habitats prevent future extinctions. Here, we provide accessible entry point field guide near-future work building predictive species distribution models (SDMs) by synthesizing a technical framework proactive avian biodiversity. Our offers useful approach navigate challenges surrounding...
Predictable seasonal changes in resources are thought to drive the timing of annual animal migrations; however, we currently understand little about which environmental cues or tracked by different migratory bird species across planet. Understanding birds track multiple systems is a prerequisite developing generalizable conservation plans for changing global environment. Within New World, climatic differences experienced Nearctic–Neotropical (NNM; i.e. breed North America and spend...
Behavioral flexibility, the ability to adapt behavior new circumstances, is thought play an important role in a species’ successfully environments and expand its geographic range. However, flexibility rarely directly tested way that would allow us determine how works predict their environments. We use great-tailed grackles (Quiscalus mexicanus; bird species) as model investigate this question because they have recently rapidly expanded range into North America. attempted manipulate grackle...
Behavioral flexibility should, theoretically, be positively related to behavioral inhibition because one should need inhibit a previously learned behavior change their when the task changes (flexibility). However, several investigations show no or mixed support of this hypothesis, which challenges assumption that is involved in making flexible decisions. We tested hypothesis (reversal learning and solution switching on multi-access box by Logan et al., 2022) associated with (go/no go...
Fork-tailed Flycatchers (Tyrannus s. savana) breed from central to southern South America September January, migrating northern spend the non-breeding season. However, little is known of migratory routes, rate, and timing migration those that in Brazil. In 2013, we attached light-level geolocators breeding Sao Paulo State. Data for six male flycatchers recaptured 2014 indicates they exhibited two fall strategies. Some individuals migrated northwest wintering grounds (primarily Colombia,...
Behavioral flexibility, the ability to change behavior when circumstances based on learning from previous experience, is thought play an important role in a species successfully adapt new environments and expand its geographic range. It alternatively or additionally possible that causal cognition, understand relationships beyond their statistical covariations, could significant rapid range expansions via learn faster: cognition lead making better predictions about outcomes through exerting...
The ability of other species to adapt human modified environments is increasingly crucial because the rapid expansion this landscape type. Behavioral flexibility, change behavior in face a changing environment by packaging information and making it available cognitive processes, hypothesized be key factor species’ successfully new environments, including expand its geographic range. However, most tests hypothesis confound behavioral flexibility with specific proxy aspect foraging, social, or...
Operant chambers are small enclosures used to test animal behavior and cognition. While traditionally reliant on simple technologies for presenting stimuli (e.g., lights sounds) recording responses made basic manipulanda levers buttons), an increasing number of researchers beginning use Touchscreen-equipped Chambers (TOCs). These TOCs have obvious advantages, namely by allowing present a near infinite visual as well increased flexibility in the types that can be recorded. We trained...
Behavioral flexibility, adapting behavior to changing situations, is hypothesized be related new environments and geographic range expansions. However, flexibility rarely directly tested in a way that allows insight into how works. Research on great-tailed grackles, bird species has rapidly expanded their North America over the past 140 years, shows grackle manipulatable using colored tube reversal learning generalizable across contexts multi-access box). Here, we use these results conduct...

Behavioral flexibility (hereafter, flexibility) should theoretically be positively related to behavioral inhibition inhibition) because one need inhibit a previously learned behavior change their when the task changes (the component). However, several investigations show no or mixed support of this hypothesis, which challenges assumption that is involved in making flexible decisions.

Research into animal cognitive abilities is increasing quickly and often uses methods where behavioral performance on a task assumed to represent variation in the underlying trait. However, because these rely responses as proxy for ability, it important validate that structure does, fact, target trait of interest rather than non-target cognitive, personality, or motivational traits (construct validity). Although can be difficult, impossible, definitively assign one trait, way more likely...

Great-tailed Grackles ( Quiscalus mexicanus ) are a social, polygamous bird species whose populations have rapidly expanded their geographic range across North America over the past century. Before 1865, were only documented in Central America, Mexico, and southern Texas USA. Given rapid northern expansion of this species, it is relevant to study its role dynamics avian blood parasites. Here, 87 grackles Arizona (a population new center range) screened for haemosporidian parasites using...

Abstract The plains spotted skunk ( Spilogale interrupta ) is of conservation concern because widespread population declines and being considered for listing under the United States Endangered Species Act. Although taxon relatively rare difficult to study, recent research reports provided some information about skunks in Arkansas Missouri, USA. Using this information, we employed full simplified multivariate species distribution models evaluate cover type associations identify regions high...
Abstract Morphology is closely linked to locomotion and diet in animals. In animals that undertake long-distance migrations, limb morphology under selection maximize mobility minimize energy expenditure. Migratory behaviours also interact with diet, such migratory tend be dietary generalists, whereas sedentary taxa specialists. Despite a hypothesized link between migration status morphology, phylogenetic comparative studies have yielded conflicting findings. We tested for evolutionary...
