Foraging Movement Patterns of Lactating Mexican Long-Nosed Bats in Central Mexico

Abstract The Mexican long-nosed bat (Leptonycteris nivalis) is a nectar-feeding bat distributed seasonally between Mexico and the United States, and it has been declared an endangered species in both countries. Here, we describe for the first time the movement patterns and locations of foraging areas used by lactating females from…

Insights from a decade of using the Motus network to track boreal bird species from Observatoire d’oiseaux de Tadoussac, Québec to temperate and tropical wintering grounds

Abstract Migration is the least-studied phase of the life cycle for many bird species, despite its importance to the full understanding of their life history traits and conservation. Between 2014 and 2023, we deployed tracking devices at Observatoire d’oiseaux de Tadoussac, Québec and used the Motus Wildlife Tracking System to…

Hemlock looper outbreak: new insight about how Black-backed Woodpecker (Picoides arcticus) respond to resource pulses in eastern Canada

Abstract Black-backed Woodpecker (Picoides arcticus) is known to benefit from pulse-resource disturbances in boreal forest for example, by colonizing recently burned habitats. Although insect outbreaks are ubiquitous in some parts of the eastern boreal forest, the opportunities offered by these natural disturbances for the Black-backed Woodpecker remain poorly understood. Between…

MEXICAN SPOTTED OWLS USE FOREST MOSAICS AFFECTED BY TIMBER HARVEST, INSECTS, AND WILDFIRE

Abstract Understanding how species of conservation concern interact with natural disturbances provides insights into their evolutionary environment and can inform land management and conservation planning. We examined the breeding season nocturnal space use (i.e., foraging ecology) of three Mexican spotted owls (Strix occidentalis lucida) in southern New Mexico, USA that…

Genetic relatedness shapes social dynamics in a threatened finch: implications for population assessment

Abstract Tropical granivorous finches often form large flocks around resources. The composition of these flocks, whether they are random groups of individuals or comprise related birds travelling together, is currently unknown. To bridge this knowledge gap, we combined high-frequency location tracking with comprehensive genetic sequencing to investigate the relationship between…

Migratory movements of bats are shaped by barrier effects, sex-biased timing and the adaptive use of winds

Abstract Background Migratory bats perform seasonal movements between their summer and winter areas. When crossing ecological barriers, like the open sea, they are exposed to an increased mortality risk due to energetically demanding long-distance flights and unexpected inclement weather events. How such barriers affect bat migratory movements is still poorly…

Beyond tracking: Advancing animal ecology through the longitudinal sampling of individuals

Abstract: Rarely, is there an opportunity to study and directly observe the same migratory animal across both breeding and nonbreeding seasons. In a rare, documented case, we highlight a live reencounter of a female Setophaga ruticilla (American Redstart) on its nest during the breeding season— an individual that was originally…

Conservation-focused mapping of avian migratory routes using a pan-European automated telemetry network

Abstract Accelerated biodiversity loss has destabilized functional links within and between ecosystems. Species that cross different ecosystems during migration between breeding and nonbreeding sites are particularly sensitive to global change because they are exposed to various, often ecosystem-specific, threats. Because these threats have lethal and nonlethal effects on populations, many…

Satellite tracking of American Woodcock reveals a gradient of migration strategies

Abstract Diversity in behavior is important for migratory birds in adapting to dynamic environmental and habitat conditions and responding to global change. Migratory behavior can be described by a variety of factors that comprise migration strategies. We characterized variation in migration strategies in American Woodcock (Scolopax minor), a migratory gamebird…
