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…

A fresh perspective on carp feeding behavior in an aquaculture pond and its consequences for individual growth

Abstract The common carp (Cyprinus carpio) is an important species in global aquaculture. To optimize its production, it is necessary to understand its behaviour in relation to environmental and management factors. This study investigated the spatial and temporal dynamics of carp behaviour in a semi-intensive aquaculture pond under controlled feeding…

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…

Open Protocols, the new standard for acoustic tracking: results from interoperability and performance tests in European waters

Abstract Background The lack of compatibility between acoustic telemetry equipment from different manufacturers has been a major obstacle to consolidating large collaborative tracking networks. Undisclosed encrypted signal coding protocols limit the use of acoustic telemetry to study animal movements over large spatial scales, reduce competition between manufacturers, and stifle innovation.…

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…
