Many fundamental aspects of migration remain a mystery, largely due to our inability follow small animals over vast spatial areas. For more than 50 years, it has been hypothesized that, during autumn migration, blackpoll warblers ( Setophaga striata ) depart northeastern North America and undertake non-stop flight the Atlantic Ocean either Greater Antilles or coast South America. Using miniaturized light-level geolocators, we provide first irrefutable evidence that warbler, 12 g boreal...
Many species of birds and bats undertake seasonal migrations between breeding over-wintering sites. En-route, migrants alternate periods flight with time spent at stopover – the space where individuals rest refuel for subsequent flights. We assessed spatial scale movements made by during using an array automated telemetry receivers multiple antennae to track daily location over a geographic area ∼20×40 km. tracked 322 seven migratory vertebrate (5 passerines, 1 owl bat) spring fall on...
1. Some bat species make long-distance latitudinal migrations between summer and winter grounds, but because of their elusive nature, few aspects biology are well understood. The need for migratory stopover sites to rest refuel, such as used by birds, has been repeatedly suggested, not previously tested empirically in bats. 2. We studied migrating silver-haired bats (Lasionycteris noctivagans) at Long Point, ON, Canada. digital radio-transmitters track 30 using an array five towers that...
Long-distance migratory organisms are under strong selection to migrate quickly. Stopovers demand more time than flying and used by individuals refuel during migration, but the effect of fuel loads (fat) acquired at stopover sites on subsequent pace migration has not been quantified. We studied behaviour Grey-cheeked Thrush (Catharus minimus) a site in northern Colombia then tracked their using an intercontinental radio-telemetry array. Tracking confirmed long-distance flights 3000 km,...
Given that winds encountered on migration could theoretically double or half the energy expenditure of aerial migrants, there should be strong selection behaviour in relation to wind conditions aloft. However, evidence suggests juvenile songbirds are less choosy about at departure relative adults, potentially increasing during flight. To date, has yet a direct comparison flight efficiency between free-living adult and aloft, likely because challenges following known aged individual We used...
The degree to which spatial patterns influence the dynamics and distribution of populations is a central question in ecology. This even more pressing context rapid habitat loss fragmentation, threaten global biodiversity. However, relative landscape patterning remaining habitat, remains unclear. If pattern affects population size, managers may be able design landscapes that mitigate loss. We present results mensurative experiment designed test four vs. fragmentation hypotheses. Unlike...
We demonstrate that, after correcting for the effects of size, wing lengths, widths and thoracic weights forest damselfly Calopteryx maculata differ between populations along forested streams, those streams through pasture. Pasture landscapes can be considered as fragmented landscapes; are continuous. In some C. fly across intervening pasture to reach foraging sites in forest. propose that there is morphological plasticity within species revealed landscape process habitat fragmentation...
Knowledge of stopovers made by migratory birds comes mostly from studies at relatively fine spatial scales. While this focus yields important information about processes those scales, it ignores possible acting broader We established an array three automated radio-telemetry receiver towers housing ten antennas arranged to sample a landscape and its associated airspace Lake Erie in southern Canada. used digitally coded tags monitor the behavior multiple Swainson's Hermit Thrushes (Catharus...
During annual migrations between breeding and nonbreeding grounds, billions of land birds encounter migratory barriers en route . Although are thought to be more selective (i.e., cross under favorable wind conditions) spend time refueling at stopover sites when confronted with these barriers, there is no direct evidence support hypotheses. Using 2 automated radio-telemetry arrays situated before (south of) after (north a large ecological barrier (Lake Erie), we tracked departure decisions...
Island breeding birds present an ideal system for studying migratory movements in passerines because their populations are clearly demarcated, and individuals must depart on migration from a single location. The Ipswich Sparrow (Paserculus sandwichensis princeps) is subspecies of the Savannah that breeds exclusively Sable Island, Nova Scotia, Canada winters along Atlantic coast North America. We used network 34 automated VHF telemetry receivers to track radio-tagged adult juvenile Sparrows...

Using a broad-scale automated telemetry array, we explored post-fledging movements of blackpoll warblers breeding in Atlantic Canada. We sought to determine the full spatial scale dispersal, assess support for three hypotheses regional-scale movement, and whether learning influenced movement during this period. demonstrated that both young adults moved over distances more than 200 km prior initiating migration. Adults southwest, crossing Gulf Maine (GOM), consistent with commencement...
Accumulating evidence suggests that Atlantic populations of Leach's Storm-Petrels (Oceanodroma leucorhoa) are experiencing significant declines. To better understand possible causes these declines, we used geolocators to document movements small (∼50-g) pelagic seabirds during migration and the non-breeding period. During 2012 2013, movement tracks were obtained from two birds traveled in a clock-wise direction breeding colonies eastern Canada (Bon Portage Island, Nova Scotia, Gull...
Abstract Background Weather can have both delayed and immediate impacts on animal populations, species evolved behavioral adaptions to respond weather conditions. has long been hypothesized affect the timing intensity of avian migration, radar studies demonstrated strong correlations between broad-scale migration patterns. How affects individual decisions about initiation migratory flights, particularly at beginning remains uncertain. Methods Here, we combine automated radio telemetry data...
Considerable scientific effort has gone into examining how the spatial structure of habitat influences organism distribution and abundance in both theoretical applied contexts. An emerging conclusion from these works is that overall amount landscape matters most for species persistence more local attributes such as size arrangement patches secondary importance. In this study, we quantify when effects configuration (patch isolation) influence density three insects (Order: Diptera; Wyeomyia...
Knowledge of foraging movements during the breeding season is key to understanding energetic stresses faced by seabirds. Using archival light loggers (geolocators), a Bayesian state–space model, and stable isotope analysis, we compared Leach's storm‐petrels Oceanodroma leucorhoa their incubation periods in 2012 2013. Data were collected from two colonies, Bon Portage Island Country Island, which are 380 km apart along coast Nova Scotia, Canada. Based on allometry for procellariiform mass,...
Bird migration entails replenishing fuel stores at stopover sites. There, individuals make daily decisions whether to resume migration, and must also decide their time of departure. Variation in departure timing affects the total required complete a migratory journey, which turn fitness through arrival breeding wintering grounds. It is well established that are based on cues from innate rhythms, intrinsic factors extrinsic factors. Yet, virtually nothing known about physiological...
Abstract Most migratory songbirds travel between their breeding areas and wintering grounds through a series of nocturnal flights. The timing departures defines the potential flight duration thus distance covered during night. Yet, show substantial variation in departure timing. With this study, we aim to assess whether respective challenges migration route, namely its nature, help explain variation. At stopover site, caught Northern Wheatears ( Oenanthe oenanthe ) two subspecies that differ...
Knowledge of how landscape structure influences patterns animal space use is critical to developing sustainable management practices. For breeding songbirds that defend a territory embedded within larger home range, effects structural change on movement may be manifested at multiple spatial scales. We used radio-telemetry assess within-territory and range as functions the proportion clearcut-harvested versus naturally unforested land for two species Neotropical migrant songbirds. tested...
