Urbanization and migratory status shape nonbreeding space use behaviors in a North American songbird

Emily J. Williams, Alex E. Jahn, Hilary A. R. Mann, Nathan Alexander et autres

Understanding how and why animals use space is core to virtually all aspects of ecology, from influencing individual fitness, to predicting impacts of global change. Yet, most of what we know comes from studies focused on the breeding season, which represents just …

Effects of severe weather on shorebirds: Evidence of disrupted refueling and delayed departure on southbound migration

Shannon Fraser, Devin R. de Zwaan, Hilary A. R. Mann, Julie Paquet et autres

Abstract Severe weather events are more frequently impacting wildlife, especially in climate‐sensitive ecosystems like coastal habitats. A particularly vulnerable stage for migratory species is juvenile movement between natal and non‐breeding habitats. Globally, coastal habitats represent critical stopover or staging sites during postbreeding …

Determinants of multiple brooding in Barn Swallows (Hirundo rustica) in Atlantic Canada

Hilary A. R. Mann, Tara L. Imlay, Marty L. Leonard

Multiple brooding is an important component of reproductive success in many birds and the frequency of this behaviour has been linked to intrinsic (e.g., age, experience) and extrinsic factors (e.g., weather and food availability). When extrinsic factors drive multiple brooding, it may …

Annual adult survival rates for four sympatric breeding swallow species: effects of environmental factors and density-dependence

Tara L. Imlay, Hilary A. R. Mann, Andrew C. Ding, Peter Thomas et autres

Swallow (Family: Hirundinidae) populations in the Canadian Maritimes have declined since the 1980s. Using mark–recapture data from 2012 to 2019, we determined apparent annual adult survival rates for Barn ( Hirundo rustica Linnaeus, 1758), Tree ( Tachycineta bicolor (Vieillot, 1808)), Bank ( …

Multiple brooding in Barn Swallows (Hirundo rustica): Extrinsic determinants and implications on population growth

Hilary A. R. Mann

In many species of birds, the number of broods produced in a breeding season is an extremely important component of reproductive success. However, for many multi-brooded species, we have a poor understanding of both the specific factors that affect the incidence of …

Effects of Extreme Tidal Events on Semipalmated Sandpiper ( Calidris pusilla ) Migratory Stopover in the Bay of Fundy, Canada

Hilary A. R. Mann, Diana J. Hamilton, Julie Paquet, Cheri L. Gratto‐Trevor et autres

The objective of this study was to determine the implications of extreme tidal events on duration of stay and behavior of Semipalmated Sandpipers (Calidris pusilla) during migratory stopover in Cobequid Bay, Nova Scotia. This area is part of the Bay of Fundy …
