Age and Sex Influence Natal and Breeding Dispersal of Purple Martins

Autor: Geoffrey L. Holroyd, Carolyn A. Cook, Glen T. Hvenegaard, Hardy Pletz, Myrna Pearman

Publikováno v: Western Birds. 52:296-310

Dispersal patterns deepen our understanding of population dynamics. Dispersal by all age and sex classes enhances a species’ ability to respond to environmental changes, such as in habitat availability, artificial nest sites, and climate. The migra

Migratory stopover timing is predicted by breeding latitude, not habitat quality, in a long-distance migratory songbird

The timing of migration can have important survival impacts, as birds must synchronize their movements with favourable environmental conditions to reach their destination. The timing of arrival at and duration of migratory stopover may be largely gov

Determining fine-scale migratory connectivity and habitat selection for a migratory songbird by using new GPS technology

Autor: Amanda Shave, Anne Savage, Kelly Applegate, Myrna Pearman, Kelsey Bell, Kevin C. Fraser, James D. Ray, Joseph Siegrist, Alisha Ritchie

Publikováno v: Journal of Avian Biology. 48:339-345

Migratory aerial insectivores are among the fastest declining avian groups, but our understanding of these trends has been limited by poor knowledge of migratory connectivity and the identification of critical habitat across the vast distances they t

Ecological Causes and Consequences of Intratropical Migration in Temperate-Breeding Migratory Birds

Autor: Glen T. Hvenegaard, Paul Mammenga, Bridget J. M. Stutchbury, James D. Ray, Tim Shaheen, Anne Savage, Raafia Siddiqui, Myrna Pearman, Kevin C. Fraser, Nanette Mickle, Kelly Applegate

Publikováno v: The American Naturalist. 188:S28-S40

New discoveries from direct tracking of temperate-breeding passerines show that intratropical migration (ITM) occurs in a growing number of species, which has important implications for understanding their evolution of migration, population dynamics,

Tracking mated pairs in a long-distance migratory songbird: migration schedules are not synchronized within pairs

Autor: Cassandra Silverio, James Mejeur, Kevin C. Fraser, Nanette Mickle, Bob Aeppli, Patrick M. Kramer, Myrna Pearman, Bridget J. M. Stutchbury, Anne Savage

Publikováno v: Animal Behaviour. 114:63-68

In long-distance migrants, it has been hypothesized that re-pairing in spring is facilitated if, on the wintering grounds, formerly mated individuals maintain close proximity or occupy ecologically similar habitat, which then results in more synchron

The influence of morphological variation on migration performance in a trans-hemispheric migratory songbird

Autor: Emily A. McKinnon, Paul Mammenga, Mackenzie Pearson, Myrna Pearman, James Mejeur, Glen T. Hvenegaard, James D. Ray, John Tautin, Lauren Moscar, Kevin C. Fraser, Lawrence Lam, Kelly Applegate

Publikováno v: Animal Migration, Vol 2, Iss 1, Pp 86-95 (2015)

For long-distance migratory songbirds, morphological traits such as longer wings and a smaller body size are predicted to increase migration efficiency. Due to previous limitations in our ability to track the long-distance journeys of small-bodied bi
