Factors Affecting Habitat Quality for Wintering Wood Thrushes in a Coffee Growing Region in Honduras

Connectivity of wood thrush breeding, wintering, and migration sites based on range-wide tracking.

Many migratory animals are experiencing rapid population declines, but migration data with the geographic scope and resolution to quantify the complex network of movements between breeding and nonbreeding regions are often lacking. Determining the most frequently used migration routes and nonbreeding regions for a species is critical for understanding population dynamics and making effective co...

Tracking long-distance songbird migration by using geolocators.

We mapped migration routes of migratory songbirds to the Neotropics by using light-level geolocators mounted on breeding purple martins (Progne subis) and wood thrushes (Hylocichla mustelina). Wood thrushes from the same breeding population occupied winter territories within a narrow east-west band in Central America, suggesting high connectivity of breeding and wintering populations. Pace of s...

Assessing habitat quality for a migratory songbird wintering in natural and agricultural habitats.

As tropical forests are cleared, a greater proportion of migratory songbirds are forced to winter in agricultural and disturbed habitats, which, if poorer in quality than natural forests, could contribute to population declines. We compared demographic indicators of habitat quality for a focal species, the American Redstart (Setophaga ruticilla), wintering in Jamaican citrus orchards and shade ...

تأثیر عوامل محیطی بر پراکنش زیستگاه‌های مطلوب جمعیت‌های زمستان گذران هوبره آسیایی در فلات مرکزی ایران

Predicting species’ distribution is a prerequsit for assessing threats, determining conservation status, and planning conservation programs. Asian houbara Chlamydotis macqueenii is one of the most valuable game species threatened by extinction. We estimated the distribution of potential suitable habitats of wintering populations of Asian houbara bustard in central Iranian plateau using maximum ...
