Changes in Patterns of Territory and Habitat Overlap in Wood-Warblers Over Evolutionary Time
… habitats. I used the radiation of Dendroica wood-warblers to test these two alternative hypotheses and determine how closely related species partition space and habitat, and how patterns of spatial overlap and habitat use change over evolutionary timescales. I measured territory and habitat …

Spring Phenology and Trophic Ecology of Trees, Caterpillars, and Migrating Neotropical -Nearctic Songbirds
… ecology of forest trees, caterpillars, and wood warblers (Parulidae) and vireos (Vireonidae) during spring migration in 2001--2003 at Trelease Woods, a deciduous forest fragment near Urbana, Illinois, USA (40°09'N, 88°10'W). I hypothesized that (1) the photoperiod-driven pattern of …

Roots of Enquiry: Farmers, Forests and Tree Cover Change in Kwahu East, Ghana
… changes in Ghana out of concern for migratory wood warblers since 2011. Based on a small field site in the forest-farm landscape of Kwahu East, Ghana, their research concluded that tree cover is declining. They hypothesised that this could be affecting the birds’ wintering habitat and wanted to …

Migratory Stopover of Songbirds in the Western Lake Erie Basin
… Warbler (S. virens), and a guild of transient wood warblers (Parulidae) were analyzed using the Dail and Madsen (2011) generalized hierarchical N-mixture model. This is an open-population model that simultaneously estimates parameters that influence the abundance and detection probability of …

Post-fledging habitat use and movements of worm-eating warblers in the Tennessee River Gorge
Declines in Neotropical migratory birds have been observed over the past several decades. Species with particular habitat needs, termed ‘specialists’, are especially at risk given continual habitat loss. These downward trends have prompted researchers to investigate species’ life histories and …

Geographic variation of song within and between subspecies of the Mangrove Warbler (Setophaga petechia castaneiceps and S. p. rhizophorae)
… due to their song-learning behavior. Among Wood Warblers (Fam. Paruliade), The Yellow Warbler ( Setophaga petechia) is one of the most widespread and geographically diverse species. It is comprised by three groups of several subspecies which represent a great variety on morphological traits, …

Modelling mitigation of bird population declines in the UK through landscape-scale environmental management.
… and mixed land-use sites: heathland and woodland in the New Forest (Hampshire) and arable farmland with scattered woodlands in Cambridgeshire. Recently acquired, high resolution airborne remote sensing datasets (Light Detection and Ranging, LiDAR) were used to develop metrics that …
