Space-Based Ornithology - Studying Bird Migration and Environmental Change in North America [PDF]

Natural fluctuations in the availability of critical stopover sites coupled with anthropogenic destruction of wetlands, land-use change, and anticipated losses due to climate change present migratory birds with a formidable challenge.

Radar And Visual Observations Of Autumnal (Southward) Shorebird Migration On Guam [PDF]

, 1988
Several species of shorebirds migrate between eastern Asia and the southern Pacific islands, Australia, and New Zealand. Observations made from Guam (13°25′N, 144°45′E) during autumn 1983 indicate that a significant number of birds take a direct route ...

Shape‐shifting in relative wing length of juvenile shorebirds: no evidence of developmental temperatures driving morphological changes

Ecography, EarlyView.
Morphological changes concurrent with climate change are increasingly identified in birds, often through decreasing body size and increasing appendage size. Such changes could have thermoregulatory implications, through the improved surface area to body ratio they provide.

Seasonal variation in community structure and elevational distributions of mammals and birds in the Central Himalayas

Ecography, EarlyView.
Montane species utilize various habitats along elevations to adapt to seasonality, providing an ideal opportunity to study how species respond to shifting environments. This study characterizes seasonal changes in community structure and elevational distributions across multiple taxa in the Central Himalayas.
