Inadequate thermal refuge constrains landscape habitability for a grassland bird species [PDF]

open access: yesPeerJ, 2017
Ecologists have long recognized the influence that environmental conditions have on abundance and range extent of animal species. We used the northern bobwhite (Colinus virginianus; hereafter bobwhite) as a model species for studying how microclimates ...

Water bathing alters the speed-accuracy trade-off of escape flights in European starlings [PDF]

open access: yes, 2009
Birds of most species regularly bathe in water, but the function of this behaviour is unknown. We tested the hypothesis that water bathing is important in feather maintenance, and hence should enhance flight performance. We manipulated European starlings'

Using step width to compare locomotor biomechanics between extinct, non-avian theropod dinosaurs and modern obligate bipeds [PDF]

open access: yes, 2017
How extinct, non-avian theropod dinosaurs locomoted is a subject of considerable interest, as is the manner in which it evolved on the line leading to birds. Fossil footprints provide the most direct evidence for answering these questions. In this study,

Northern bobwhite chick survival, growth, and movement in relation to broadcast supplemental feed and drought

open access: yesWildlife Biology, Volume 2026, Issue 1, January 2026.
The northern bobwhite is an economically important species across its geographic range that has experienced declining population numbers. There is ample research dedicated to evaluating management practices for the adult life stage. However, effects of management on bobwhite chicks remain understudied, despite this being the most vulnerable age class ...

Testing radiotransmitter attachment techniques on northern bobwhite and chukar chicks

open access: yesWildlife Society Bulletin, 2011
We compared 4 external radiotransmitter attachment techniques to determine the optimum attachment method on chicks of 2 galliform species. The attachment methods included tissue glue, silicone gel, suturing, and leg harness.
