...-doves ( Streptopelia risoria ) under four thermal regimes: resting, post-flight, heating via radiative lamps, and cooling via wind. We measured internal body temperature and skin-level temperature (under the plumage) using thermal PIT tags alongside surface temperature using a thermal imaging camera...

... are physiologically capable of controlling the sound-generating syringeal membranes in the ring dove ( Streptopelia risoria ) syrinx. We establish the role of the tracheolateralis muscle and propose a new function for the sternotrachealis muscle. The tracheolateralis and sternotrachealis muscles have an antagonistic...

... but much less so in non-songbirds, the songs of which are often regarded as relatively simple. We examined mechanisms of frequency and amplitude modulation of phonation in ring doves Streptopelia risoria ,which are non-songbirds. Spontaneous coo vocalizations were recorded together with concurrent pressure...

... ) and transitions between gaits in cockatiels ( Nymphicus hollandicus ) and ringed turtle-doves ( Streptopelia risoria )trained to fly in a recently built, variable-speed wind tunnel. Gait use was investigated via a combination of three-dimensional kinematics and quasi-steady aerodynamic modeling of bound...
