Hong G, Tobalske B, van Staaveren N, Leishman E, Widowski T, Powers D, et al.
R Soc Open Sci . 2025 Feb; 12(2):241191. PMID: 40012755
Domestic chickens kept for egg laying navigate inclines such as ramps in some commercial housing systems to aid in transitions between housing tiers. Laying hens use their wings and hindlimbs...

Crandell K, Powers D, Tobalske B
J Exp Biol . 2025 Feb; 228(4). PMID: 39976466
Avian plumage contributes to the regulation of body temperature. In most climates, avian heat dissipation occurs passively via radiation, conduction and convection owing to the thermal gradient between the environment...

Anwar M, Tobalske B, Agrawal S, Mongeau J, Luo H, Cheng B
Proc Biol Sci . 2024 Nov; 291(2035):20241268. PMID: 39561797
Hummingbirds routinely execute a variety of stunning aerobatic feats, which continue to challenge current notions of aerial agility and controlled stability in biological systems. Indeed, the control of these amazing...

Haque M, Tobalske B, Cheng B, Luo H
J R Soc Interface . 2024 Oct; 21(219):20240391. PMID: 39471868
When a hovering hummingbird performs a rapid escape manoeuvre in response to a perceived threat from the front side, its body may go through simultaneous pitch, yaw and roll rotations....

Tu R, Delplanche R, Tobalske B, Inman D, Sodano H
Bioinspir Biomim . 2024 Oct; 19(6). PMID: 39413836
Bird flight is often characterized by outstanding aerodynamic efficiency, agility and adaptivity in dynamic conditions. Feathers play an integral role in facilitating these aspects of performance, and the benefits feathers...

Dial T, Collins L, Liao J, Tobalske B
J Exp Biol . 2024 Jul; 227(15). PMID: 39022908
Complex hydrodynamics abound in natural streams, yet the selective pressures these impose upon different size classes of fish are not well understood. Attached vortices are produced by relatively large objects...

Deetjen M, Chin D, Heers A, Tobalske B, Lentink D
Elife . 2024 Feb; 12. PMID: 38408118
Avian takeoff requires peak pectoralis muscle power to generate sufficient aerodynamic force during the downstroke. Subsequently, the much smaller supracoracoideus recovers the wing during the upstroke. How the pectoralis work...

Hong G, Tobalske B, van Staaveren N, Leishman E, Widowski T, Powers D, et al.
Poult Sci . 2024 Jan; 103(3):103375. PMID: 38198915
Domestic laying hens rely primarily on their hindlimbs for terrestrial locomotion. Although they perform flapping flight, they appear to use maximal power during descent and thus may lack control for...

Hong G, Tobalske B, van Staaveren N, Leishman E, Widowski T, Powers D, et al.
R Soc Open Sci . 2023 Nov; 10(11):230817. PMID: 38034124
In flying birds, the pectoralis (PECT) and supracoracoideus (SUPRA) generate most of the power required for flight, while the wing feathers create the aerodynamic forces. However, in domestic laying hens,...
