Squeezing through strategies for navigating tight spaces in flight
Meeting Abstract 20.3 Friday, Jan. 4 Squeezing through: strategies for navigating tight spaces in flight WILLIAMS, C.D.*; BIEWENER, A.A.; Harvard Univ., Boston; Harvard Univ., Boston charleswilliams@fas.harvard.edu Navigating through confined spaces is one of the more impressive tasks flying animals can accomplish. We presented pigeons (C. livia) trained to navigate through a field of vertical obstacles with an […]

Metabolic Power, Mechanical Efficiency, and Heat Production during Hovering and Forward Flight in Calliope Hummingbirds (Selasphorus calliope)
Meeting Abstract 20.1 Friday, Jan. 4 Metabolic Power, Mechanical Efficiency, and Heat Production during Hovering and Forward Flight in Calliope Hummingbirds (Selasphorus calliope) POWERS, D.R.*; TOBALSKE, B.W.; George Fox University, Newberg, OR; University of Montana, Missoula, MT dpowers@georgefox.edu Flight requires higher power output than other forms of animal locomotion, and the effects flight speed upon power have […]
High speed pursuit in barn and cliff swallows
Meeting Abstract 20.4 Friday, Jan. 4 High speed pursuit in barn and cliff swallows SHELTON, RM*; JACKSON, BE; HEDRICK, TL; Univ. of North Carolina, Chapel Hill; Univ. of North Carolina, Chapel Hill; Univ. of North Carolina, Chapel Hill rmshelto@email.unc.edu Birds require visually guided interception techniques to catch prey in flight, to track down potential mates, and to […]
Direct aerodynamic force measurements in avian flight support active upstroke hypothesis
Meeting Abstract 20.5 Friday, Jan. 4 Direct aerodynamic force measurements in avian flight support active upstroke hypothesis LENTINK, D; Stanford University; Wageningen University; Harvard University dlentink@stanford.edu Birds dynamically change the shape of their wing during the stroke, resulting in dramatic differences in wing shape between the up- and down-stroke. The wing is partially folded during the upstroke, […]
Testing the melanism-desiccation hypothesis using experimental evolution
Meeting Abstract 19.1 Friday, Jan. 4 Testing the melanism-desiccation hypothesis using experimental evolution GIBBS, AG*; RAJPUROHIT, S; PETERSON, LM; ORR, A; Univ. of Nevada; Univ. of Pennsylvania; Univ. of Nevada; Univ. of Nevada allen.gibbs@unlv.edu Several Sophophora species on the Indian subcontinent show clinal patterns in pigmentation, with darker populations occurring in northern, drier locations. We used experimental […]
