Birds of a Feather: Capturing Avian Shape Models from Images
Yufu Wang, Nikos Kolotouros, Kostas Daniilidis, Marc Badger
Computer Vision and Pattern Recognition (CVPR), 2021
We capture species-specific shape models from image collections and show that recovered shapes are consistent with the avian phylogeny.

Pigeons produce aerodynamic torques through changes in wing trajectory during low speed aerial turns
Ivo Ros, Marc Badger, Alyssa Pierson, Lori Bassman, Andrew Biewener
Journal of Experimental Biology, 2015
Unlike cats, pigeons produce aerodynamic moments to reorient in mid-air.
Pigeons steer like helicopters and generate down-and upstroke lift during low speed turns
Ivo Ros, Lori Bassman, Marc Badger, Alyssa Pierson, Andrew Biewener
Proceedings of the National Academy of Science (PNAS), 2011
I created a dynamics model of a pigeon’s wings and body, which we use to estimate aerodynamic forces from wing and body kinematics.
