This partial wing skeleton from a female Ruby-throated hummingbird was created as part of a study of the hummingbird flight stroke (Hedrick et al., 2011). The bird in question weighed 3.43 grams, had a wing span of 10.7 cm and an exposed culmen length of 18.2 mm. The wing skeleton, extracted from a micro-CT scan of the bird, was posed to approximate the mid-downstroke configuration. Several bones in the scan are incomplete, notably the sternum and left scapula. Scans were performed at the Center for Nanoscale Systems at Harvard University, a member of the National Nanotechnology Infrastructure Network (NNIN). Funding for this work was provided by National Science Foundation grants IOS-0923606 and IOS-0744056 to Bret W. Tobalske, Douglas R. Warrick and Andrew A. Biewener.
