Wing images used for testing new methods for estimating the total wing area of birds

Images of extended wing preparations of 112 specimens representing 40 avian families were used for testing new methods for estimating the total wing area of birds., Spread wings photographed at the ROM were placed on white paper on a copy stand with a Nikon Z50 mirrorless camera mounted directly above the wing. An L-shaped ruler was placed next to the wing to provide the scale. Two Godox LEDP260C Bi-Color LED light panels on tripods were set at 100% brightness and 5000K color temperature and placed on either side of the camera to minimize shadows. Large wings were photographed in the ROM’s photo studio. Wings at LSU were photographed using a hand-held camera and a digital or manual leveler to ensure the camera was directly above the wing. To reduce measurer error, photographs were taken and digitally measured only by H.F. and M.S. Processed images were obtained using ImageJ v.1.53 (U.S. National Institutes of Health, Bethesda, Maryland). We set the scale using the scale ruler in the image and used the “Threshold” tool to transform the photo into a binary (black and white) image, sometimes followed by the “Fill Holes” option. Most images were furthe..., Standard image visualization software that can open JPG files., ## Images of spread wing specimens used for the evaluation of new methods for estimating the total wing area of birds
