Authors used playback recordings of Ferruginous Pygmy Owl's (Glaucidium brasilianum) to elicit mobbing behavior & looked for factors that could explain which species of #birds were #mobbing
Reminded me of @RosemaryMosco 's Northern Pygmy Owl cartoon😂 (same genus of bird)
Spoilers from the Santana de Lima et al. (2018) paper (linked above)

Body mass & trophic guild (along with phylogenetic clade) were the best predictors of #mobbing behaviors in #birds in dry forests in Brazil

🏙️#Sex biases in the individuals studied in the lab & field. Why is it more often males of a species? What data are we missing because of that bias? 🤔

Any recommendations for ways to collect data about color & pattern from images of #wildlife? We want to quantify things like %cover by a color & intensity.
Have enjoyed reading some of the work by Davis & Grayson on quantifying #color, hue, % coverage in #newts and other animals.
They used Fovea Pro, a Photoshop add in. The newer version (QIA-64) costs ~$800 😬
Am also considering the methods of Paterson & Blouin-Demers where they quantify continuous variation in throat color in #lizards using Adobe & ultimately analysis in #imageJ (but haven't had time to test it out yet)
