Polymorphism: my latest Birdword comic for Cornell Lab. www.allaboutbirds.org/news/birdwor...

A three panel comic. In panel 1, there's a torn piece of paper with a definition: Polymorphism: noun. When one species contains two or more types of individuals (morphs) that differ by color or other physical characteristics unrelated to sex, age, locality, or season. In panel 2, there are red-tailed hawk morphs (calurus subspecies): light, dark, and intermediate. Note: these fall on a spectrum. In panel 3, there are red-tailed hawk morphs that I wish existed: blue-footed, red-winged, pileated (with a woodpecker head), bioluminescent, pocket-sized, vulturine (with a bare head) and resplendent (with green quetzal feathers and a very long tail).

I haven't seen any starter packs made for behavioral ecology yet, so I decided to create one! If you are a behavioral ecologist (any career stage), please reply so I can add you to the list so we can more easily find each other. go.bsky.app/9mAuB6x
