Distinctive casque morphologies among cassowary species

The irony of writing a story about 45-kilogram cassowaries—with forelimbs as small as those of chickens—for a blog called Wing Beat is not lost upon me. My coauthors and I are particularly excited to publish a paper for Ornithology about these flightless birds, as it seems most of the researched avian species in this journal are no larger than a mango.
