Cell diameters of the trabecular foam in the beak of Wreathed Hornbill, for example, are ~3x that of the Toco Toucan's beak, so I wonder if the radiative properties of Wreathed Hornbill beaks are closer to those of the Southern Yellow-billed Hornbills, featured in the studied. Noteworthy is that the Wreathed Hornbills live in a tropical environment where the need for non-evaporative cooling tactics could be similar to that in the Neotropics where Toco Toucans dwell.
Also, "A fine-gauge NiCr-NiAl thermocouple ... was inserted approximately 10 mm into the cloaca ..." So the authors skip the "foreplay" of considering structural features of the beak foam, and go straight for penetration, 10 mm into the cloaca with a thermocouple!!
I stumbled late on the "news" after a colleague sent this: https://youtu.be/BKorP55Aqvg Also, no one specified that those lines have to be confined to 3D, right? ;)
