I just finished these spot illustrations for a display that will go up at the Lindsay Wildlife Museum in Walnut Creek, Calif. The display describes raptors (owls, hawks, falcons and other birds of prey), and the spots illustrate lightweight bird bones, plus something I didn't know before: How raptors hold said prey.
It turns out that as certain leg muscles pull the raptors' sharp talons closed, the tendon attached to the underside of the claw catches on the folds of a sheath around the tendon as it fold together like an accordion. The underside of that specialized talon has a jagged set of teeth that catch on the folds and holds the talon in place so that the birds don't have to contract their muscles constantly.
I'll post the display when it's available.
It was another opportunity to work with Lisa Park-Steskal, who designed the new Old Sacramento signs for which I illustrated. (Also here and here.)
Lisa wanted a blueprint look but in a sketchy, loose style, as if the museum was jotting down relatable concepts to help visitors understand what was going on in a raptor's claws and bones.
