Ravens and crows are noted for liking to pick up shiny things to line their nests. I'm not sure if it's the case with ravens in particular, but many species of birds have males that attract females of their species by making them more attractive nests, so picking up colorful or shiny things makes their nest prettier, and stocking up on the bling makes it more likely they'll get a mate.
It can be a problem, because they pick up things like car keys or coins, and fly away with them.
The bust on the bottom right panel is very...distracting.
