After reading the text, what, if any, benefits are there for an owl to have darker feathers on the volcanic islands?

It’s possible that sulfur-driven colors provide benefits to the owls, Romano says. Volcanic islands are often thick with vegetation supported by dark, fertile soil. Darker feathers might help the predatory owls disappear into their forest surroundings. The owls might also avoid the toxic effect of high sulfur exposure by shuttling a glut of sulfur into making more pheomelanin. Melanin has been previously tied to detoxifying pollutants in sea snakes, for instance (SN: 8/14/17).
