Feather illustration for non-biologists! It occurred to me that some of you might find this useful. It starts with a necessary biology lesson, because I find that understanding the structure and function of feathers will greatly improve accurate rendering of those feathers.
A lot of this is general - obviously you can find all kinds of exceptions in the natural world (penguins, ratites, I’m looking at you guys). But it should cover the bulk of the illustration needs if you’re not comfortable drawing feathers and want some ideas on how to improve.
For photo references, I highly recommend birdpixel (a very generous online art reference created by Leena and Vivek Khanzode), Cornell’s Macaulay Library, and Piranga, which is mostly aimed at North American bird banders but shows excellent close-ups of a variety of species.
