Feathers Not Just For Flying is a lovely book. Which has absolutely nothing to do with any current gaming characters, or any Summer movies. Thankfully. Its just a lovely book about birds that is beautifully illustrated, easy to read and just, very interesting.
(The birds mentioned are all natives of North America, but that didn't bother me. The examples used weren't too exotic, and many of their counterparts are in my garden.)
Feathers can shade out sun like an umbrella,
or attract attention like fancy jewelry.
