From Beguiled by the Wild: The Art of Charley Harper, page 105 (Flower Valley Press, 1994):
Good cheer is a cardinal virtue. And what is more cheerful than waking up on a snowy morning to find your backyard full of cardinals? With all that red and white, who could be blue? Ever wonder why birds of a feather flock together? Maybe because it's easier than flocking apart. Or because that's where the vittles are. Is your bird feeder down to the last sunflower seed? Fill it fast - an empty bird feeder is a cardinal sin.
This also appeared in Charles Harper's Birds & Words, page 146 (AMMO Books, 2008, reissued from 1972 original).

ABOUT EMAILING FOR PRICE:
1. Once an item is "sold out" and only available thru "secondary" or "resale" sources, pricing can vary day by day or hour by hour as resales occur. In such instances, the prices you see on our website may represent the last of those items sold as opposed to today's price. That is why we often tell you to "email" for pricing. And that is why prices often change without notice.
2. We apologize that there are some artists who do not allow on-line listings of their prices.
In either event, when you email for pricing, you must include your phone number and location. We'll get back to you quickly.
