A lot of Bird Guides are done by artists (not photographs). Roger Torry Peterson/ Sibley. I like them, as there is a fair amount of "variation" in birds (age/season) so the guides with photos sometimes are too exact, and they can't highlight all variations. David Sibley's are what I keep in my bag. (He has a birding basics guide thats pretty good too) https://www.sibleyguides.com/ https://www.sibleyguides.com/ Roger Torry Peterson (RIP) https://en.wikipedia.org/wiki/Roger_Tory_Peterson https://en.wikipedia.org/wiki/Roger_Tory_Peterson has an institute named after him https://rtpi.org/about/ https://rtpi.org/about/
