Thank you for viewing! This is a field guide perfect for birdwatching, with detailed illustrations and explanations. There is some yellowing due to aging. I am selling this as it came up during a home clean-out ☺︎ Please understand that this is a used item stored at home, and only purchase if you are okay with that ♩ - Title: Viewing, Reading, Understanding: A Field Guide to Wild Birds - Author: Hiroaki Miyazaki
