"A Check-List of the Birds of Idaho" by M. Dale Arvey is a scientific publication written in the mid-20th century. The book serves as an initial compendium for the avifauna of Idaho, providing an organized list of bird species observed in the state. The work highlights the lack of comprehensive literature on the topic and aims to encourage further research and documentation in ornithology. The content of the book consists of an extensive checklist of 292 bird species found in Idaho, categorized by their taxonomic status and geographic distribution across the state. Each entry includes references to occurrence, habitat, and the commonality of the species as reported by various ornithological studies and fieldwork conducted over a period of five years. The checklist serves both as a resource for amateur birdwatchers and professionals alike, and as a foundational text for future studies aimed at understanding and expanding knowledge about Idaho's bird populations.
