Geographical variation in the canary

AI Rating: 1/10 - This 1968 ornithological monograph by Austin Loomer Rand examines subspecies and morphological variations in canaries (genus Serinus) across geographic regions, based on museum specimens and measurements. Purely scientific taxonomy with no progressive political messaging, social justice themes, identity politics, or diversity/inclusion elements. Focuses entirely on biology and distribution, predating modern cultural debates.
