Thoracic and Coracoid Arteries In Two Families of Birds, Columbidae and Hirundinidae

"Thoracic and Coracoid Arteries In Two Families of Birds, Columbidae and Hirundinidae" by Marion Anne Jenkinson is a scientific study from the early 1960s that examines the detailed anatomy of pigeons and swallows, specifically focusing on the thoracic and coracoid arteries. The publication sets out to discover the differences in these blood vessels within and between the Columbidae (pigeons) and Hirundinidae (swallows) families, and what these variations say about how the birds are classified. Through careful dissection of many bird specimens, Jenkinson explores the muscle and artery structures, noting similarities and differences and connects arterial variations to differences in body structure within and between pigeons and swallows, suggesting these differences relate to how the birds have physically adapted over time.
