This plate, by Prideaux John Selby, features detailed illustrations of two tern species: the Gull-Billed Tern (Gelochelidon nilotica) and the Sandwich Tern (Thalasseus sandvicensis). Selby has carefully rendered each bird with attention to anatomical detail and distinctive plumage. The top bird is labeled as the Gull-Billed Tern, shown in its full body profile standing on a rocky surface. Beside it, there is a detailed view of the Gull-Billed Tern’s head in summer plumage, highlighting its characteristic black cap. Below, the Sandwich Tern is depicted with its longer, slender body and more pointed beak. Both birds are placed against a minimalist background, allowing viewers to focus on their unique physical traits.
Gull-Billed Tern (Gelochelidon nilotica): Known for its robust, short bill and relatively large body, the Gull-Billed Tern is a versatile species found in coastal areas and inland wetlands across Europe, Asia, and parts of North America. Unlike most terns, it often forages over open land, hunting small insects and other prey.
Sandwich Tern (Thalasseus sandvicensis): This slender tern is easily identifiable by its longer black bill with a yellow tip. Typically found along coasts and islands, the Sandwich Tern migrates seasonally, moving to warmer regions during winter months. Its diet consists mainly of fish, which it catches through diving.
Selby’s Illustrations of British Ornithology
Prideaux John Selby’s Illustrations of British Ornithology, published between 1821 and 1834, is one of the most significant works in 19th-century ornithological literature. Selby, an English naturalist and artist, produced a two-volume set that featured life-sized depictions of British birds, a departure from earlier works that used smaller formats. His background as both a scientist and an artist allowed him to render birds with remarkable accuracy and beauty.
