"Essays on early ornithology and kindred subjects" by James Roxburgh McClymont is a scientific publication written in the early 20th century. This book delves into topics related to bird species, their historical sightings, and ornithological lore from earlier explorers and travelers, reflecting significant interests and studies from the age of discovery. The book is structured as a collection of essays that explore various facets of early ornithological knowledge. Among the subjects discussed are the mythical "rukh" of Marco Polo’s narratives, the penguins and seals encountered during Vasco da Gama's voyages, and the etymology of terms like "emu." McClymont provides historical context by examining the discoveries made by explorers in Australia, New Zealand, and the Banda Islands, while also considering the linguistic origins of bird names. Each essay not only presents factual ornithological data but also intertwines the wonder and often fanciful tales surrounding the observations of these birds, offering readers insights into how early scientists and navigators perceived avifauna in unfamiliar territories.
