A Quantitative Study of the Nocturnal Migration of Birds
"A Quantitative Study of the Nocturnal Migration of Birds" by George H. Lowery Jr. is a scientific publication written in the mid-20th century. This work investigates the nocturnal migration patterns of birds through quantitative analysis, addressing previously unexamined aspects of avian behavior during migration. The study proposes to gather substantial data that will lend clarity to various hypotheses surrounding bird migration, focusing primarily on aspects such as flight densities, direction, and the influences of environmental factors. The opening of the study introduces the intriguing phenomenon of bird migration at night, highlighting the lack of comprehensive understanding in the field. Lowery outlines the various circumstantial observations that indicate migratory activity, such as sightings of birds on stormy nights and incidents of collisions with tall structures. He articulates the need for a structured, quantitative approach to accurately measure flight densities and their variations. Through telescopic observations focused on the moon, data collection was conducted over several nights, providing a rich dataset that aims to elucidate the nature of nocturnal migration and the variables influencing it. The introductory sections set the stage for an ambitious analysis intended to fill gaps in existing ornithological knowledge regarding nighttime bird movements.
Additions to the List of the Birds of Louisiana
"Additions to the List of the Birds of Louisiana" by George H. Lowery, Jr. is a scientific publication likely written in the late 1940s. This book serves as an important contribution to ornithology, specifically focusing on the avifauna of Louisiana. It systematically lists newly documented bird species and subspecies that have been observed in Louisiana since the publication of a previous notable work on the subject in 1938. The content of the book is a detailed catalog of bird species observed in Louisiana, offering extensive documentation that includes specific sightings, locations, and the status of various species. Lowery emphasizes the significance of these newly recorded birds, many of which were previously unrecognized in the region. The manuscript also discusses the evolving understanding of certain species' distributions, clarifying misunderstandings from prior literature. Additionally, the work is enriched by the contributions of fellow ornithologists and includes extensive field observations that enhance Texas's ornithological knowledge. Overall, this publication is an essential resource for researchers and bird enthusiasts interested in the birdlife of Louisiana and its changes over time.
