520 ## - SUMMARY, ETC.
Summary, etc. "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.
