William Dreuth's Study of Bird Migration
in Lincoln Park, Chicago

A 16 Year Study of Bird Migration in Lincoln Park, Chicago

About the Content

The data in the tables is organized into 7 columns (as they appear in the booklet) - Species, Earliest Date of Arrival, Average Date of Arrival, Average Date Last Seen, Latest Date Seen, Number of Days Seen, and Number of Years Seen. Pay particular attention to the last 2 columns as they give a good idea of status in Dreuth's study. I've included Dreuth's status information on subspecies - Dreuth was a careful, meticulous observer and he kept detailed notes about his bird sightings, including subspecies, so I only thought it right to preserve this information. The content has been divided into 5 sections; use the navigation tabs to move between the sections.

Note: On smaller devices such as a cell phone, the tabular data may not display in its entirety and will require horizontal scrolling to view.

Legend
  • Birds that were full species in Dreuth's time, but are no longer so, have quotation marks around their common and scientific names, e.g., "Blue Goose", "Chen caerulescens"
  • Subspecies have quotation marks around the first modyfying part of their common names, e.g., "Gambel's" White-crowned Sparrow
  • Dates in parenthesis represent other dates, e.g., (Aug 21, 1936)
