Studies of the Bird Life of Denton County, Texas

"As a means of defining the purpose of the problem, the following objectives were considered: (1) to list the species of birds observed in Denton and neighboring counties; (2) to assign a descriptive status to each species; (3) to estimate the relative abundance of each species (4) to annotate the list with data from other sources, when additional data provide a more accurate and complete description of the status of the species in Denton County; (5) to designate the section of the county in which each species was most frequently observed; and (6) to briefly summarize the changes in bird populations during the period 1950-1956, and to suggest some hypotheses which help explain these changes." -- leaf 6
