Journal of the Arkansas Academy of Science

Waterbird use of two moderately-sized reservoirs in northwest Arkansas was studied in the autumns of 1993 and 1995. In addition to waterbird counts; surface area, water temperature, conductivity, pH, turbidity, dissolved oxygen, macrophyte presences, number of total macroin vertebrates and degree of human activity were evaluated. Lake Fayetteville supported a greater overall waterbird species richness and species abundance than Lake Wedington. The observed number of ducks per hectare showed a significant difference between the lakes in both 1993 and 1995. Surface feeding birds were significantly more abundant at Lake Fayetteville in both 1993 and 1995, whereas diving birds, which feed …
