Utilization Of Hydrilla By Ducks And Coots In Central Florida

Foods consumed by 115 ducks and coots (Fulica americana) collected from 2 central Florida study sites were analyzed to assess the importance of the exotic pest species hydrilla (Hydril/a verticil/ata) as a food plant. Contents of esophagi or gizzards were identified and measured by volumetric displacement. Hydrilla was the most important identifiable food on both study sites in terms of mean of volumetric percentages (aggregate percentage) and frequency of occurrence. Implications of findings with respect to waterfowl habitat and aquatic weed control are discussed.

Foods Of The Nine-Banded Armadillo In Floridaa

The foods of 172 armadillos from the recently established Florida population wer,e compared with foods of the native population as reported by various authors. Some differences were observed, but the foods of armadillos in Florida were quite similar to those reported for the species from its native U.S. range. Seasonal variation in the consumption of Coleoptera, Diptera, Lepidoptera, Hymenoptera, Myriapoda, and Annelida were noted.

Foods of White Ibis from Seven Collection Sites in Florida

Between 1970 and 1973, 180 white ibis (Eudocimus albus) 140 adult and 40 nestlings, were collected from four fresh water and three salt water sites and their stomach contents identified. Crustacean and aquatic insects were the major food items totaling 86.4% of the total food volume. Differences exist between stomach contents of ibis collected from fresh water and salt water habitats. Those collected from fresh water habitats contained more insects and snails while those from salt water sites contained more insects of certain families and crabs.

Foods of Young Florida Wild Turkeys

Stomach and crop contents of 75 turkeys (Meleagris gallopavo osceola) poults from 1 to 164 days old and 8 adults, collected from April through October in Glades and Alachua Counties, Florida, were identified and measured by volume displacement. Vegetable material accounted for 75.0 percent and animal material for 25.0 percent of the diet by volume of poults 1 to 14 days old. Poults 15 to 164 days old ate 72.8 percent vegetable and 27.2 percent animal foods. The most important single item in the diet of the I to 14 day old group was "stargrass" (Hypoxis leptocarpa) - this was replaced in...
