Wildlife Damage Management Technical Series
Rose-ringed parakeets (Psittacula krameri; hereafter RRPA; Figure 1) are an invasive species in the United States, present in Alabama, Louisiana, Texas, and Virginia, and with established populations in California, Florida, and Hawaii. They are also the most successful species of invasive parakeet, worldwide. RRPA can cause significant damage to agriculture, including grains, oilseeds, fruits, and ornamental plants. Large flocks of RRPA roost near human infrastructure resulting in concerns about human health and safety (e.g., collisions with aircraft, disease transmission, feces accumulation, and noise complaints). The population growth and spread of RRPA is of conservation concern given the potential impact on …

Wildlife Damage Management Technical Series
Prevention and control of cedar waxwing (Bombycilla cedrorum) damage to small fruits such as blueberry, cherry, and strawberry is vexing to growers in many parts of the United States. Cedar waxwings (Figure 1) travel in flocks and descend in large numbers on berry crops, especially during winter and migration. In short feeding bouts, waxwings eat, peck, or knock substantial amounts of fruit from the plants. These frugivores are difficult to discourage once they become established at a given location. Harassment early and often using pyrotechnics or other sudden noisemakers can help prevent flocks from being established. The most effective preventative …
