“…Baiting has been used to control feral pigeons where habitat modification is not practical, and baiting has been an essential part of the program in the past. With the arrival of Cooper's hawks, the use of bait has been almost eliminated because of the potential risk to the accipiters (Holler 1982). This poses a potential problem because the Cooper's hawks may not provide as effective control, or control that is not effective enough.…”

Information concerning 19 species of birds associated with 28 buildings on the University of California at Berkeley campus has been collected for 25 years. Sixteen species are included under three minor associations (temporary roosters, building invaders, and species that nest on (or in) buildings in small numbers). Barn owls and ravens have caused intense, though localized problems. Two additional species (cliff swallows and feral pigeons) have caused major problems. Feral pigeons have caused the most difficult problems to resolve. Case histories are used to describe problems associated with these birds, and control strategies for them. Cooper's hawks have nested in central campus locations for the last four years and their contributions to pigeon control, interactions with campus buildings, and adjustments to their presence are discussed.

“…The access points are being screened, and all areas of the roof will then be accessible to raptors. Because of concerns about the potential secondary hazards of A vitrol ~ baits (Holler 1982) baiting has been stopped on the central campus area.…”

Secondary poisoning hazard of fenthion to American kestrels

The possibility that fenthion, an organophosphorus pesticide, could represent a secondary poisoning hazard to birds of prey was tested, using American kestrels (Falco sparverius) and house sparrows (Passer domesticus) as representative models of a naturally occurring predator-prey interaction. Fourteen kestrels were presented with live sparrows exposed previously to perches containing Rid-A-Bird 1100 solution (11% fenthion active ingredient). Eleven kestrels died within twenty-four h after consuming one fenthion-exposed sparrow. Two kestrels died after consumption of a second fenthion-exposed sparrow on day 2, and a final kestrel died after partially consuming a third fenthion-exposed sparrow on day 3. Brain cholinesterase (ChE) activity in kestrels was depressed to levels diagnostic of poisoning by a ChE-inhibiting compound. The majority of fenthion contamination of sparrows was external, with the highest amounts measured on the feet. The detection of fenthion residues in kestrel gastro-intestinal tracts confirmed secondary fenthion poisoning.
