What happens if our raptors consume an OvoControl treated pigeon? We get this question at least once a week. The short answer is NOTHING!
It stands to reason to think that if a predator consumes an OvoControl treated pigeon, it would have the same contraceptive effect. OvoControl represents birth control after all, and the pigeons are medicated with the active ingredient, nicarbazin. Fortunately, however, the pieces of active ingredient in the pigeon will have no effect whatsoever on a raptor, other predator or even a scavenger. In order to be effective, the bird has to eat the bait, not the bird that ate the bait.
If you are interested in the chemical and biological details, please see the technical white paper entitled, "The Secondary Toxicity of OvoControl (nicarbazin) in Birds" pdf below.
OvoControl is a ready-to-use bait, dispensed on flat rooftops with an automatic wildlife feeder. This effective and humane technology is especially useful for managing birds in larger areas without having to resort to poisons or labor-intensive trapping programs.
