DON'T TAKE THE BAIT! AntiCoagulant Rat Poisons KillMDAS brochure
Barn Owls - innocent victims of rat poison
Anticoagulant rat poisons currently on the market (such as d-CON) contain highly toxic chemicals which interfere with the blood's ability to clot, resulting in uncontrollable internal bleeding and death. In addition to rodents, other animals that feed on poisoned rodents are also poisoned!
Victims include baby raptors which consume food their parents bring them and baby mammals nursing on their mothers' poisoned milk. Native wildlife suffering from secondary poisoning include hawks, owls, coyotes, foxes and mountain lions. These animals suffer miserable deaths because of anticoagulant poisons.
Children and pets are also poisoned. According to the EPA, more than 10,000 children are accidentally exposed to rodenticides each year, and an estimated 7,000 pets are accidentally poisoned.
- National Park Service flyer explains how park and open-space use of compounds like Diphacinone in gopher and ground squirrel baits take days to kill the rodetns, leaving them easy prey for rodent-feeding predators. Once a predator feeds on enough posioned rodents, it dies from poisoning. Secondary poisoning works exactly as the Environmental Hazard labels on the products say it will:

WHAT YOU CAN DO
Successful rodent control consists of three elements: good sanitation practices, rodent-proofing structures and rodent killing.
- Practice good housekeeping in your environment.
Exclude rodents from your home by covering all gaps larger than ¼” with small-gauge wire mesh screening.
Don’t use d-CON or other anticoagulant rodenticide.
- Pick up bird seed waste.
- Don’t leave pet food out, and store seed and pet food in pest-proof containers with tight-fitting lids.
- Make sure garbage bags are tied tightly and secured, and close and lock dumpsters.
- Remove excessive vegetation, piles of debris and English ivy; replace with native California plants which offer wildlife habitat.
- Consider installing a barn owl nest box, but only if everyone in the neighborhood agrees not to use poison.
NEW! - Talk to Local Agencies responsible for parks and open spaces.
- Use snap traps for rodents remaining inside the structure. Hire contractors who will not use poison but revisit to check snap traps.
- Consider alternatives such as electronic traps (the “Raticator”) or a new third generation rodenticide TERAD3. Glue strips are not recommend, as they are inhumane and often trap other creatures.
- Make sure they are aware of the issues and the facts.
- Require them to explain their decisions, particularly if they claim to be a "Certified Green Business".
- Remind them that poisoning raptors is a felony enforced by the U.S. Fish & Wildlife Service.

Through Connecting People With Nature, MDAS sponsored an Eagle Scout project to install 2 Kestrel nest boxes to help recover Kestrel populations in Walnut Creek parks. The project was to be included in the nation-wide American Kestrel Recovery Program.
Unfortunately, this project could not be done as City of Walnut Creek refused to stop using rodent poison that was responsible for the demise of Kestrels in Parks and Open Space to begin with. American kestrels are very sensitive to the rodent poison Difacinone, found in gopher bait and ground squirrel bait used in Parks and Open space for rodent control.
FERAL AND FREE-RANGING FELINES: A Wildlife "Cat-astrophe" MDAS brochure
The domestic cat is a non-native and invasive species. An estimated 600 million cats live worldwide, with approximately 160 million in the US. The domestic cat reaches sexual maturity at six months. Reproduction can occur throughout the year, and one female can produce up to 12 offspring annually.
Cats are highly efficient, instinctive predators; even well-fed, they continue to hunt and kill wildlife. Worldwide they are responsible for the extinction of numerous mammals, reptiles and at least 33 bird species.
A January 2013 study conducted for the Smithsonian Conservation Biology Institute and the US Fish and Wildlife Service estimates that in the US each year outdoor cats kill 1.4-3.7 billion birds and 6.9-20.7 billion mammals, reptiles and amphibians. Studies show that as cat abundance increases, native bird diversity plummets.
HOW YOU CAN HELP
- Keep your cat indoors and encourage others to do the same.
- If you are unwilling to keep your cat indoors, do not attract birds.
- Do not rely on bells or declawing to prevent successful hunting; these measures are not effective.
- Spay or neuter your cat and don't feed other outdoor cats.
- Never abandon unwanted cats.

California Bluebird Recovery Program
Bluebirds! They carry the blue of the sky on their backs but have lost much of their natural nesting habitat. The Bluebirds and many other cavity nesting birds need our help by restoring spaces for their nesting and conservation. With such a goal in mind, the California Bluebird Recovery Program (CBRP) has undertaken to increase the help being given to the cavity nesting birds. Since 1994, CBRP has placed and monitored hundreds of nestboxes with successful results. If you are interested in being a nestbox monitor, CBRP will provide you with;
- Nestbox plans designed for several varieties of occupants
- Suggestions for placement of boxes
- Convenient forms for recording activity in each box
- Assistance for monitors
