Silent spring for Bay Area’s raptors?
Rodenticide-related wildlife mortality may seem an abstract issue until your child finds two dead hawks in the backyard wading pool. That happened to Berkeley resident Dan Rubino on the Fourth of July in 2007. Rubino sought out his neighbor Lisa Owens Viani, who has a background in wildlife rehabilitation. She identified the birds as juvenile Cooper’s hawks, the offspring of one of 13 local pairs.
Owens Viani suspected rodenticide poisoning: “When Dan told me they were going to the pool, I knew right away what it was. I knew they would be bleeding internally and looking for water.”

Thus begins part one of the two part series describing the danger that second generation anti-coagulate rodenticides (SGAR) pose to birds of prey. See, folks use the poisons to kill rats, but the rats take a while to die. Raptors eat the toxic rats and get killed themselves. In 2003 the EPA responded to growing concern and litigation by requiring that SGARs would stop being sold to the public in 2011. They wanted them marketed only to wildlife control specialists, but that hasn’t exactly happened. In the mean time, children are finding cooper’s hawks in their wading pools.
So long-time beaver friend Lisa Owens Viani (formerly of SFEP and now of Golden Gate Audubon) has taken up the gauntlet and is marching city by city getting them to agree not to use or sell SGARs. She has started the aptly named organization Raptors Are The Solution (RATS) and is working hard to raise awareness. Go read the entire article and give RATS a thumbs up on facebook. This is just another example of narrow thinking having very broad consequences that cause unanticipated results. More vicious poisons to kill more rats leads to more raptors dying leading ironically to more rats because there are no more predators and the demand for even more vicious poisons to control a booming population. Repeat as necessary.
The article is written by Joe Eaton and Ron Sullivan. Joe wrote my favorite article about mother beaver’s death and is a long time beaver supporter. In March, we attended a St. Patrick’s Day Dinner with them at Lisa and Riley’s home in Berkeley, it was a wonderful evening with stories about bird watching, wildlife rescue, and city council struggles of epic proportions. Riley (author of the most famous creek restoration book and working on her second) is top tier of the water boards where people send really thorny problems. She told very amusing stories of a certain Hollywood royalty mogul in the Bay Area once asking for permission to fill in the creek behind his house with cement so his children could cross it easily to get to school!
Bridges are SO passe.
The second installation of the article comes next week and will talk about what citizens groups can do and are doing. Don’t miss it. I keep telling Lisa that RATS needs a booth at the Beaver Festival to raise awareness and connect with folks out here, but does she listen?
