Danger – Anticoagulant Pesticides

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!

Cats Indoors Program

The domestic cat is a non-native and invasive species. An estimated 600 million cats live worldwide, with approximately 160 million in the US. 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.

McNabney Marsh

Nestled between a busy freeway, railroad tracks, an oil refinery, a sewage treatment plant, a chemical plant, and a small community, McNabney Marsh has been one of the most productive wetland systems in the Bay Area, providing food and shelter for a wide variety of fish, mammals, birds and invertebrates. It is part of a much larger Peyton Slough Wetlands complex, a series of wetlands which includes Mt. View Sanitary District’s Moorhen Marsh plus other wetlands which drain a watershed covering more than 3,900 acres. Mt. Diablo Audubon also partnered with the Mt. View Sanitary District to host an Earth Day cleanup and bird watching event at McNabney Marsh on April 13, 2019.

Community Science

Scientists use information from these community science projects to get the “big picture” about what is happening to bird populations. The longer and more broadly these data are collected, the more meaningful they become in helping scientists investigate far-reaching questions.

Christmas Bird Counts

Every year MDAS participates in the National Audubon Christmas Bird Count. Chapter involvement in this popular community science project is one of our most significant contributions to promote conservation. The data is used in many important ways to determine the long-term health and status of bird populations across the continent.
