CWA’s waterfowl and wetland programs strive for abundant habitat and thriving waterfowl populations in the state, both local and wintering.

We leverage member contributions to obtain major public and private grants that enable us to do thousands of acres of habitat work every year. We leverage the passion of our members to run programs that make a real difference to California’s breeding population of wood ducks and mallards.

And our dedicated staff works up and down the state to band California’s iconic pintail and mallards. This contributes to research that supports our science-based system of hunting seasons lengths and bag limits — the very thing that ensures hunting remains sustainable, and never threatens the health of waterfowl populations.

CWA spends millions of dollars on wetland improvements projects on thousands of acres in California every year. Our projects reach across the state, from the Klamath Basin in the northeast to the Imperial Valley near the Mexican border.

Our project managers work hard and work smart to improve the capacity of California’s remaining wetlands. Meanwhile, our advocacy team advocates for adequate water supplies and habitat-friendly legislation.

One hundred years ago, wood ducks were on the brink of extinction. They rebounded, but the riparian habitat they require for breeding didn’t, so they needed help.

CWA began coordinating a state-wide citizen science project, deploying wood duck nest boxes across the landscape and volunteers who monitored how ducks used them. In 2016, the 750,000th wood duck duckling leapt from a CWA nest box.

The program also includes education opportunities, with fields trips where children are offered an array of hands-on, engaging activities geared towards wood ducks.

Wild mallard nesting habitat – dry fields with good grass cover near water – is in short supply, so ducks in California often nest in farm fields. Sometimes it goes well; other times broods don’t hatch before farmers need to harvest, mow or disk.

The egg salvage program deploys volunteers to collect eggs, which are then incubated. Ducklings are raised to five weeks, then released into the wild. Some get banded by youth during educational events.

The program bands and releases thousands of ducks every year, creating from nothing a sizable addition to the wild duck population.

California Waterfowl, with partial funding from the California Department of Fish and Wildlife, bands thousands of ducks every year to provide California-specific data used to assess waterfowl populations.

We focus primarily on mallards and pintail, the latter being the most numerous duck in our state each winter.

Our banding efforts help biologists understand waterfowl populations, movements and health, while providing a tool for wildlife agencies to set accurate, science-based bag limits and season lengths.

Boots on the ground will never be enough to support waterfowl and wetlands if California doesn’t have a legal and regulatory environment that’s friendly to waterfowl and wetlands.

So our advocacy team works year-round with local, state and federal governments, as well as regulatory agencies, to ensure promote policy that helps wetland managers and farmers do what’s best for wildlife.
