Specify Alternate Text
If you have an interest in migratory upland birds – as a hunter, a birdwatcher or just a citizen scientist – there’s a unique volunteer opportunity coming up that will allow you to work hands-on with wildlife, while helping the California Department of Fish and Wildlife collect critical research data that will become part of a national database.

One Step Closer to Reestablishing a New Population of Endangered Winter Run Salmon

Specify Alternate Text
Habitat is the key to the long-term survival of Sacramento River winter-run Chinook in California. Since 1999, CDFW has been working with multiple agencies and private parties on planning efforts to restore the population of these endangered salmon. More than $100 million has been allocated to specific habitat restoration work on Battle Creek, which comprises approximately 48 miles of prime salmon and steelhead habitat.

It does not take a leap of faith to believe that CDFW scientists have gained the upper hand in bolstering the population of yellow-legged frogs in the High Sierra.

The Challenges of Studying Roosevelt Elk

Specify Alternate Text
For residents of Humboldt and Del Norte counties, the majestic Roosevelt elk is a common sight. Although Roosevelt numbers were dwindling in California by the 1920s, conservative management strategies and limited hunting opportunities have helped them to rebound. Today, researchers have identified more than 20 distinct groups of elk in these two counties, many of which consist of well over 50 animals.

Badly Burned Ursines Get Back on their Feet – Thanks to Teamwork and Fish Skin

Specify Alternate Text
Two talented veterinarians, an environmental scientist and several dedicated staff members at the CDFW Wildlife Investigations Lab recently put their heads and their resources together to help heal a pair of adult bears that were badly burned in the Thomas Fire. The bears, which were treated at the same time as a young mountain lion with similar, less severe burn injuries, were released back to the wild last Thursday, after several weeks of intensive – and unusual – care.

Study of Songbirds’ Calls Provides Important Climate Insight

Specify Alternate Text
Two avian researchers recently completed a groundbreaking study on the effects of climate change, based on the calls of California’s songbirds. By recording the sounds made by eight different songbird species, and tracking the dates they are most vocal and how frequently they sing, the scientists were able to develop a method to measure how the birds are adjusting to climate change.
