The INSTITUTE for BIRD POPULATIONS
SIERRA NEVADA BIRD OBSERVATORY

IBP’s Sierra Nevada Bird Observatory is an array of research, monitoring, and conservation initiatives aimed at strengthening bird conservation in the Sierra Nevada Mountains of California. We use cutting-edge science, long-term population monitoring, short-term surveys, and thoughtful conservation planning - often in close partnership with federal, state, and private land managers - to develop practical solutions to conservation and land management challenges. Our end goal is to help land managers safeguard at-risk bird species, ensure continued robust populations of common species, and promote good stewardship of the natural resources that birds require throughout the Sierra Nevada region.


Black Backed Woodpecker Photo Black-backed Woodpecker Ecology and Management of Burned Forests
IBP is working with the U.S. Forest Service to monitor Black-backed Woodpecker populations, conduct research to better understand the species’ habitat needs, and provide science-based input into managing recently burned forests so that Black-backed Woodpecker and other fire-associated species can thrive.
 
Great Gray Owl Photo Conservation of the Endangered Great Gray Owl
IBP is collaborating with multiple state and federal agencies, and private land owners, to conduct research that fills important information gaps about Great Gray Owl habitat needs, and to develop a statewide conservation strategy for the species in California.
 
Willow Flycatcher Photo Willow Flycatcher Conservation and Restoration
Willow Flycatcher numbers in the Sierra Nevada have declined greatly in the past century, and are still declining. IBP has an active program of research and conservation work aimed at safeguarding and restoring populations of this California Endangered Species.
 
Sierra Nevada National Park Photo Birds of Sierra Nevada National Parks
Using annual backcountry point counts, IBP is partnering with the National Park Service to track changes in avian abundance and distribution at Yosemite and Sequoia/Kings Canyon National Parks, and Devils Postpile National Monument.
 
Black Backed Woodpecker Photo Restoring Montane Meadows and Other Riparian Habitat
Montane meadows provide important habitat for many bird species in the Sierra Nevada, including several imperiled species. IBP works with land managers to assess meadow restoration needs, prescribe bird-friendly restoration approaches, and monitor the effects of restoration efforts on bird populations.
 
Bee Pollinator Photo Protecting Sierra Nevada Pollinators
Pollinators, such as hummingbirds, bees, and butterflies, provide critical ecosystem services but face many threats. IBP is working with the US Forest Service and others to better understand distribution and abundance of bumble bees and other pollinators in the Sierra Nevada, and to develop science-based recommendations for pollinator-friendly forest management.
 
Spotted Owl Photo California Spotted Owls and Wildfire
IBP is working with diverse partners to better understand the complex effects of fire on California Spotted Owls and their forest habitat.
 
Climate Change Photo Photo Climate Change and Sierra Nevada Birds
The changing climate has already affected Sierra bird populations in numerous ways, and changes are expected to accelerate in the coming years. IBP has an active research program to understand climate-induced ecological changes in the Sierra Nevada, identify bird species most at risk, and develop strategies to bolster ecological resilience.

IBP’s Sierra Nevada Bird Observatory is always looking for new partners and collaborative opportunities to facilitate bird conservation in the Sierra Nevada. For more information contact Rodney Siegel.
