🦭🧪🦑🌎 After decades of recovery, Fur Seals on the Farallon Islands are facing a new challenge. Explore the images below (from left to right) to learn how the 2026 El Niño is affecting the colony. #FarallonIslandsNationalWildlifeRefuge

🦉🧪🌎 You’ve heard of Bird-A-Thon, but what about the Farallonathon? Since 1992, our Farallon crew has put their own spin on Point Blue’s annual fundraiser by hosting a week-long Farallon bioblitz! Year 34 highlights: a rare Cocos Booby, 2 great white shark attacks, and tons of migrant birds!

🦉🧪🌎💛 It's that time of the year again! Every fall, Golden-crowned Sparrows return to California from breeding grounds as far north as Alaska and Canada. We’ve tracked first-capture dates our Palomarin Field Station for decades! Any guesses on when we'll catch our first GCSP this season?

Bird banders are part of a rigorous training program, where they learn to capture birds safely and record data on each bird caught. The info collected allows us to understand how populations of birds are doing and in turn gives us insight into the health of the systems we research.

🦭🧪🌎 #FarallonFriday update: After tagging 75 California sea lion pups, our crew moved to West End Island and tagged 200 northern fur seal pups in just 4 days! Fur seal pups are smaller but much feistier, and more similar in attitude to gremlins than sea lions! #FarallonIslandsNationalWildlifeRefuge

Early-career bird banders are part of a rigorous training program, where they learn to capture birds safely and record data on each bird caught. The info collected allows us to understand how populations of birds are doing and in turn gives us insight into the health of the systems we research.

🌎💧🧪 Sierra Nevada meadows may be small, but they are critical for wildlife, water storage, and water quality. Point Blue Senior Meadow Ecologist Cody Reed joined researchers and conservationists to discuss how we can better understand and protect these ecosystems. Read more: shorturl.at/KXXyP

🦭🦑🧪🌎 We just tagged 75 California sea lion pups on the Farallon Islands. But why? By tagging pups with unique flipper tags, we can follow them throughout their lives and learn how climate change, El Niño & marine heatwaves affect the population’s growth and survival.

California sea lions bred sporadically on the Farallones for decades, but in 2010 the population began growing exponentially. In 2025, we counted a record 1,526 pups. This year, 1,420 pups were counted. A spring marine heatwave and severe El Niño may have contributed to the slight dip in pup counts.

🦉🧪🌎 Happy California Biodiversity Day! At Point Blue, preserving and promoting biodiversity is at the heart of everything we do. Today, we celebrate California’s incredible #biodiversity and recognize the role it plays in sustaining healthy, resilient ecosystems.

🌚🚨🦉🧪🌎 We’re back with another #FarallonFriday after-dark update! This time, the Farallon crew was focused on Ashy Storm-Petrels. Using mist nets deployed after dark, researchers safely capture, band, and collect valuable data from these elusive #seabirds before releasing them back into the night.

This work is especially significant because Ashy Storm-Petrels are a species of special conservation concern in California. About half of the population lives and breeds on the Farallon Islands, making the Farallones a critical colony for monitoring and conserving this species.

🌼🦉🦋🌿🦅 September in the San Francisco Bay Area is full of wildlife and wildflowers! From Golden-crowned Sparrows and Monarch Butterflies to American Avocets, Sharp-shinned Hawks, and Great White Sharks, there are plenty of seasonal highlights to spot this month. What are you most excited to see?

🦉🧪🌎 The #BirdReturns summer wetland habitat program just wrapped, and the results are in! This year, we provided habitat for dozens of species of breeding and migratory birds, including secretive species like bitterns and rails. Pictured: Least Bittern emerging from the marsh for a quick snapshot!

That’s a wrap on another #WesternSnowyPlover nesting season! We’re celebrating the collaborative conservation work driving this species’ recovery and a major milestone: in 2025 (the most recent survey), Western Snowy Plover counts reached 3,000 for the first time in 20 years. 💙🦉🧪🌎

Our work is strengthened by partnerships with SPCA Monterey County, Monterey Audubon Society, Point Reyes National Seashore, Point Reyes National Seashore Association (PRNSA), California State Parks, California Department of Fish and Wildlife, U.S. Department of Fish and Wildlife, and more.

🚨🌚🦉🧪🌎 Happy #FarallonFriday! The crew has been busy banding Brandt’s Cormorants! Since these #seabirds are active after dark, banding is a nighttime affair! Using mist nets, researchers safely capture, band, and collect valuable data from these birds before releasing them.

🌎🧪🗳️ Good news: the Senate approved a provision temporarily blocking an OMB rule change that could destabilize science funding. Nearly 500,000 comments were submitted, including from Point Blue and many of you. We hope this delay will allow time for the policy to be reevaluated.

🦉🧪🌎 Drying wetlands? Try shorebird buffet! At the end of the #BirdReturns summer wetlands program, temporary wetlands gradually dry. Fish, crayfish, and insects concentrate in the remaining pools, which attract masses of #shorebirds. Newly exposed mudflats offer a feast.

🦉🧪🌎 It's International Owl Awareness Day! From fluffy fledglings to watchful adults, Point Blue has been monitoring Northern Spotted Owls since 1997, collecting data on nesting activity, reproductive success, and population trends to better understand and protect this threatened species. 💙

🦈🧪🌎🦑 It’s #SharkWeek! We’re celebrating by taking a closer look at one of the Farallon Islands’ most iconic visitors: the #GreatWhiteShark! Learn more about these incredible predators, their role in the marine ecosystem, and how their annual trip to the Farallones helps us study them! ⬇️

👀🐦 Grab your binoculars…we’re going to the Novato Baylands! Conveniently located on the Bay Trail, the tidal wetlands of the Novato Baylands are an absolute hotspot for #birds, wildlife, and native plants. All photos by Dick Evans.
