A Tiny Endangered California Least Tern: How Bird Banding Helps Conservation
Meet a young endangered California Least Tern photographed in Carlsbad and learn how bird banding helps researchers track survival, movement, and conservation.

A tiny endangered seabird—and an important reminder of why protecting our coast matters.
This young California Least Tern, photographed in Carlsbad, is part of a species fighting for survival along California’s coast.
The California Least Tern is federally and state listed as endangered—a designation that reflects how vulnerable this species remains and how important continued protection is to its survival and recovery.
Least Terns nest on open sand and other sparsely vegetated coastal areas, making their eggs and chicks especially vulnerable to habitat loss, human disturbance, dogs, and activity near nesting colonies.
Look closely at this little bird’s legs: she is wearing a green research band and a federal metal band. Bird banding helps biologists learn about individual birds—their survival, movements, breeding history, and connections between nesting colonies—providing valuable information for conservation.
California Least Terns can live for many years, with some banded individuals documented surviving for more than two decades. That means a tiny band placed on a chick today can potentially help researchers follow her story for years to come.
For an endangered species, every single successfully raised chick matters. Protecting nesting habitat, respecting posted closures and fencing, keeping dogs away from colonies, and giving birds plenty of space can make a meaningful difference.
This precious chick was photographed from a distance through protective fencing, allowing her to remain undisturbed.
Every nest matters. Every chick matters. Every protected stretch of habitat matters.💚

Meet Opal the Western Gull
Meet Opal, the Western Gull chick, when she was just about a week old. 🤍
We’ve spent countless hours in the field observing and helping protect Opal and her family since she was still an egg. This photograph was taken in June 2026. 💜
Watching Opal grow from a tiny chick into the beautiful fledgling she is today has been incredibly special—and a reminder of why every effort to protect vulnerable wildlife matters.
Opal is now one of the precious wild lives featured in our Jewels of La Jolla educational art collection, celebrating the remarkable wildlife that makes this coastline so magical. ✨

EYES Community BIRD WALK, National Bird Day JANUARY 2026
Some of the magical Bird Jewels we had the delight of observing included Brandt’s cormorants with their striking turquoise eyes, the adult California brown pelican with sky-blue eyes and a vibrant red throat pouch, and the majestic Black Oystercatcher with its bold orange bill and eye-ring. We also enjoyed the intelligent, charismatic Western gull, the precious Heermann’s gulls, and the elegance of Royal and Elegant terns, crowned with their distinctive head crests.

We identified an injured Heermann’s gull, documented what we observed, and reported—reminding us that careful monitoring and timely reporting can help save lives. Every wildlife life is precious. 💙 We will share more about her and the other injured wildlife including 2 entangled sea lions that we spotted during our walk through the Wildlife Jewels Rescue Blog soon.
A Second Chance for an Entangled Brown Pelican. One moment of awareness helped change the course of his life. On July 22, 2026, a Wildlife Jewels® Search Scout survey at Crystal Cove State Park became an unexpected rescue mission.
