Sign up and confirmation notes:

If the Google sign-up form for the trip you want to go on doesn't work the first time, try reloading the web page or restarting your browser, then try again.

If it's less than 3 days before a trip that you signed up for, and you think you should have gotten a message but haven't, try looking for it (carefully) in your spam/junk folder.

If these suggestions didn't help solve the issue, please contact us at fieldtrips@pasadenaaudubon.org .

April 5th: Ballona Creek Walk

Sunday, April 5th, 2026
8:00 AM to 11:00 AM
Trip leaders: Kevin Lapp/Alex Sauerbrunn

Take a walk on the wild west side with Kevin Lapp and Alex Sauerbrunn! Ballona Creek, the adjacent beach, wetlands and lagoon are among the last remnants of LA’s estuaries. So it's a great spot to see shorebirds like Marbled Godwits, Surfbirds, turnstones, and plovers, along with other coastal specialties. Parking can be challenging, so early arrival is recommended, and carpooling is encouraged! We will determine a carpool spot for folks interested in ride-sharing, departing Pasadena at 7 am for an 8 am trip start.

Participant number: no limit.

DATE CHANGE! April 19th: Caltech Birdwalk

Sunday, April 19th, 7:00 AM – 9:30 AM
Trip leader: Jieyu Zheng

Turns out there is a major campus event on Saturday the 11th, large crowds expected, which would not be conducive to a bird walk.

Join Pasadena Audubon Society for a bird walk on the beautiful campus of the California Institute of Technology (Caltech). Led by current PhD student Jieyu Zheng, this walk will explore the surprisingly rich wildlife community found in the heart of Pasadena. We’ll look for resident species such as Acorn Woodpeckers, Black Phoebes, and Dark-eyed Juncos, as well as migrating songbirds that may be resting and re-fueling in the campus’s diverse trees, exotic shrubs, and open lawns.

TRIP LIMIT: 30 people. Participants will be chosen by lottery.

April 12th: Los Angeles Arboretum Monthly Bird Walk

Sunday, April 12th, 2026

8:00 AM - 10:00 AM
Trip Leader: Catherine Hamilton

We are excited to partner with the Los Angeles County Arboretum to offer free monthly bird walks to PAS members. Please note that due to new rules implemented by LA Arboretum these trips will only be open to current PAS members (and not friends of members as in past years). In other words all persons attending must be current Pasadena Audubon members -- either on their own, or as part of a PAS family membership.

Not a PAS member? Join here!

This field trip is offered by reservation only. To reserve a spot go to https://www.arboretum.org/events/bird-walk-with-pasadena-audubon-8/. Registration is scheduled to open at 9 AM on Tuesday, April 7th, 2026.

SPECIAL NOTE ABOUT REGISTERING FOR THE ARBORETUM WALK: Evidently when the monthly Arboretum walk has reached capacity, the sign-up form stops functioning correctly. This issue is beyond our control. If in doubt, sign up early!

April 15th: Midweek Birding Group- Bear Divide

Wednesday, April 15th, 2026
8:00 AM - 11:00 AM

Leader: Ed Stonick

Join veteran birder Ed Stonick for a midweek trip (when it's less crowded!) to Los Angeles’s hottest spring birding spot, Bear Divide. Here, in spring migration, thousands of birds are tallied in what is often referred to as morning flight - a phenomenon where mainly nocturnal migrants move for a few more hours or perhaps reorient themselves early in the morning (no one really knows for sure). As well as watching this incredible phenomenon, we will visit with the counters from UCLA and Occidental and head to the bird banding station there on site. The Bear Divide count is sponsored by Pasadena Audubon Society.

Participant number: No Limit.

Trip details such as meeting location will be emailed to signed-up participants 2-3 days before the trip.

April 25th: Huntington Library Monthly Bird Walk

Saturday, April 2th, 2026
8:00 AM - 11:00 AM
Trip Leader: Mark Hunter

This is a great walk for beginning birders and families, with easy walking and a nice variety of species present year round.

The Huntington Library is allowing a limited number of Pasadena Audubon members to enter the grounds for this walk without being Huntington members (thanks Huntington!). You must be a Pasadena Audubon member to attend this trip! Not yet a member? Sign up for PAS membership here and then return to this page.

By the way, if you are also a member of the Huntington please also sign up for a reservation on their website. That way your attendance won't count against the limited number of passes the Huntington has given us here at PAS.
