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 .

June 6th: Breeding Birds of Hahamongna Watershed Park

Saturday, June 6th, 2026, 7:00 AM – 10:00 AM
Trip leaders: Van Pierzalowski and Kelsey Reckling

As part of the California Bird Atlas project's "Big Weekend", project founder and CEO Van Pierzalowski, joined by PhD candidate and veteran Bear Divide Bird Counter Kelsey Reckling, will lead participants around Hahamongna Watershed Park with the goal of documenting evidence of breeding birds. This is a great opportunity to learn about locating bird nests, determining that a bird is part of a breeding pair, and linking eBird observations to the California Bird Atlas.

Participant number: 20, determined by lottery. Sign up by 6pm on June 2nd.

June 13th: Butterflying For Birders

Saturday, June 13th, 2024
8:00 AM to 1:00 PM
Trip Leader: Luke Tiller & TBD

Join Luke for an exploration of the San Gabriel Mountains that will seek out some of the beautiful butterflies that call our local mountain range home. When temperatures rise and birds quieten down insects come into their element. Our trip will focus on looking at and identifying butterflies through binoculars rather than catching them. Butterflies need a little warmth to get themselves going in the morning, which means a slightly later start to this trip than average.

Participant number: 30, determined by lottery. Sign up before Tuesday, June 9th, at 6 PM. Trip details such as meeting location will be emailed to randomly chosen participants before the trip.

June 14th: Los Angeles Arboretum Monthly Bird Walk

Sunday, June 14th, 2026

8:00 AM - 10:00 AM
Trip Leader: Jieyu Zheng

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, June 9th, 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!

Saturday, June 20th, 2026

Participant number: 30, determined by lottery. Sign up before Tuesday, June 16th, at 6 PM. Trip details such as meeting location will be emailed to randomly chosen participants before the trip.

June 27th: Huntington Library Monthly Bird Walk

Saturday, June 27th, 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 at a level that allows you to enter the grounds at 8 am, please also make 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.
