Field Trip Report: LAB-S at LA River 8/9/2025

By Miles

This Saturday morning LA Birders – Students held a field trip along the Willow Street stretch of the Los Angeles River, with 8 birders attending, including 6 students!

It was a sunny day and birds were flying and foraging all along the river. We started off by scanning the section right next to the entrance to the bike path as we waited for more birders to join. With two spotting Scopes (Adam and Surya both brought a scope!) working together, the common shorebirds were soon spotted, Stilts, Avocets, Dowitchers, Sandpipers, Yellowlegs, Gulls, Terns, Ibises… Even a Wilson’s Phalarope and a Lesser Yellowleg were found foraging on the riverbeds!

Once everyone arrived, we started to walk south along the river, which had more trees and bushes, but less muddy areas and shallow waters for the shorebirds. The growth of vegetation led to more Passerines, with other flybys and a few more waterfowls our list was quickly brought to more than 50 species.

On the way back, a couple of cormorants started to fly around and we started to try for a Neotropic and finally we got it resting on a rock in the water just south of Willow Street.

After crossing the Bridge’s tunnel we got back to our starting point and scanned through the river for some more shore birds. Finally, after a super close osprey flyby. A Ring-billed Gull (new species to our list for today’s trip) was spotted.

As there is still a lot of time left we started to scan through the peeps to see if we can find any rare ones. I started to take pictures for every peep as usual and got one peep that is as big as a Western but has different color patterns. After we used merlin and compared it with other photos, we decided it to be a Semipalmated Sandpiper. But later after checking with Dessi, we changed the identification to a big Least Sandpiper.

Even though the peep didn’t get confirmed, it was still a wonderful trip! After Charles went through the checklist he kept for the trip, we found that we are at 60 species (59 after deleting the sesa) !
