A look at the list of 60+ birds seen on the lower Los Angeles River (with apologies for the late posting.)
I doubt Mr. Gehry’s much-ballyhooed plans are going to impact this stretch of the river since it handles the greatest volume of runoff along the river’s winding course before emptying into the Los Angeles Harbor at San Pedro. Years of drought have allowed a rich mix of algae, plants, and tree to grow in the riverbed. The concrete riverbed then becomes a thriving stopover for migrating shorebirds each summer into the early fall. We should be able to bird this area with similar species and at least this success in the years to come.
We visited four areas to focus on specific species and were successful in finding all of our “target” species! Thanks to Richard Barth and Jeff Boyd for sharing their local knowledge so generously!
Spots visited: River North of Willow Street Bridge, River South of bridge, River North of Alondra in Paramount, DeForest Park, River South of Rosecrans. Start 7:30AM, end 12:50PM.
Due to the back-and-forth movement of flocks of peeps, Dowitchers, & Stilts, any bird count would tend to be inaccurate. We can however confirm the relatively rare two Pectoral Sandpipers, and the solo Baird’s Sandpiper as minimum counts. For those who would bird this section we recommend you pick a day like today with a lovely permanent overcast that made the experience much less perspirant for all of us birders.
