Time to celebrate shorebird migration!
By Maureen Lahiff and Linda Carloni
Migration is always a natural wonder, whether of songbirds or Monarch butterflies or herds of caribou, but shorebird migration, following patterns from the Pleistocene, is truly an event to be noticed and treasured.
Now there’s even a special day to celebrate it – World Shorebirds Day, September 6, with global shorebird counts on the weekend of September 5-6!
First observed in 2014, World Shorebirds Day aims to raise global awareness of shorebirds and the challenges they face from loss of wetlands. It was founded by György Szimuly, also known as Szimi. He’s Hungarian, so he’s travelled to pursue his passion; he now lives in England. For more information, and some great photos and art, go to the website worldshorebirdsday.wordpress.com/.
San Francisco Bay is crucial for shorebirds
Even though more than 90 percent of San Francisco Bay’s original wetlands have been lost or seriously degraded by urban development, over 1 million shorebirds visit the Bay each year.

The Western Hemisphere Shorebird Reserve Network has designated San Francisco Bay as a Site of Hemispheric Importance – the network’s highest ranking of importance. According to the Southern Pacific Shorebird Conservation Plan (2003), the Bay Area holds higher proportions of the total wintering and migrating shorebirds on the U.S. Pacific coast than any other wetland. For 11 species, over half of the individual shorebirds counted on the Pacific Coast in a given season are found here. (That season is most often winter or fall, sometimes both.)
According to the conservation plan, there are 13 species for which the Bay shoreline is critical: Black-bellied Plover, Snowy Plover, Semipalmated Plover, Black Oystercatcher, American Avocet, Willet, Long-billed Curlew, Marbled Godwit, Black Turnstone, Western Sandpiper, Dunlin, Short-billed Dowitcher, and Red-necked Phalarope..
What is a shorebird, anyway?
Not all birds we see on the shore are classified as shorebirds for conservation and monitoring purposes. Gulls, for instance, are not considered shorebirds. One good description of a shorebird is a bird that feeds in wetlands by probing with its bill or picking up food from the surface. Many shorebirds such as curlews nest inland. Some sandpipers like Mountain Plovers are grassland birds — “grasspipers,” as Kevin McGowan of the Cornell Lab of Ornithology calls them. Not all shorebirds are limited to winter visits: Small numbers of Black-necked Stilts, American Avocets, Black Oystercatchers and threatened Western Snowy Plovers are here year round, though they can be difficult to find.…
