I’m quite sick of summer. The long, hot days and blindingly bright sun have overstayed their welcome. I’d like to think the birds are annoyed with summer as well. They are mostly silent these days, with the exception of the starlings practicing their cover songs. Birding over the summer has largely been uneventful.

As I trudged through June and July, I kept looking to August for a bit of relief. No, it’s not cooler in August by any means. But the birding excitement starts to pick up – it’s sandpiper migration! These tricky little birds offer an advanced lesson in bird ID, and when you’re in the midst of a Big Year, it’s time to learn (and refresh your memory) fast.

In San Joaquin County, some of the best shorebird spots are around the Delta and water treatment plants. On mornings or evenings that were “cool” enough, we would venture out to the appropriate habitat and carefully review each peep (little sandpipers). Least Sandpipers and Killdeer offer good anchor points for IDs. The Leasts are the tiniest of our peeps while Killdeer are easily recognizable with the double-rings on their breast, red eyes, and persistent calls. From there, you can compare peeps in question with the Leasts and Killdeer based on size differences, bill shape, breast streaking, and sometimes leg color.

No matter how much I study, I cannot absorb the ID markers of a Semipalmated Sandpiper, which is a sandpiper that we need for the Big Year. It’s strikingly similar to the Western Sandpiper, the subtle differences being its overall size and its bill shape. Other peeps have more defined features to grasp, such as the Pectoral Sandpiper with its larger size and heavily-streaked breast, and the Baird’s Sandpiper with its long primary feathers that uniquely extend beyond its tail. These are solid structural features, not subjective features that require experience with the species – hard to do when it’s rare like the Semipalmated Sandpiper.

After many days spent in the hot sun looking through all the sandpipers, we finally spotted all the expected species that come through the area during August plus some bonus species, including the Semipalmated Sandpiper, Baird’s Sandpiper, Pectoral Sandpiper, Solitary Sandpiper, and Stilt Sandpiper. As the month – and therefore summer – finally comes to an end, our visits to sandpiper habitat will soon shift to looking for warblers and other fall goodies in wooded areas.

This morning was pleasantly cool, and the sun cast an orange glow through the trees. Fall is almost here, and I can’t wait!
