Twenty-two observers attended this joint Chicago Ornithological Society/Evanston North Shore Bird Club sponsored field trip to the Calumet Water Reclamation Plant in southeast Chicago on Sunday morning (18 August 2013). Like last year's trip, it was an absolutely gorgeous day for a field trip. We counted at least 186 individuals of ten shorebird species, compared with 318 individuals of ten shorebird species on the same trip last year. The main difference between this year's trip and last year's was the number of Least Sandpipers (135 last year, 40 this year), and Pectoral Sandpipers (80 last year, 5 this year).

Our best trip highlight early on was a single adult BLACK-BELLIED PLOVER, but after acting upon the recommendations of the Gyllenhaals, we revisited the same spot and found that 3 adult BLACK-BELLIED PLOVERS were present. Our biggest miss (in my opinion) was Baird's Sandpiper. On the other hand, Aaron Gyllenhaal may have a very different interpretation of our biggest misses...!

Our trip results are listed below. By my count, we found a total of 43 bird species at the plant (compared with 43 last year as well). Once again, a big thanks goes to the Metropolitan Water Reclamation District of Greater Chicago for graciously allowing our groups access to the plant.
