On
July 16 and on July 26,
Carolyn Weng and I completed the first two
Shorebird Surveys for the fall 2012 season at the
Muskegon Wastewater. The
seven species encountered on
July 16 comprised
84 Killdeer, 84 Spotted Sandpiper, 5 Lesser Yellowlegs, 8 Semipalmated Sandpiper, 73 Least Sandpiper, 1 Pectoral Sandpiper, and 1 Short-billed Dowitcher. We also saw
two Northern Mockingbirds.
Diversity was higher on
July 26, when we recorded
13 species of shorebirds: 2 Semipalmated Plover, 62 Killdeer, 93 Spotted Sandpiper, 1 Solitary Sandpiper, 22 Lesser Yellowlegs, 1 Sanderling, 10 Semipalmated Sandpiper, 36 Least Sandpiper, 2 Baird's Sandpiper, 20 Pectoral Sandpiper, 2 Stilt Sandpiper, 1 Short-billed Dowitcher, and 1 Wilson's Phalarope. Notable non-shorebird tallies included
2 Common Ravens, 3 immature Orchard Orioles and 37 adult Sandhill Cranes.
This past spring we counted 896 shorebirds of 17 species during eight surveys from April 3 to June 15. Compared to the previous six years, diversity was slightly above average (15.7 species), and the individual total surpassed our previous high of 878 from 2006.
