August 31, 2010 Birding along the Ottawa River from Britannia Point to Andrew Haydon Park

Despite the recent heat wave with a 42+c humidex, the birding along the Ottawa River was good this morning. Our first stop at Britannia/Mud Lake produced a number of warblers along the ridge including Northern Parula, Chestnut-sided Warbler, Yellow-rumped Warbler, American Redstart, Black-throated Green Warbler, Yellow Warbler, Tennessee Warbler, Common Yellowthroat, and Wilson's Warbler. At Deschenes Rapids there was a good concentration of gulls which included 46 adult Great Black-backed Gulls. As the day heated up bird activity quieted down and a walk around Mud Lake produced 1 Black-crowned night-Heron, 3 Pied-billed Grebe, 20+ Wood duck, 2 Green Heron, 4 Great Blue Heron and 3 Hooded Merganser. At Andrew Haydon Park we observed 6 juvenile Baird's Sandpiper along with 1 Semipalmated plover, 2 Semipalmated Sandpiper and 4 Least Sandpiper. There was 1 Great Egret feeding at the west end of the park.

Direct size comparison is very important aid when identifying shorebirds.

A juvenile Baird's Sandpiper feeding, note the long winged appearance.

Another good aid in identifying Baird's Sandpiper is the very horizontal look when feeding.

Note the pale feather edgings on the back of the Baird's Sandpiper.
