I had an excellent morning birding at Riverwood and the adjacent part of Erindale Park.
The highlight was a singing male golden-winged warbler (my 3rd this spring in Mississauga!!!). He was at the back edge of the little gravel parking lot on the right side of the main entrance road at Riverwood, and was chasing around a female blue-winged warbler.
Aside from the golden-winged and blue-winged warbler, other good warblers included 1 Northern Waterthrush, 1 Orange-crowned, 2 Mourning, 5 Parula, 1 Blackpoll, 2 Pine (on territory) and 1 Wilson's.
Most common species were Black-and-white, Tennessee, Nashville, Magnolia, Yellow, Chestnut-sided and Black-throated Blue, and I also had Ovenbird, Yellowthroat, Redstart, Bay-breasted, Blackburnian, Yellow-rumped and Black-throated Green in smaller numbers.
The non-warbler variety was much more limited in notable birds, but I did have 2 Solitary Sandpiper, 2 Lincoln's Sparrow, 1 Scarlet Tanager and good numbers of Red-eyed Vireo, Veery, Swainson's Thrush, Rose-breasted Grosbeak, Indigo Bunting and Baltimore Oriole.
