Hi Ontbirders, About 25 of us had a pleasant day birding in the west end of Ottawa. We started at Mud Lake (Britannia) at 7:30 am and worked west to Andrew Hayden Park, Shirley's Bay, Constance Creek and finally Carp Ridge. We recorded 85 species. The highlight was our first stop at Mud Lake where we had an excellent warbler flock (most of the 16 warbler species that we saw today were there). Estimated warbler numbers for the day were: Tennessee Warbler 4, Nashville Warbler 3, Northern Parula 7, Chestnut-sided Warbler 3, Magnolia Warbler 4, Yellow-rumped Warbler 140, Black-throated Green Warbler 35, Blackburnian Warbler 2, Pine Warbler 1, Palm Warbler 1,Bay-breasted Warbler 2, Blackpoll Warbler 30, Black-and-white Warbler 4, American Redstart 1,Common Yellowthroat 1, and Wilson's Warbler 1. Non-warbler highlights here included 2 Black-crowned Night Herons and 1 Rusty Blackbird. There were very few shorebirds around. 8 Sanderling at Andrew Hayden Park were the only species of interest. The only other bird there of note was a single Bonaparte's Gull. Shirley's Bay was quiet with the only highlights being Scarlet Tanager and 15 Great Egrets. The melanistic chipmunk put on a show for everyone though. Further west we saw 7 Eastern Bluebirds along 6th Line, 10 Common Moorhens at Constance Creek (at Thomas Dolan Road) and 7 Purple Finches and 3 Field Sparrows at Carp Ridge (off Thomas Dolan).
