I'll be keeping this update brief, as I am away from home and only have my cell phone.
Today went as well as I had hoped it would!! After a bit of a plan change that was out of the hands of anyone involved, I ended up sleeping at home last night and left before sunrise, tallying about a dozen species on the drive to Norfolk County in the morning, including a Pileated Woodpecker and a handful of Eastern Bluebirds. I had little trouble seeing the Smith's Longspur (mega rarity in Southern Ontario) by late morning, and also enjoyed about 700 Sandhill Cranes and a couple of Rough-legged Hawks in the process.
I then headed to Toronto to look for the Lark Sparrow (not as rare as Smith's Longspur but still a great bird for Ontario), where I met up with Josh Vandermeulen and Henrique Pacheco and only had to search for about 15 minutes before getting super views and photos of it in the sun! The three of us made a quick stop at the Burlington Lift Bridge to see a female (Queen?) King Eider before heading to Niagara-on-the-lake.
We hoped to turn up a Black-headed Gull among the Bonaparte's Gulls flying along the river to Lake Ontario to roost for the night, but the exceptional weather conditions likely had most of the gulls feeding further up the river right until dark, as we saw very few Bonaparte's fly by! No problem - the three of us will be spending some time birding Niagara this week!
I ended up identifying 36 bird species today, which is about what I expected. It was a great day with great company and great birds!
