Our first stop was Hasting's Drive. We were greeted by lots typical late May migrants like flycatchers, thrushes and warblers like Tennessee, Wilson's and Blackpoll. We were walking along the road when we noticed a big flock (230 individuals) of Whimbrels heading west, then shortly after another flock (120). We're right in the prime time for Whimbrels moving through so we decided to head back to the car to do a proper lake watch with the scope. We were rewarded with a total of 865 Whimbrels plus 6 Red Knots (good Long Point bird) within the next hour and 7 Red-throated Loons. Here's our full checklist.

Sure enough it was a very interesting bird! My initial thought went to female Cerulean but the yellow on it made it obvious pretty quickly that wasn't correct. I'll let the photos speak for themselves:
The bird in question has a lot of features that point towards Magnolia Warbler, especially the back and rump, but there is lots wrong for that species - notably the pale head, throat and underparts and the tail (which should have white spots on the tail feathers rather than the white outer rectrices of this bird). Our best guess at the time was a Magnolia x Chestnut-sided Warbler hybrid but looking at the photos again I can see why Cerulean came to mind (check out that head/face) initially.
Magnolia x Chestnut-sided doesn't seem like too much of stretch since the two species share a lot of breeding range and often are found in similar habitat. Cerulean x Magnolia would be more of a stretch since those two species don't overlap a whole lot or share very similar habitat. What do you think? According to Birds of North America online the only confirmed hybrid involving Magnolia Warbler was one with a Yellow-rumped Warbler from Dominican Republic (Latta, S. C., K. C. Parkes, and J. M. Wunderle. 1998. A new intrageneric Dendroica hybrid from Hispaniola. Auk 115(2):533-537.). That combination is extra interesting to me because I am convinced I observed such a bird just a week and a half ago...see my description of it here.
Anyways, we made a stop at Townsend Sewage Lagoons on the way home where there was a good number of shorebirds (see our full checklist here) including a beautiful female Wilson's Phalarope. We ended our day at about 140 species, not too shabby!
If you're thinking about visiting Long Point be sure to check out the new Long Point Birding Trail either online or by picking up your copy at Bird Studies Canada headquarters or the Old Cut field station.
