Like your Canada Warbler shot. I was at Britannia Conservation area late yesterday morning and there were LOTS of warblers up on the ridge. Most were Yellow-rumps but some saw Magnolia as well and a few I still haven't identified yet. Gotta look through the Sibleys.
There was even a Hummingbird.....first one I saw all season. It flew in from my right side. At first I thought it was a large insect but something about the flight told me bird. Sure enough, it was a Hummingbird and it was even sticking its tongue out at one point. Saw a Black + White warbler inside the woods right around that kite hanging in the tree. Too bad I didn't check the shutter speed because the shot ended up kind of blurred (would have been even more blurred if not for the IS on the 100-400L IS). The weather wasn't so good early in the morning but I got there late and this influx of warblers happened after 11am. It was pretty darn quiet and suddenly warblers all around. This went on for well over an hour.
Which naturalist are you referring to...Bruce or Tony?
I was there again today and the Yellow-Rumped warblers were everywhere. I also saw a Nashville and I got some shots of what I believ is a female Blackburnian Warbler. It matches in a few of my books perfectly. I saw Black and Whites a couple of weeks ago on the ridge but no luck photographing them. I also saw a White Throated Sparrow on the ridge this morning as well as the tamest Catbird I have ever seen...several other warblers as well that I can't identify...yet.
The naturalist I was referring to is Tony. I have sent shots to Elizabeth for identification and she has passed them on to Tony in a couple of cases. He confirmed the Juvie Virginia Rail for me. One of the guys at work is very knowledgeable as well and he is a friend of Bruce's..academic now as Dan id probably right..BTW...nice photo in the Ottawa Citizen yesterday. I bet you have a lot of great shots from that trip
Thanks Joe

Same has happened to me. Elizabeth sent an email I sent her to Tony as well. And he was very helpful. I can tell you one thing, Tony is a great guy to go bird with. I've run into him a few times while out taking photos. Very enthusiastic, friendly and knowlegeable. A generous guy too. I had planned to go with his group on a night owling excursion but couldn't make it. He offered to take me owling a few days later, just him and I. Unfortunately, I couldn't take up his offer due to work the next day (I forget what the reason was now).
