I don't do much birding, but if I did, this is probably where I'd do it...

Burrowing owl at the Sonny Bono Salton Sea NWR. We were driving by on a dirt road when this guy was standing on the berm checking us out. It took a split second to grab the camera and shoot a couple of shots out of the car window before he flew off.

The snowy owl that supposedly hitched a ride south on a freighter from Alaska and ended up in Southern California. It caused quite the stir in local and regional birding circles. Luckily, we were on a birding trip to the Salton Sea and San Diego and popped into the LA area to see it perched on somebody's roof. Never expected to get this lifer this way lol....

I've just returned from a tree week vacation to Sri lanka and my EF100-400 f5.6 LIS II was my long tele of choice. I only reached fro my EF 400mm f2.8 LIS II when I needed something a bit more specific.
I pretty much had my EF 1.4X TC III attached all of the time and the images and image quality I've had from this combo has been exceptional. I have a number of protfolio worthy images from this lens on this trip and at time I had to look up in the exif which lens I'd used becuase from a sharpness point of view, this combo easily out resolves my R6ii. I can see no sharpness difference between this lens and my EF 400mm f2,8 LIS II, both lenses out resolve my R6ii's sensor by some degree. I love the contrast and colour fidelity from this lens too.
