Hermit Thrush?

This is a new one for me. Is it a Hermit Thrush?

Photo was taken on November 30, 2014 in SF Bay Area, California, USA.

Thanks!

Yeah, the Sigma 500mm f/4 OS prime is long overdue. When Canon introduces the 500 f/4L II next year, they will probably increase the price by at least 50%. This should create an excellent opportunity...

It is strange that Canon chose not to use the excellent 1/2.3" 10MP CMOS sensor that is used on SD4000 IS and SD4500 IS for SX30 IS. I am hoping for a SX3 IS variant with that sensor...

The new SX30 IS

This is what Canon claims. The earlier non-L EF 70-300 IS had a more effective image stabilizer than the 100-400L and the newer EF 70-200 f/4L IS had an even better IS system, so it should be fair...

What type of Wren? (Northern California, USA)

I was only able to capture this single shot. It is not the best angle, but upon visual observation, this bird had a very short tail (almost no tail at all). What kind of wren is it?

As others suggested, 10-22 is a good choice as 17-85 has a bit too much distortion on the wide end.

While they are at it, they might as well make it a 400mm f/5.6 APO HSM OS.

Adding OS to the Bigma (50-500 HSM) would be a very good upgrade as well.

However, there are a couple of areas where Sigma...
