Bewick's Wren-Habitat

On my way home from my trip to the Klamath Basin I stopped at a little rest area between MP 142 & 143 on I-5 in Oregon. A small picnic area in the back had some paths through an oak grove. I found several Williamson's Sapsuckers (no decent images) and this Bewick's Wren foraging while I took a 10 minute stretch break. I was shooting hand held under overcast skies and only managed two decent shots of the wren-both in this position with just a different head turn.

1Div, 500mm f4 ISL + 1.4TC, hand held, f9 (should have gone wide open for this, though it would have blurred the surroundings a lot), 1/125, iso 1250, Av mode with +1/3 stop compensation. Processed in LR5 & CS6. I removed some distracting twigs above the wren, but left the stuff to the sides as I liked how it framed the bird and provided habitat. Cropped to 7.1 MP from a horizontal original. Taken at 10:47 am on February 22nd under cloudy skies.

Your comments and criticisms are very much appreciated.

Thanks for looking,
