I left my house this morning before sunrise hoping to get some Bluebirds in nice morning light , as the sun rose I was able to create this image , one of several that I'm pretty happy with, taken with Canon 20D w/ Sigma 70-300 APO DG Macro , F/8.0 @ 1/640 sec, ISO 400 Manual exposure
Everything looks good from the light, the colours, the comp, and the perch...except the head angle is not very desirable. Glad to see your using the extra reach of the Sigma.
