I was walking through the nature trail in Rowlett, Texas on a cloudy, overcast January day and saw this White-throated Sparrow.
I captured this image using a Nikon D700 camera with a Sigma 150mm to 600m mzoom lens attached.
The settings that I used were as follows:
Shutter speed 1/250 sec, f6.3, ISO 1600 and the lens was zoomed to 600mm.
