Nice capture,
but it doesn't look to me that he is watching you from the way the
light is hitting his eye... he looks like he is ignoring you :-)

IIRC, the field of view is nearly 180 degrees. The fovea (area of
greatest sharpness on the retina) is way off-center so that it is
still engaged when looking ahead. I also recall reading that raptors
have the equivalent of 20/4 vision, and it includes UV.

Another sparrow, shot at a modest 1/80th second shutter speed and an ISO of
about 1500. That seems to be a fast enough shutter to yield sharp results if
the bird is perching. This is with the DA 1.4X converter and the D FA 150-450.
The stop is f8 and the focal length is 630 mm.
I always wonder what the bird’s field of vision is like. They must see more
than 180 degrees.

They must have good vision around here, as the cat population is so high. Great
image, make the use of the warm weather whilst you can, the temperature has
dipped noticeably here.
