It was hard to know where to point the camera in the park, especially at end of day in the area aptly called the 'flight deck'. After a number of so-so images of birds on the ground I was back to playing with birds in flight, and eventually racked the zoom all the way to the wide end to get a wider aperture. The sun was almost down and the sky colors here are slightly accentuated, as is the foreground brightness to just show a few of the many birds also on the ground.
