Long distance fliers from the north spend much of the winter at Salt Plains National Wildlife Refuge and Washita NWR in western Oklahoma.
Snow geese prepare to land on a wheat field in Washita NWR on 12-18-2013.
These are all snow geese, but the one on the right is a juvenile, blue morph. Photo made at Washita NWR on 1-2-2014.
The two birds at the top are adult, blue morph snow geese. Until recently the blue morph variant of snow goose was considered to be a separate species known as blue goose.

Thousands of snow geese take wing after feeding on a wheat field at Washita NWR. It is not uncommon for 50 or 60 thousand of them to be on the refuge at one time.
This and the remainder of the images in this post were made at Salt Plains National Wildlife Refuge. This photo of snow geese, made just after sunrise on 1-13-2014, shows motion blur in the wing-tips due to the relatively slow shutter speed of 1/250 sec.
The warm color in this and the preceding and following images is a result of early morning light.
These are greater white-fronted geese. They are named for a small white area on the front of the head.
This photo shows Canada geese, sometimes incorrectly called Canadian geese, in the foreground and snow geese in the background.
These ducks are male common mergansers. The females have brown heads.
Sandhill cranes are very large birds, much larger than geese. During migration they can fly over 8,000 feet high with their 6.5 foot wing span.
Sandhill cranes fly in front of the moon at 8:42 in the morning of 1-20-2014. This image is not photoshopped by combining two images. The large size of the moon is a result of using a long telephoto lens.
These are greater white-fronted geese, with the exception of the second from the top, which is a Canada goose.
