As I work on bird in flight photography, I am having a bit of a love affair with Northern Harriers. They are as hawks go, fairly accommodating for the photographer. Their habit of gliding low to the ground over marsh land makes them much easier to photograph than say a high flying Red-tailed hawk.
I discovered that the Swan Lake nature study/refuge area north of town is a favorite haunt of these birds. The refuge is just under 2000 acres and surrounded by warehouses and neighborhoods. They built a long dock-walkway out into the middle of the marsh and standing on this puts you right in the middle of the action for Harriers as they hunt.
Northern Harriers are easy to identify. They have an owl shaped face. This shape helps funnel the noises of voles and mice to them which are their principal prey. The females are brown in color and the males are grey to white.
There are quite a few of these hawks frequenting the swamp. I hope the action continues through the year. They are fun to practice flight photography on and beautiful to watch.
