Sometimes the Prey Bites Back

I hope you’ll bear with me but this post will be more about behavior than image quality as I just didn’t have a good light angle for this little drama.  As I’ve said elsewhere on this blog, one of my primary goals is to document interesting behaviors and at times that will take priority over the quality of the images.  When Rough-legged Hawks dive on prey it can be fairly dramatic.  Typically they hover high up over the potential prey for a few moments, then dive fast and at a fairly steep angle.  Occasionally they seem to hit the ground so hard that it rattles my teeth, almost making me expect them to bounce on impact.     1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc This morning I watched this hawk hover, then dive.  I think you can see from the wing position that this bird was still traveling at a good clip and at a fairly steep angle when it was only a couple of feet from the ground.   The prey was on a hill above me and buried in this vegetation so I didn’t see the impact.       1/2000, f/7.1, ISO 500, 500 f/4, 1.4 tc  Often these attempts at prey are unsuccessful but this time the hawk caught a vole (along with a talon-full of debris).   The bird came out of the grasses directly toward me but then turned to its left to give me a side view.     1/1600, f/7.1, ISO 500, 500 f/4, 1.4 tc  This little vole had a bucket-full of attitude and didn’t want to go down…

Rough-legged Hawk – Defensive Posture

Most birds are defensive of their territories and space and raptors are certainly no exception.  Rough-legged Hawks and Northern Harriers both prey heavily on voles (mice-like rodents) so when a new bird of prey comes in to the established hunting territory of another there are often conflicts, with the established bird attempting to drive off the interloper to avoid competition for food resources.    Rough-legged Hawk As I was photographing this Rough-legged hawk sitting peacefully in a tree I noted a definite change in its demeanor so I looked around and spotted a Northern Harrier speeding toward the hawk from my right.  I anticipated that the harrier would “buzz” the roughie and since I was much too close to get both birds in the frame when it happened I decided to concentrate on the reaction of the hawk as the interaction occurred.  I never did get the harrier in the frame in any of the shots.   In the image above, the roughie hasn’t yet seen the harrier coming in (nor have I).     The incoming Northern Harrier has been spotted When I noticed this posture change in the roughie I knew something was up, so I looked in the direction the bird was focused on and saw the harrier coming in fast.       Beginning to react Here the hawk is beginning to react to the swift and aggressive approach of the harrier by beginning to fluff up.       Defensive posture This shot was taken when the harrier, traveling very fast, was closest to the hawk – roughly three…
