We have been having a lot of hawk and owl activity at the pond. I am not sure if this is due to it being spring or due to corn.
I have noticed that the corn which the ducks do not eat, attracts birds, squirrels and chipmunks. I am sure that other creatures like mice also are drawn to the pond for this tasty treat.
I have seen the hawks and owls sitting on a tree limb above the pond. The hawk has been spotted sitting on the ground at the edge of the pond (presumably eating something warm and furry for breakfast). It seems that these birds are smart enough to understand that the pond provides ample dining opportunities.
