Killdeer arrived back in northern New England last month and have already begun nesting. Being a ground nester, the killdeer has many mammalian predators from which it needs to protect its eggs, including weasels, skunks, opossums and raccoons. Nesting killdeer have a number of responses to predators, which include several different types of distraction displays which draw attention to the bird away from its nest. One of the most common displays is to feign injury by assuming a position which makes the bird appear vulnerable. When a predator approaches, the bird runs away from the nest, crouches with its head low, wings drooping and tail fanned and dragging the ground to display its rufous rump-patch. The predator typically follows, seeing an easy meal, and as soon as it gets too close for the killdeer’s comfort, the killdeer continues to lead it off by alternate flights and sprints.
The relatively warm, wet start to winter has provided us with the opportunity to see riverside tracks that might otherwise not be evident. Raccoons are known for their ability to go anywhere and get into anything and the reason for this dexterity is revealed in their tracks. Both front and hind feet have five long toes. Although the “thumb” is not opposable, it is long enough to grasp things. Because of this dexterity, raccoon tracks can vary widely. In mud and snow, they often resemble small human hands. Typically the toes of the front feet are more splayed out than those of the hind feet.
