Lark Sparrows are another common bird in the Theodore Roosevelt National Park. In a previous post, I described the odd, turkey-like strutting by male Lark Sparrows. I did not mention their odd behavior of passing a twig from the male to the female during copulation. Pairs often use other species’ abandoned nests (Martin and Parrish 2000). This sparrow is common in most parts of their western North American range. They barely reach southern Canada and they winter in Mexico and in the Southwest. They thrive in disturbed areas, like in heavily grazed or fallow fields. We saw it in North Dakota last July.
