单选题Sometimes an object in nature is so rare that it escapes mention in nature books. Such is the case with the delightful Kirtland's warbler. The Kirtland's warbler is a plump, yellow-breasted bird that can be found nesting almost exclusively in the upper half of Michigan's Lower Peninsula. Although this bird does migrate to the Bahamas during the winter months, Michigan is its natural habitat. Unfortunately, reduced numbers have caused the Kirtland's warbler to be designated an endangered species. The remaining Kirtland's warblers now enjoy living among the jack pine trees located in protected Michigan forests. The male warblers generally return north before the female birds. Often, they return as early as May. When they arrive, the male warblers stake out their territories and choose a nesting area. At the completion of their own long journey from the Bahamas, the female warblers begin to collect leaves and grass to build their nests. Oddly, the Kirtland's warbler nests on the ground and not in the nearby jack pine trees themselves. During the nesting process, the male warbler provides food for his mate while the female Kirtland's warbler lays four to five speckled eggs. The eggs hatch in two to three weeks and both the male and female warblers tend to their chicks.
