    Bobolink / Dolichonyx oryzivorus

    : Breeds. and late May-early Aug in sizeable grassy fields. The complex surrounding the Crooked Road/Norway Drive intersection is the epicenter of our population.

    : early/mid May-late May sometimes appearing in backyards. to early/mid Aug- late Sep, with a peak late Aug/early Sep and to early Oct in fields and marshes. Most often detected by call, a penetrating ‘pink,' as they fly overhead.Listen here.

    Miscellany: Bobolinks are remarkable in several respects. They have one of the longest migrations of any songbird with most wintering in South America south of the Amazon, and they are one of very few bird species that replace all their feathers twice in a calendar year. Most birds replace their flight feathers only once a year. Breeding males are also unique among North American birds in being black below and mostly light above, the reverse of the normal pattern.
