Phenology

Observations by Gary Fewless for Green Bay WI (Lat.N 44.51° Long. W 88.02° ), except as noted. For flowers lacking conspicuous petals or sepals I define "anthesis" as release of pollen by mature anthers.

Date	Observation (Click on links for photos)
Sep28	In spite of the frost the leaves remain remarkably green for this late in the season. Even the sumacs, ordinarily one of the first to turn color, are only partially red.
Sep25	First official frost of the Fall, City GB. First scraped windshield of the season!
Sep24	Clear and cool with steady NW winds. The first Ring-necked Ducks of the year. Also on the point were Ruddy Turnstones and Sanderlings. A large flock (83) of Bonaparte's Gulls was seen out in the Bay. Good numbers of Ruby-crowned Kinglets and Winter Wrens signals the onset of the late fall migrants. Golden-crowned Kinglets can't be far down the road. Tom Erdman.
Sep21	Clear and cold with a steady wind from the NW. The first flock of Lesser Scaup was seen out in Green Bay. Blackpoll, Magnolia, Nashville, and Tennessee Warblers made up the bulk of the migrating passerines. In addition, White-Throated Sparrows, Winter Wrens, Red-breasted Nuthatches and Brown Creepers were also spotted. Andy Paulios.

Season's first Yellow-rumped Warbler and Ruby-crowned Kinglet. Two Cooper's Hawks were hunting in the lagoon. Bald Eagle, Red-tailed Hawk, and (possibly) Merlin also were recorded.
