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.

Green Bay Shore

Nov 30

Ice cover is off or nearly so for small streams and ponds in the Green Bay area. Overnight lows remained above freezing overnight and warmer air is approaching, so any remaining ice will likely be gone in the next few days.

November 2012 was 2.1° F warmer than average, and the precipitation of 1.05 inches (as water equivalent) was about one half of "normal" for the month.

Other plants are still flowering too, including this dandelion (Taraxacum officinale) at UWGB.

Pine Grosbeak Pine Grosbeaks have been steadily moving into the state in small flocks. This is a taiga species which is considered an irruptive winter visitor across the Midwest and East.  The last really large widespread movements into Wisconsin were in 1977 and again in 1985. They love to dine on crabapples, high bush cranberries, left over apples in orchards, sumac, mountain ash, and seeds of the box alder--stiff competition for Bohemian and Cedar Waxwings who also like the late fruits.  Besides the Pine Grosbeaks, good numbers of Siskins, Redpolls, Purple Finch and flocks of Evening Grosbeaks are also being recorded. The Pine Grosbeaks will eventually be coming to feeders with black sunflower seeds, but for now, it is find the fruit trees first!!
