||Observation (Click on links for photos)
||Leaf color is still
somewhat low key on the UWGB campus. There is some yellowing of leaves,
but many species are still green--the Red Oaks at UWGB in particular
are still fully green. The coming weekend will probably be the best
for fall leaf color north of Highway 64, and certainly north of Highway
70. Many geese are present in the fields in and around the Green Bay
||Low temperatures this morning
down to about 40 F in Green Bay and colder to the north and inland.
Frost predicted tonight (if not freeze). This should result in a rapid
turn of leaf color.

and Yellow-rumped Warblers commonly observed on Friday and
Saturday, T. of Cooperstown, Manitowoc County (Joel Trick)
||Flocks of migrating Double-crested
Cormorants overhead, on the west side of De Pere (Joel Trick).
White-throated Sparrows, Yellow-rumped Warblers, Dark-eyed
Juncos noted at Point au Sauble, Brown Co, the beginning of
the later migrants. Blue Jays migrating (Andy Paulios).
Very high (barely visible) flocks of migrating Canada
Geese, T. of Cooperstown, Manitowoc County (Joel Trick).
Cranes flying high over the UWGB campus (Bob Howe).
Flocks of Canada Geese feeding morning and
evening in fields near the East River, Allouez (Gary Fewless). We
have numerous geese that are full-year residents in this area, but
no large flocks of geese have been feeding in the Allouez fields
(Solidago canadensis) at about maximum color in local fields.
Very little color change in the tree leaves in the Green Bay area.
This is the latest I can recall for the beginning of Fall colors.
Usually by late August people are remarking how some Sumacs or Red
Maples are turning red, and other species usually begin to show
extensive yellowing by now.
A familiar "V" shaped flock of Canada
Geese were observed, heading south in Manitowoc Co in the evening
(Joel Trick). We do have resident geese in our area, but this may
represent the start of the annual southward migration.

The invasive species
Water Hyacinth (Eichhornia crassipes) was reported
for a pond on UWGB. This species normally only grows outside of
cultivation in the extreme southeastern U.S. Apparently someone
intentionally introduced this species to the pond on UWGB. All available
evidence indicates that Water Hyacinth will not tolerate a hard
freeze, so we expect that this problem species will be eliminated
in the next few months. The practice of indiscriminate release of
plants and animals has historically resulted in a great deal of
expense and disruption of natural and agricultural communities.
One outcome of this surprizing event is that I will
no longer scoff at unlikely reports of new plants or animals. (Gary
