Notes

Numerous waterfowl and gulls were seen around point. Including, Bufflehead, Green-Winged Teal, and Bonaparte's Gulls. Dark-Eyed Juncoes and Tree Sparrows were abundant in areas with a think shrub layer.

Large areas of exposed mudflats were exposed on the north beach today. Red-Tailed Hawks and Bald Eagles were hunting over the north beach. A partially eaten, female Lesser Scaup remained near point #1. One female Wood Duck remained with a flock of Mallards and Black Ducks near point #8. Also at point #8 a male Ring-Necked Pheasant was spotted scratching in the leaves for his morning meal. It's possible that pheasants will move to the point in the winter to utilize the cattails and shrubs for protection from the cold.
Greatest concentrations of Bonaparte's Gulls of the fall were spotted today. Snow Buntings, Killdeer, and Sanderlings were still present along the north beach. Sparrow and Blackbird numbers have decreased significantly. A lone Common Snipe was seen feeding in the lagoon near point #2.
Lesser Scaup numbers are down from a week ago, along with an almost complete absence of puddle ducks. Golden-Crowned Kinglets, Black-capped Chickadees, and Brown Creepers were active at numerous locations around the point. An adult Cooper's Hawk and a Rough-Legged Hawk were seen hunting over the point. A group of hunters, reported seeing a White-Winged Scoter while hunting off the point.
The main waterfowl migration is in full swing. Large flocks of Lesser Scaup and Canvasbacks were seen out from all sides of the point. The first Snow Buntings of the fall were seen along the beach. Fox Sparrows, Song Sparrows, Golden-Crowned Kinglets and American Robins are still locally abundant in the areas with a thick understory.
Lesser Scaup are very abundant in the lower bay, along with a few Redheads, Horned Grebes, and Common Loons. Rusty Blackbirds, Common Grackles and Red-Winged Blackbirds were abundant along the beach. A large flock Sanderlings and one Dunlin were seen feeding on the north beach. Very few gulls were seen along the point, could they be feeding in the fields?
Good numbers of Lesser Scaup are starting to show up in the bay. An Eastern Phoebe was still hawking insects near point #1. Golden-Crowned Kinglets, Yellow-Rumped Warblers, and White-Throated Sparrows were still present on the point. Sanderlings and Rusty Blackbirds were also seen feeding along the beaches.
Light rains made birding difficult. Yellow-Rumped Warblers were abundant. Winter Wrens and Red-Breasted Nuthatches were also seen with mixed passerine flocks. A large flock of Pectoral Sandpipers were feeding in the lagoon with some Killdeer. A small flock of Bonaparte's Gulls were seen flying north over the point near point #2.
The morning birding was highlighted by two Peregrine Falcons hunting over the point. Greater and Lesser Yellowlegs, Sora, and six different species of waterfowl were seen in the lagoon. Numerous passerines were found out on the point, including nine species of warblers, kinglets, Winter Wrens, and Hermit Thrushes. In the afternoon, a large warbler push dropped in on the point. Over 200 warblers were banded, mostly Blackpoll Warblers, and twice that number were released due to darkness and stress.
A calm, clear day made for good birding out on the point. An early flock of Lesser Scaup were seen out in Green Bay. Two Ruddy Turnstones were feeding with the gulls and waterfowl at point #6. Both Virginia and Sora Rails were heard calling in the lagoon. Numerous passerine species were counted, including a Philadelphia Vireo.
The most interesting sighting of the day was a chance to see a Peregrine Falcon chasing a Merlin out of the lagoon. Later the Peregrine was seen stooping on teal and shorebirds in the laggon and the Merlin was seen stooping on a Killdeer along the beach. Passerine migration is in full swing with eight warbler species and numerous Swainson's Thrushes.
The first Red-Breasted Nuthatches of the year were seen on the point. An immature Peregrine Falcon was seen hunting over the lagoon looking to make a Green-Winged Teal its morning meal. The passerine movement was slow overall. Blackburnian, Yellow-Rumped, Cape-May, and Northern Waterthrushes were identified. A juvenile Sharp-Shinned Hawk was later seen cruising the lagoon for an avian meal.
Large Flocks of Tree Swallows were hunting over the lagoon. Over 2000 Double-Crested Cormorants, were gathered in flocks in the bay around the point. Passerine diversity was low. An early Hermit Thrush was seen and a Canada Warbler was banded in net #3.
Sora Rails, Marsh Wrens, Greater Yellowlegs, Lesser Yellowlegs, and Solitary Sandpipers greeted us as we entered the lagoon. The lagoon is very dry due to low water levels, hopefully this will attract shorebirds as the season goes on. A group of four Common Mergansers were located off the north beach. Could they have been hatched on Green Bay? Banding was slow with only seven birds caught.
Migration is slow, with only a few migrating passerines showing up. Most of the summer residents are still around, including Eastern Kingbirds and Baltimore Orioles. Caspian Terns were seen loafing with a flock of Herring Gulls and a possible Western Sandpiper were present along the north beach.
Large flocks of Red-Winged Blackbirds are moving over the point to local agricultural fields. Passerine migration is slow, with most of the summer residents still present.
