December, 2011 will be remembered by us birders as an incredibly good month for the bird numbers and variety that it produced at White Memorial and Bantam Lake. We can thank unusually mild weather for much of the month for this. Though there were a few cold nights, and fewer cold days, Bantam Lake never froze-over more than 50% of its surface area. Little Pond was at least 50% open for the first 3 weeks of the month, and Cemetery Pond had open water at various times this month. Even our marshes and swamps remained at least partially ice-free for much of the month. Amazingly, there was no snow cover at any time this month. The 20" of snow which fell last October 29 and 30 had long-since melted. These favorable conditions, coupled with an abundance of wild food of all types, made life relatively easy for birds around here. It also allowed many birds to linger and not migrate farther south. Waterbirds, especially, benefited from the mild conditions and resultant open water. An abundance of fish in Bantam Lake also helped attract and keep a good variety and number of these birds. Imagine how many fish must have been consumed there on 12/31 when the Lake hosted 1,000 Common Mergansers, 87 Hooded Mergansers, a Red-breasted Merganser, a Pied-billed Grebe, a Great Cormorant, 7 Bald Eagles, and 2 Belted Kingfishers. The Great Cormorant is a rare species in this part of CT., having been found on Bantam Lake only 4 times in the past. It stayed around for almost 2 weeks, so it must have found the fishing to be good. That was probably also true for the Pied-billed Grebe, which was found here all month. They are common in October and November, but seldom stay beyond that time. Its much rarer cousin, the Red-necked Grebe, has occasionally lingered into the first week of December at the Lake, but never as late as 12/20, as it did this year. Consequently, it was a first for the Christmas Bird Count. Other "goodies" found on the Lake this month included as many as 10 Gadwalls, American Wigeons on a few occasions, Northern Shovelers all month, 2 Northern Pintails almost all month, a Green-winged Teal 1 day, as many as 9 Lesser Scaup during the second half of the month, 2 White-winged Scoters and a Long-tailed Duck 1 day, single Red-throated and Common Loons each 1 day, and a Horned Grebe during the first week of the month. The Gadwalls and N. Pintails were also seen at Little and Cemetery Ponds when they were ice-free. Landbirds of note seen this month included a Red-shouldered Hawk at the Morris Town Beach, an Eastern Screech-Owl at Little Pond, a Yellow-bellied Sapsucker around the Museum Area, Common Ravens, Red-breasted Nuthatches, Brown Creepers, a Carolina Wren at the Campground Store, a Winter Wren at Pike Marsh, a Hermit Thrush and Yellow-rumped Warbler at Little Pond , a Fox Sparrow at Van Winkle Rd., Swamp Sparrows, 86 Rusty Blackbirds at Little Pond on the 1st, and 13 Purple Finches at the Museum Feeders on the 18th. While most of the birds not noted at an exact locality in the last run-on sentence were seen around the Museum Area, some were also regularly seen at Pine Island. In general, spots around Bantam Lake, the Museum Area, and Little Pond were the most productive for birds at White Memorial in December.

The relatively mild weather that has blessed Connecticut for much of the past 6 weeks should have been conducive to let late migrant birds linger around here for longer than they usually would. This is especially likely when there is an abundance of wild food, as there is this year. However, unlike the waterbirds discussed in my last post, there don't seem to be all that many migrant landbirds lingering around here. They do take more effort to find than waterbirds, but we have tried to look for them on a few occasions this month. This is not to say that we haven't had some success. Yesterday, I was greeted by a Yellow-bellied Sapsucker when I went up onto the Museum's deck to fill the feeders. When they get hungry enough they will visit suet feeders. On the 7th, Mike Doyle had a Belted Kingfisher at Bantam Lake's Pt. Folly. They will occasionally stay through the winter if there is enough open water and an adequate supply of small fish to eat. On the 5th, Buzz Devine counted 86 Rusty Blackbirds in a flock along the north side of the Little Pond Boardwalk. Four days later, I saw 2 at Cemetery Pond. They are quite nomadic, and probably have gone farther south by now, but every year we find a few Rusties around here during the winter. Some Red-winged Blackbirds also spend the winter here. Our most recent report of them was from the Museum's feeders on the 10th. Though I haven't seen a Winter Wren or Fox Sparrow on White Memorial property since 11/25, that doesn't mean that 1 or 2 aren't around here somewhere. I have seen a Fox Sparrow elsewhere in Litchfield in the past week. It is a little odd that we haven't seen any big flocks of American Robins around here since 11/25, especially given the continued abundance of Winterberry Holly berries. They may be around; just not in places that we haven't visited lately. All that will change this coming Sunday, 12/18, when we plan to cover White Memorial's property and Bantam Lake as thoroughly as possible for the Litchfield Hills Christmas Bird Count. If you would like to help, please email me at dave@whitememorialcc.org. I still need people who can work independently censusing birds along some of our outlying trails, like the Cathedral Complex and Trail Rider's Jump.

Major Early Snowstorm and its Aftermath

Connecticut was pounded by a record-breaking early Nor'easter snowstorm from around 1 p.m. on Saturday, 10/29/2011, through sunrise on Sunday, 10/30/2011. It dropped 20" of snow on White Memorial and was accompanied by high winds for about 8 hours. This spelled disaster for many trees, shrubs, and other plants which were either flattened by the heavy, wet snow, or broke under its weight. Power was knocked out to the Museum Area for 9 days. Much of the tree damage involved broken limbs or sections of trunk rather than entire trees being blown over as happened during the tropical storms in August and September. Still, damage is extensive, and it will take quite a while to get all of our trails cleared despite the Herculean efforts of our great maintenance crew. A major savior to our wildlife (especially the birds) through all of this mess has been the super abundance of berries, nuts, and seeds. Though it was rendered unavailable for a while after the snowstorm, rapid melting of the snow exposed much of these foods within 12 hours. Therefore, I doubt that much, if any, starvation occurred among our wildlife. One exception would be totally insectivorous birds, but virtually all of them had already migrated south before this storm. One species just beginning to migrate south through here now is the Fox Sparrow. Bird feeders can greatly help these birds through foul weather, and that proved to be the case for the feeders behind the museum. In addition to hosting a ton of White-throated Sparrows, Dark-eyed Juncos, and other common birds after the snowstorm, they also fed 3 Fox Sparrows for a week. Since then we've seen this species feeding on weed seeds along the Little Pond Trail and at the Butterfly Garden. Some people expressed concern for American Robins, Eastern Bluebirds, and Cedar Waxwings after the storm, but they are doing just fine chowing down on an abundance of Winterberry Holly and Pokeweed berries. Waterbirds seemed to be unphased by the storm since Bantam Lake and most of our ponds (except Cemetery) remained ice free. Bald Eagles and other raptors seemed to carry-on as usual. I even saw 2 different Bald Eagles fly low over the museum on Sunday, 10/30, while I was shoveling snow off the deck. So, while this unprecedented snowstorm completely disrupted the lives of us humans and did quite a bit of damage to vegetation, it probably didn't do much harm to our wildlife.

Peregrine Falcons over WMF Hawk Watch, 9/30/11

The weather finally improved enough on Friday, 9/30/11, to conduct a hawk watch around the Museum Area between 11:00 a.m. and 3 p.m. Since the winds were out of the southeast, south, and southwest at a sustained 20 m.p.h., conditions were not really good for hawk migration, but 30 members of this group flew over our site, anyway. I wouldn't have bothered to engage in hawk watching/counting this day if it hadn't started with a gorgeous adult Peregrine Falcon flying low over us. It went from north to south without showing any difficulty in dealing with the headwind. Soon after that the first of 8 high-flying migrant Red-tailed Hawks went over. This species doesn't usually migrate until later in October or November, but these birds had to be migrants because of their altitude and their direct flight from northeast to southwest. The rest of this day's migrant raptors consisted of 4 immature Bald Eagles, 6 Ospreys, 5 Sharp-shinned Hawks, 4 Cooper's Hawks, 1 late Broad-winged Hawk, and an immature Peregrine Falcon. We, and the hawks, quit when the sky became overcast. So far this fall's hawk watching hasn't been particularly good at White Memorial because the weather has been unfavorable, and quite often downright awful, for most of the month of September. We've only been able to put in 4 days of effort, which has yielded a grand total of 412 hawks. This breaks down to 354 Broad-winged Hawks, 14 Sharp-shinned Hawks, 9 Bald Eagles, 8 Ospreys, 8 Cooper's Hawks, 8 Red-tailed Hawks, 4 Red-shouldered Hawks, 4 Black Vultures, 2 Peregrine Falcons, and 1 N. Harrier. It is amazing that we haven't seen any American Kestrels, yet. We hope to have at least one more day of good hawk watching conditions before their migration season ends. Last year, we counted a total of 905 hawks passing over our site on 15 favorable days, so we don't expect to come anywhere close to that figure, but it would be nice to end this year with a total around 450. If the weather forecasts are correct, we might be in for more movement later this week.

The White Memorial hawk watch started its 2011 season on September 16th with a good showing of birds. The weather for much of the month prior to this was too lousy for hawk migration to occur. By contrast, the weather on the 16th was sunny, very cool, and with a steady 20 - 30 m.p.h. wind from the northwest. These conditions were optimal for hawk migration along the coast, as many birds were blown that far. I saw reports from Lighthouse Pt. in New Haven of 3,000 hawks and from Greenwich Audubon Center of 6,000 hawks that day. Inland sites, like White Memorial did o.k., but the results were not nearly as impressive as those from coastal sites. We counted a total of 259 hawks passing over the Museum Area between 10:15 a.m. and 5:15 p.m. The vast majority of these (255) were Broad-winged Hawks. The biggest kettle (or group) of Broad-wings consisted of 40 birds circling around overhead at one time. We also saw 1 Osprey, 2 Bald Eagles, and 1 Sharp-shinned Hawk. The next day, 9/17, was our "official" hawk watch day for the public. About 20 people attended at various times between 10:15 a.m. and 5:15 p.m. and were rewarded with a total of 107 hawks passing overhead. Of these, 93 were Broad-winged Hawks, including 50 in one kettle. We also saw 2 Black Vultures, 1 Osprey, 3 Bald Eagles, 3 Sharp-shinned Hawks, 2 Cooper's Hawks, and 3 Red-shouldered Hawks. No one manned our hawk watch site on Sunday, 9/18, but judging from observations from other places, we didn't miss much. Winds were coming from out of the south, and hawks weren't moving. The next day, 9/19, the winds shifted around to the west, and a few hawks started moving in the afternoon. Between 2 and 5:15 p.m. we counted a total of 16 hawks passing over the Museum Area. These consisted of 2 Black Vultures, 1 Northern Harrier, 5 Sharp-shinned Hawks, 2 Cooper's Hawks, 1 Red-shouldered Hawk, and 5 Broad-winged Hawks. The weather since this day has been too lousy for hawk migration to occur.
