An unusual red-pigmented Baltimore oriole showed up during a Sturgeon Bay Christmas count many years ago. Submitted.

This is the time of year when we begin organizing the annual Christmas bird counts. The Sturgeon Bay count will take place all day Saturday, Dec. 18, and the Southern Door count will follow on Sunday, Dec. 19. Both have been run since 1996.
A season with mild temperatures and little snow cover makes it easy for birds to find food, so they consume many weed seeds and insect eggs from plants and trees. These conditions frustrate people doing feeder counts because few birds find it necessary to take the handouts, and we get complaints that there were “no birds” at the feeders.
A lack of snow on the ground also makes it more challenging for the teams of birders who search open fields and roadsides because the birds often blend in with the drab ground and are hard to see. We also don’t like strong winds on count days because wind makes it difficult to hear birds, and many may seek shelter from the gusts by hiding in shrubs and tall grasses.
A ground cover of a few inches of snow really helps field counters to see birds as they swoop over the countryside in search of food and shelter, and deep snow is ideal for getting more birds to visit feeders because much of their natural food is hidden.
A large number of species nest in Door County and remain here all winter, including the Canada goose, mute swan, mallard, American black duck, common goldeneye, common merganser, red-breasted merganser, ring-necked pheasant, ruffed grouse, wild turkey, rock pigeon, mourning dove, ring-billed gull, herring gull, sharp-shinned hawk, Cooper’s hawk, bald eagle, great horned owl, barred owl, red-bellied woodpecker, downy woodpecker, hairy woodpecker, pileated woodpecker, blue jay, American crow, common raven, black-capped chickadee, red-breasted nuthatch, white-breasted nuthatch, golden-crowned kinglet, European starling, house sparrow, house finch, purple finch, American goldfinch and northern cardinal.
Mild winters with very little snow cover and open water in creeks and bays encourage more nesters to stay here. Those include the hooded merganser, great blue heron, northern harrier, red-tailed hawk, American kestrel, merlin, horned lark, brown creeper, American robin, cedar waxwing and eastern meadowlark.
Every autumn, Wisconsin birders can get the forecast of finches and other far-northern breeders that are migrating down to our state. When seed supplies on trees in Canada are scarce, the birds fly south to seek enough food to sustain them through the cold months.
Wintering birds from the north to look for in fields, along shores or at feeders are the redhead duck, greater scaup, long-tailed duck, bufflehead, some scoters, rough-legged hawk, snowy owl, northern shrike, Bohemian waxwing, evening grosbeak, pine grosbeak, common redpoll, white-winged crossbill, pine siskin, snow bunting and American tree sparrow.
A bird that breeds down south is the Carolina wren, but on many occasions, we have seen one in Door County and, strangely, mostly during the winter while visiting suet feeders. This past year, there may have been one living in our county all summer. Two other species that are uncommon but have been seen here are the Townsend’s solitaire and varied thrush. Both breed in the far western mountains.
We are fortunate to have two brothers who drive to Door County from neighboring states to help with both of the area bird counts. They work hard at searching out and listening for unusual birds, and they start before dawn to find owls calling. They often hear the eastern screech owl, which may be more common here than we think. It’s a small owl with a distinctive call – a call that may alert a nearby great horned owl, which is its predator.
During mild winters, these two excellent birders have found the common loon, eastern bluebird, northern flicker, winter wren, hermit thrush, swamp sparrow and white-throated sparrow. A yellow-rumped warbler has been found during a few counts.
We encourage more people to participate in these counts by contacting the coordinator to learn how they can help. The data that participants collect goes to the National Audubon Society and is available to researchers who study birds, habitats and migration patterns. The future of wild birds is being affected by global climate change, and we may be able to help mitigate these conditions if we learn more about winter populations in various parts of the country.
