Wisconsin breeding birds

    Acadian flycatcher

    June is when most birds that call Wisconsin home nest, as this Acadian flycatcher has done, lay their eggs, and feed and teach their hatchlings to fly. Most Canada-bound birds have stopped over and flown on by. Organizers of the Wisconsin Breeding Bird Atlas are now calling for volunteers to help identify and count native birds to confirm if their populations are increasing, decreasing or staying the same.

    White-throated sparrow

    In Wisconsin, as elsewhere on Earth, the bulk of birds that breed in June and July are members of the order Passeriformes. They are considered true perching birds, with four toes -- three pointing forward and one backward, as seen with this white-throated sparrow here, allowing them to perch on vertical branches and posts.

    Western meadowlark

    Volunteers are documenting which species are found nesting in a particular block of land, and how that compares results from the same survey 20 years ago. What is the fate of the Western meadowlark, which anecdotal reports say have nosedived as grasslands continue to disappear? Photo credit: Ryan Brady

    Thrushes are medium-sized birds that include American robins. They typically are brown with spotted breasts but also include bluebirds. They are known for having some of the finest songs in the avian world. Populations of Swainson’s thrush, like this one here, may be declining and so its presence or absence is of particular interest to surveyors. Photo credit: Tom Prestby

    Vireos are plain-colored, sluggish birds that pick crawling insects from trees. The Philadelphia vireo was considered rare in Wisconsin 20 years ago when the first Atlas survey was conducted. What’s its fate today? Photo credit: Nick Anich

    Warblers are brightly colored songbirds, and more than 30 species were documented in Wisconsin 20 years ago. You likely won’t see them at your bird feeder, but listen and look for them in the forest as they are found throughout Wisconsin. The Cerulean is of a great interest because its populations have been dropping. Photo credit: Tom Prestby

    Grassland sparrows

    Wisconsin's grassland sparrows are declining, due to habitat loss here as elsewhere. Populations of the grasshopper sparrow, Henslow’s and Le Conte’s sparrows are expected to be down... Photo credit: Nick Anich

    Sedge wrens are sedge wrens, which often flee predators by running through the tall grass it prefers as habitat... Photo credit: Ryan Brady

    Did someone say finches? It’s been a very good year for pine siskin, one of those species that in some years may be present across portions of Wisconsin in large numbers, while in other years they’re hard to find. Photo credit: Ryan Brady

    Red Crossbills

    Red Crossbills – the males in this photo are red and the female yellow -- are an uncommon breeder in Wisconsin. Red crossbills are here in large numbers in some years, not so much in others. Their thick, curved bill with crossed tips helps them extract seeds from pinecones. Photo credit: Ryan Brady

    Purple Martins

    Feed me! These young purple martins will learn to catch insects on the fly and drink water on the fly. Their populations are declining in Wisconsin. Conservation efforts include installing more purple martin houses. Photo credit: Jack Bartholomai
