This year continues to be better than average for Wilson’s phalaropes, yellow-headed blackbirds and now another Great Plains species, the Dickcissel. Large numbers of this sparrow-like grassland bird have been reported from weedy fields, pastures and other dry open areas around the state.
As we head into the unofficial start of summer, bird migration is winding down. Shorebirds are the most prominent remaining migrants, many of them headed for breeding areas on the far northern tundra. Species most commonly being seen include semipalmated, least, and white-rumped sandpipers, ruddy turnstone, sanderling, dunlin, and semipalmated plover. Unusual finds include whimbrel (especially along northern Lake Michigan), red-necked phalarope, and American avocet. Wilson’s phalaropes, a species whose core range lies in the Great Plains, have been far more numerous in the state this spring than any in recent memory.
Birdwatchers are delighting in a bounty of song and color as birds continue to return statewide. Baltimore and orchard orioles, scarlet tanagers, indigo buntings, rose-breasted grosbeaks, ruby-throated hummingbirds and other backyard favorites like house wrens, gray catbirds, American goldfinches and red-headed woodpeckers are showing well in most areas. Warblers are moving later than usual this year with large numbers still being seen in the southern tier of the state, only now including later species like Canada, bay-breasted, and Connecticut warbler.
The most anticipated time of year for birdwatchers has arrived! Right on schedule, May ushered in a wealth of neotropical migrants this past weekend, including Baltimore and orchard orioles, ruby-throated hummingbirds, rose-breasted grosbeaks, indigo buntings, scarlet tanagers and more. Not seeing any yet? Don’t despair as this is just the beginning of their return and has been limited mostly to the southern half of the state so far. Now is the time, though, even up north, to fill the seed feeders, prep the sugar water and offer orange halves and jelly.
Mild and dry weather allowed migration to advance steadily this week. The south continues to see excellent abundance and diversity of waterfowl, but with smaller numbers of swans and geese now. Shallow wetlands, ponds in open habitats and flooded fields have been hotspots, hosting various ducks, some greater white-fronted geese, good numbers of Bonaparte’s gulls, American white pelicans and growing numbers of shorebirds, including greater and lesser yellowlegs, pectoral sandpipers, Wilson’s snipes, and the first black-necked stilts. Tree swallows have become more prevalent, and the first purple martins and barn swallows have returned as well. Other water-associated species to look for now include ospreys, belted kingfishers and yellow-headed blackbirds.
Migration continues to ramp up across southern Wisconsin, bringing more birds inching farther north almost daily. The return of sandhill cranes, Canada geese, red-winged blackbirds and American robins have been especially welcome for many bird lovers from Eau Claire to Wausau to Green Bay and southward. Other new arrivals include the first American woodcocks, tree swallows, turkey vultures, eastern bluebirds, song sparrows and American white pelicans.
