Wisconsin Birding Report
Unseasonably warm temperatures have slowed the pace of bird migration across the state. Sparrows and juncos have begun to move into central Wisconsin and the red-breasted nuthatch "invasion" continues with large numbers of this species recorded in southern Wisconsin outside of its breeding range. A strong frontal passage earlier this week probably cleared the state of many of its remaining Neotropical migrant warblers and vireos and also included large numbers of white-throated sparrows, hermit thrushes, kinglets, bluebirds, yellow-rumped and palm warblers and other passerines. Waterfowl migration should pick up over the week with many blue-winged teal leaving and some puddle ducks and early diving ducks moving into marshes across the state. Rare birds reported this week included the continuing green-breasted mango in Beloit, cattle egrets at the Horicon NWR, Nelson's sharp-tailed sparrows in Madison, scoters from Wisconsin point and Chequamegon Bay, a Townsend's solitaire in Long Lake, and a black-backed woodpecker in Florence county. Birders at Concordia and along the Mississippi River have had good days for raptors during appropriate winds. As always, please report observations to eBird at
