Wisconsin Statewide Birding Report 5.28.09
This should be the final week or so of spring bird migration through Wisconsin. Most of the warbler species are now on territory and remaining migrants tend to be the boreal species and females looking to arrive on territory. Common migrants now include Wilson's, Canada, blackpoll, bay-breasted and Tennessee warblers. Dickcissels are beginning to return to territories in southern Wisconsin grasslands and the mudflats are now home to many species of arctic nesting shorebirds. Rare birds reported in the last week include Swainson's hawks from Polk County, Nelson's sharp-tailed sparrows in Crex Meadows, red knots and whimbrels along lakes Superior and Michigan and laughing gulls in Milwaukee. As always, please report sightings to eBird Wisconsin (ebird.org/WI) to help track migrant bird populations.
