"Wanted to let you know about a rare bird sighting at Ijams. Yesterday morning I saw a red-necked grebe (and two horned grebes) at Forks of the River WMA [upstream from Ijams]. I came back in the evening, and the red-necked was near the boardwalk (the horned grebes were still in the Forks area)."
"Anyway, there's an irruption of water birds this year due to the extreme cold up north, where much of the Great Lakes froze over. Species have been on the move to find open water, including the red-necked grebe."
Details about this irruption can be found here: http://ebird.org/content/
