	avian information	2005-08-17	2005-11-11		Marshall		8/17-18, 10/22, 11/6-11 Marshall (first fall record) Above-average yet unexpectedly low numbers following last year's record-high irruption (*The Loon* 77:194–208).

Most unusual was one well-described near Trail (where Great Grays were found last spring, but not during the summer) 9/2 Polk MG fide JMJ.
	avian information	2006-02-26	2006-03-12		Norman		2/26-3/12 Norman (first county record) Excluding potential breeding birds, PHS compiled a total of 96 individuals in 16 counties mid-August 2005 through March 2006, 69 of which were first found during the winter season. Following last year's record smashing irruption (*The Loon* 77:194–208), this “echo” effect, i.e., a smaller irruption immediately following a major one, was much smaller than anticipated. For example, the daily high count by a single party last winter was a dumbfounding 256 Great Grays; however, the highest count this winter was just 6 individuals 12/29 Lake of the Woods fide JMJ. This winter's birds essentially stayed within their normal winter range and habitat; the only exception was 2/26–3/12 Norman (near Gary) ph. PBB.
