"Roseate Spoonbill in Otoe County" from Nebraska Bird Review (June 1999) 67(2).
On 5 August 1997, W. Ross Silcock and I were birding the heron roost at the Waubonsie Wildlife Area in Fremont County, Iowa. We were hoping to see the Roseate Spoonbill I found there on 4 August (see Dinsmore 1998), and thought there might be a chance it would fly into Nebraska upon leaving the roost. At 5:53 a.m., the bird left the roost. It flew directly over us (in Iowa) and headed to the north with a Great Egret. We continued to watch the bird as it gained altitude and was joined by a second Great Egret. The birds were now flying northwest. After a couple minutes, all three birds turned suddenly to the west, and were soon over Nebraska. They then turned south and appeared to be following the bluffs along the Nebraska side of the Missouri River. At this time, they were barely visible through a 20x spotting scope. We watched them fly south over Nebraska City an eventually disappear to the south.
