While birding this morning at the Lake Express on Milwaukee’s lakefront an American Kestrel, male was present. This species is commonly seen at this location or within a couple of blocks of the ferry. I watched it for 15 minutes and in that amount of time it flew to the ground 4 times and picked up fairly large insects and ate them. I would like to say the insect was a little bigger than a grasshopper and also had narrow clear wings. So not sure what the insect was. Bradford beach had one Juv. Great Black-backed Gull. The rest of the lakefront from Northpoint south to the Express I thought was very quiet. Images were taken on November 12, 2014.
