UW Arboretum Odonata Monitoring Project - Gardner Area UW Arboretum East Entrance & Gardner Marsh. Includes channelized Wingra Creek either direction from the Arboretum Drive bridge over the creek and the Gardner Marsh trails/boardwalks. On Wingra Creek, saw 2 House Sparrows with teneral damselflies in their beaks and many other House Sparrows foraging on (including hovering over) the lily pads. See https://ebird.org/checklist/S362915284 for photos of this. Gardner Marsh trails/boardwalks (nothing on the water lilies in the open water here): 940-1017am, 65-67F, calm, sunny. Wingra Creek (lots of unidentified pastel blue thorax damselflies on the water lilies here, suspect most were Slender Bluet, and Skimming Bluet as well): 1019-1148am, 68-71F, sunny to partly cloudy, light breeze (6-7 mph, gusts to 9-10 mph)
