Hwy 94 and H and Weldon Spring Conservation Area and Busch Wildlife Area
Started out at Hwy 94 and D in the Weldon Spring Conservation Area after receiving a tip as to where to find a Prairie Warbler. Played its call and in no time one came flying in. I then proceeded down Hwy 94 and turned west on the road at the south edge of the Weldon Spring Site Interpretive Center to look for a Henslow's Sparrow heard there a couple days ago. I walked the prairie north of the Hamburg Bike Trail. There were bulldozers making a lot of noise at the west end of the prairie so hearing them call was difficult. I finally heard a couple and walked into that area and played their call. All of a sudden I could hear one very loud, thought my iPhone was miss behavin', turned it off and still heard the very loud call. Looked to my left and 10-15 feet away there he was on a weed calling away. The next spot birded was Lost Valley Trail.
