It is a birder named trail (NOT an officially named trail) that is part of the Weldon Spring Conservation Area in St. Charles co., adjacent to August A. Busch CA. See MDC map http://mdc.mo.gov/documents/area_brochures/7404map.pdf Directions to "Blue Grosbeak Trail" (BGT) From West St. Louis co. go west on Hwy 40/61 over the Daniel Boone Bridge (over MO River) into St. Charles co. Take the exit for Hwy 94/August A. Busch CA Turn left (west/south) onto Hwy 94 After the next stoplight within a few tenths of a mile, there will be a parking lot on the south side (left side) of Hwy 94 that is lined with LARGE ROCKS. ALERT: It can come up on you quickly and watch the traffic here (!!) so be aware. This is the parking lot for the Blue Grosbeak Trail. Believe on the MDC map the black square next to Fire Lake is this parking lot. The BG Trail starts at the large orange gate. (I do not know the official name of this hiking trail) If you pass the Howell Cemetery at the intersection of Hwy 94 and Hwy "D" (that goes to Busch CA) you have gone too far. Think the Northern Shrike was being seen in the general area at the top of the first hill in the field to the left along a multi-flora hedge. Hope this helps.
