Linda Craiger followed up on the Glasgow radar roost ring and this is what she found! :o) bpb, Frankfort - - - - - - - - - - - - - - August 14, 2006: I think I may have found the source of the roost ring in Glasgow at Gorin Park. Last evening (Sunday), between 6:45 - 7:30, there were hundreds / thousands of Purple Martins with a few Starlings that flew into the top of trees & on electrical wires. At 7:35, a resident adjacent to the park shot what sounded like a shotgun into the trees by his house twice. Of course, many birds flushed, but landed again nearby. LINDA CRAIGER / Glasgow
