On 18 April 1987 Bob Reid, Fred Alsop, and Jerome (Buddy) Cooper, discovered a ásizeable” colony of CliffS wallows (Petrochelidon pyrrhonota), under an Iá20 overpass over a railroad near the river at Riverside in St. Clair County. Thirty.five nests were counted on 7 May 1988. Bob feels that the colony is probably in its second or third year of occupancy. A colony on the Upper Coosa at Weiss Lake was established in the midá 70’s (see map, Figure 3). The birds reached Mobile in ’82, and the first nest in coastal Mississippi was noted in ’86. Other colonies on the edge of the Piedmont in North Carolina and South Carolina were discovered in ’85 and ’86.
