Mammals of Carolina Bays 19 



mature forest types, as well as over water, in all study areas. Single 

 specimens were collected from the sand rim at Singletary Lake and Sal- 

 ters Lake, Bladen County; the specimen from Salters Lake was col- 

 lected while it was foraging on 20 February 1984. Records from Dare 

 and Hoke counties indicate that this bat is also common above both 

 xeric and palustrine communities, and we saw individuals feeding over 

 study sites in Pender County. We have several times observed Red Bats 

 migrating by day (April) through Pond Pine-shrub bogs. 



Lasiurus seminolus (Rhoads), Seminole Bat. We have a specimen of 

 this species (NCSM 3701) collected over the sand rim adjacent to a 

 Carolina bay in Hoke County. Bill Adams, U.S. Army Corps of Engi- 

 neers, has collected many of these bats over large bodies of water in 

 southeastern North Carolina (NCSM). We therefore find it likely that 

 Seminole Bats occur regularly over many bay lakes. 



Lasiurus cinereus cinereus (Palisot de Beauvois), Hoary Bat. Migrants 

 and winter residents of this species were seen and collected adjacent to 

 savannas, pine-shrub bogs, bay forests, and similar areas. We think they 

 were seeking cleared, open areas for foraging and were not found in 

 pocosins per se. We have also observed the Hoary Bat over large rivers 

 in the southeast and suspect that it regularly forages over bay lakes. The 

 thick vegetation of white cedar and evergreen bay forests provides 

 potential roost sites, but roosting in these habitats has not been con- 

 firmed. We saw a Hoary Bat flushed from a hollow stump during a 

 controlled winter burn of a stream-head forest and sand ridge at Wey- 

 mouth Woods State Park, Moore County, and several were seen in the 

 spring of 1984 foraging over a borrow pit pond in a Brunswick County 

 savanna. Our documentation indicates that dates of occurrence range 

 from 28 September to 17 April. 



Nycticeius humeralis humeralis (Rafinesque), Evening Bat. The Even- 

 ing Bat was commonly seen flying at canopy height in savannas, and 

 along the edges of mature bay forests and swamps adjacent to fields. We 

 were told of a local pest exterminator who gassed and removed "bucket- 

 fulls" of these bats from a boathouse on White Lake, Bladen County. In 

 July 1983 we collected one specimen of many seen flying over a savan- 

 na in Brunswick County. The stomach of this bat, collected during late 

 dusk, was already filled with fragments of recently consumed insects. 



Plecotus rafinesquii macrotis (LeConte), Rafinesque's Big-eared Bat. 

 We have numerous records of this rare bat from the Bladen Lakes area, 

 Bladen County, although only four of them were directly associated 

 with bays. One individual was reported by a local property owner in a 

 hollow Black Gum cut from the edge of White Lake, another was seen
