net. This sagebrush-grassland site is located on the Crow Indian 

 Reservation. One bat, a male big brown bat ( Eptesicus fuscus) , 

 was captured. 



Bats were netted using one 5.5 m net set over a small flow of 

 water approximately 200 m upstream from the USPS Sage Creek work 

 station (T. VS., R. 26 E., Sec. 20, Carbon Co., MT; elevation: 

 1707 m) . The site was netted on five occasions: 9, 28, 29, 

 June; 9, 22 July. This site is a small drainage of open 

 sagebrush-grassland surrounded by Douglas-fir forest. In 

 addition to the bats listed below, a hoary bat ( Lasiurus 

 cinereus) was observed flying over the area on several occasions. 

 Table 7 includes one female long-legged myotis ( Myotis evotis ) 

 captured by hand as it fed on moths at a work station window.

The small-footed myotis ( Myotis ciliolabrum ) , was observed at the 

 ^twin hills' guzzler (T. 9 S., 26 E. , Sec. 7, Carbon Co., MT; 

 elevation: 1490 m) which is a BLM-constructed fiberglass wildlife 

 watering tank approximately 1,5 m X 1.5 m square. The site is in 

 sagebrush-grassland, and was netted on 29 June; 5, 2 6 July, using 

 two 9.5 m nets. Although few bats were captured (Table 8), many 

 bats were observed at this location, and were often seen avoiding 

 the net as they attempted to drink. There is no known water 

 within several kilometers of this location. Although no roosting 

 sites were apparent in the area, most bats were observed shortly 

 after sunset, indicating that the bats were arriving at the site 

 from a short distance away. No bats were observed beyond 1.5 

 hours after sunset.

The portion of Crooked Creek that was investigated (T. 9 S., R. 

 27 E., Sec. 2, Carbon Co., MT; elevation: 1550 m) is located on 

 USES land, and is accessible only by hiking either up or 

 downstream approximately 3 km. The outcrops of the surrounding 

 hillsides are generally too steep to climb into or out of the 

 stream bed in this area. While only one species of bat, Lasiurus 

 cinereus , was captured at this location, many bats were observed 

 flying overhead. Based upon their size, those bats were probably 

 Myotis spp. There is potential for bat roosts in this area due
