? =Unknown number of grouse for that category.
+ =Minimum count, other birds of same sex may have been present.
The relatively high counts at the Seneca leks in recent years are consistent with increased
counts at other sharp-tailed grouse leks throughout northwestern Colorado (Colorado Division of
Wildlife unpublished data, obtained from R. Hoffman). Although increased lek attendance by
males is an indication of increasing populations, the number of leks in an area is a better measure
of a population's status (Cannon and Knopf 1981). The establishment of three new leks at
Seneca II since 1995 may indicate a positive trend within the Seneca II region.
One male blue grouse (Dendragapus obscurus) was observed displaying along a road in
reclamation in NE'/ SE'/a Section 1, TSN, R87W on Z May 2003. Individuals (typically males)
have commonly been observed on the mine permit area during past spring surveys.
