Guild (Birds Only) . Breeding-season guilds (or nonbreeding-season 

 guilds for winter residents and migrants) are indicated by a four-digit 

 code. The first digit indicates major food source or feeding habits: 1 

 indicates seeds and vegetation (73% of diet); 2, invertebrates; 3, 

 omnivorous (25-757o plant material); 4, vertebrates; 5, carrion. The 

 second digit indicates foraging stratum: 1 indicates bark or bole; 2, 

 ground, grass, and low shrubs; 3, tall shrubs or low forest canopy; 4, 

 mid-to-high forest canopy or tall trees; 5, air; 6, water. The third 

 digit indicates foraging strategy: 1 indicates bark or bole drilling; 2, 

 bark or bole gleaning; 3, ground and brush foraging; 4, tree foliage 

 foraging; 5, sallying; 6, raptorial; 7, dabbling or stalking in water; 8, 

 diving in water; 9, mud probing; 0, soaring or swooping. The fourth 

 digit indicates preferred nest site: 1 indicates cattails or bulrush; 2, 

 shore, marsh, or water; 3, cliffs, caves, rims, badlands, buildings; 4, 

 ground, grassland; 5, low shrub (less than 1 m or 3 ft); &, tall shrub (1 

 m - 3 m or 3 ft-10 ft); 7, tree branch (greater than 3 m or 10 ft); 8, 

 tree cavity; 9, underground burrow; 0, nonbreeding in study area. 



Status (Birds Only) . First letter denotes indicated status in the 

 study area: M indicates spring and fall migrant only; R, permanent 

 resident; S, summer resident; V, summer visitor (nonbreeding); W, winter 

 resident. For permanent and summer residents, evidence for breeding is 

 given in parentheses using a modification of Binford's (1973) categories 

 which are, in order of decreasing conclusiveness; PJ indicates prejuvenal 

 young observed; NY, nest with young; NE, nest with eggs; AN, active nest 

 completed, contents unknown; NC, active nest completed but empty; UC, 

 nest under construction; UN, active nest, condition unknown; AF, adult 

 carrying food; AC, adult carrying nest material; CO, copulation observed; 

 D, courtship display observed; TO, territoriality observed; RH, range, 

 habitat, an>d dates; SS, observed in area outside breeding season (for 

 sedentary or permanent resident species only). Only the most conclusive 

 evidence obtained during this study is listed in the table.

Ilonthly Occurrence . The letter "B" indicates observations made 

 during the baseline study period (DNRC 1978); the letter "T" indicates 

 observations made during other years. 



Table 3 summarizes the cumulative numbers of species observed in the 

 study areas during the baseline study and through the first, second, 

 third, and fourth monitoring periods. This table shows that two new 

 vertebrate species were added to the species list as a result of the 

 fourth year's monitoring; these are the bushy-tailed woodrat and house 

 mouse . 



Narrative Accounts for Selected Species 



Data in addition to that in Tables 1 and 2 were obtained for certain 

 key species, and are summarized in the following species accounts. 

 Information presented here, limited for the most part to nesting raptors, 

 upland game birds, and ungulates, primarily assesses changes that have 

 occurred in the Mine Study Area since the baseline study. Additional 

 data on all species are on file with DNRC.
