How to read maps and interpret symbols 



Each species is listed by common and scientific name in taxonomic order. Order and 

 family names are inserted to aid in grouping the species. A common name is placed 

 in the top outside margin of each right hand page for the predominant group of 

 species found on that page. 



Information on the species' status is provided on the lines beneath some of the 

 names. Symbols and their definitions are explained below. Further information is 

 provided on page 4. See Appendix A (p.109) for a list of species. 



n= Number of documented records (for species with fewer than 20 verified 

 records). 



TES Species considered threatened, endangered, or sensitive. 



SI Additional information requested for these species. 



introduced - Not native to North America or a native North American species 

 transplanted to Montana. 



The distribution maps are shaped in the general outline of Montana. Each 

 rectangular block represents one latilong. Each symbol within the block represents the 

 highest documented status for the species in each latilong or quarter latilong. All of 

 the Third Edition data are presented in the center of the latilong block. The quarter 

 latilong data are presented in the corners of the latilong block and represent 

 observations submitted since 1985. The symbols used are as follows (see p. 11 3, 

 Appendix D, for complete definitions): 



B Direct evidence of breeding (nest or dependent young 



observed). 



b Indirect or circumstantial evidence of breeding. 



t Observed, no evidence of breeding. 



Absent or no observations submitted. 



The winter distribution of species is recorded between December 15 and February 

 15. Winter maps display data in latilong blocks only. However, post-Third Edition data 

 are recorded by QLL in the database. The symbols and their definitions are: 



W Overwintering. Regular sightings during the winter period. 



Overwintering not yet documented, but species observed at 

 least once between Dec. 15 and Feb. 15. 



Absent or no verified winter records submitted.
