Little Belts that may be prey items for boreal owls. 



As Mullen (1990) pointed out, short term surveys such as this 

 do not take into account the yearly variation in boreal owl calling 

 rates and any management directed solely by this one year of study 

 may be harmful. Additional survey years may yield owl observations 

 in areas that did not result in boreal observations this year. At 

 least 4 years of surveys should be conducted to effectively 

 determine boreal owl distribution in the area (Mullen 1989) . Repeat 

 surveys and additional surveys should be conducted, extending 

 through April to better cover the study area. Emphasis should be 

 placed on locating nest sites to gain a better idea of breeding 

 habitat in the Little Belts.
