* From a base year, average doves heard calling per route for each State 
has been adjusted annually according to the percentage change from the 
preceding year in counts on comparable routes. The index, expressed 
in thousands, is the product of the adjusted average doves heard per 
route and the estimated area of dove habitat. 
** The area of dove habitat has not been estimated for Maine, New Hampshire, 
Rhode Island, Vermont, or Canadian Provinces. 
*** To date only Ontario and British Columbia have submitted comparable data 
for routes run in consecutive years.
