* The 1953 index is incomplete because Colorado, Utah, and Wyoming did 
not conduct call-count surveys until 1954. The percentage change from 
1953 to 1954 is based on comparable data only. 
**k Maine, New Hampshire, Rhode Island, and Vermont first established 
call-count routes in 1959. No estimate has been made of the square 
miles of dove habitat in these States.
