Fig. 18. Relative frequencies of recovery in the Western Manage- 
ment Unit for adult mourning doves banded in designated areas 
of the Central Management Unit. Example: An individual dove 
banded in Montana, Wyoming, or Colorado is 19 times more 
likely to be recovered in the WMU than a dove banded in any 
of the remaining CMU States (19/1 = 19). 
Dakota, and South Texas (11); and the remaining CMU 
States (1). 
An immature dove banded in Missouri was 2 times more 
likely to be recovered in the EMU than an immature dove 
banded in Minnesota, lowa, and Arkansas; 8 times more 
likely than an immature dove banded in North Dakota, 
South Dakota, and South Texas; and 91 times more likely 
than an immature dove banded in the remaining CMU 
States (Montana, Wyoming, Nebraska, Kansas, Colorado, 
New Mexico, Oklahoma, and North Texas). 
An immature dove banded in Minnesota, Iowa, and 
Arkansas was 4 times more likely to be recovered in the 
EMU than an immature dove banded in North Dakota, 
South Dakota, and South Texas; and 43 times more likely 
than an immature dove banded in Montana, Wyoming, 
Nebraska, Kansas, Colorado, New Mexico, Oklahoma, and 
North Texas. 
An immature dove banded in North Dakota, South 
Dakota, and South Texas was 11 times more likely to be 
recovered in the EMU than an immature dove banded in 
Montana, Wyoming, Nebraska, Kansas, Colorado, New 
Mexico, Oklahoma, and North Texas. 
Tendency for adult doves to migrate to the Western 
Management Unit. — The tests for independence of doves 
banded as adults in the CMU and recovered in the WMU 
indicate two groups of banding locations with different re- 
covery patterns in the WMU (Fig. 18). For the northwest-

ment Unit for immature mourning doves banded in designated 
areas of the Central Management Unit. Example: An individual 
dove banded in Montana, Wyoming, or Colorado is five times 
more likely to be recovered in the WMU than a dove banded 
in North Dakota, South Dakota, or Minnesota (102/21 = 4.9). 
ern tier of CMU States (Montana, Wyoming, and Colo- 
rado), the combined recovery rate index was 4.28; for the 
remaining CMU States, it was 0.23. Thus, an adult dove 
banded in Montana, Wyoming, and Colorado was 19 times 
more likely to be recovered in the WMU than an adult dove 
banded in the remaining CMU States. 
Tendency for immature doves to migrate to the Western 
Management Unit. —The CMU States (Montana, Wyo- 
ming, and Colorado) with the highest probability for doves 
banded as immatures to be recovered in the WMU were 
the same as for adults (Fig. 19). This northwestern tier of 
CMU States had a combined recovery rate index of 9.20 
(CRF = 102). The remaining CMU States were divided 
into two groups. The northern States (North Dakota, 
Minnesota, and South Dakota) had a combined recovery 
rate index of 1.87 (CRF = 21), and the remaining area 
(Nebraska, Iowa, Missouri, Kansas, New Mexico, Okla- 
homa, Arkansas, North Texas, and South Texas) had an 
index of 0.09 (CRF = 1). Thus, an immature dove banded 
in Montana, Wyoming, and Colorado was 5 times more 
likely to be recovered in the WMU than an immature dove 
banded in North Dakota, Minnesota, and South Dakota, 
and 102 times more likely than an immature dove banded 
in the remaining CMU States. An immature dove banded 
in North Dakota, Minnesota, and South Dakota was 21 
times more likely to be recovered in the WMU than an 
immature dove banded in Nebraska, Iowa, Missouri,
