permittee The holder of a Federal migratory bird band- 
ing, marking, and salvage permit. 
postseason The 4¥2-month period of 15 January through 
31 May immediately after the close of most dove hunting 
seasons in the United States. Banding data from this period 
were omitted from this analysis. 
preseason The 3-month period of | June through 31 August 
before the opening of dove hunting seasons (1 September). 
Only preseason bandings were considered in this analysis. 
program BrowniE A computer program containing several 
age-dependent models to estimate survival and recovery 
rates for adult and immature mourning doves. 
program ESTIMATE A computer program containing several 
age-independent models to estimate survival and recovery 
rates for adult mourning doves only. 
recovery A banded bird killed or found dead and reported 
to the BBL. A recovery relates to a dead bird and is a 
terminal record. 
recovery rate This term refers to two different computa- 
tions: 
Its traditional definition was the proportion of banded 
birds that is subsequently shot or found dead and reported 
to the BBL. Recoveries + Bandings = Recovery Rate. 
Direct, indirect, and total recovery rates are computed 
in this manner. The computer derivation is the prob- 
ability (%) that a banded bird alive when a given cohort 
is banded will be shot during the next hunting season and 
reported to the BBL. This estimate is a composite rate 
that was computed by either program BROWNIE OT ESTI- 
MATE and should not be confused with the traditional 
estimate. 
recovery rate index Direct band recovery rate multiplied 
by 10,000.

relative recovery rate The probability of an individual in 
one cohort being recovered in comparison to an individual 
in another (e.g., immatures:adults), 
repeat (retrap) A banded bird recaptured and released alive 
within the same banding coordinates and within the same 
3-month period in which it was originally banded. Repeat 
records were omitted from this analysis. 
reporting rate The proportion of banded birds killed or 
found dead by hunters that is subsequently reported to the 
BBL. Recoveries + Hunter Encounters = Reporting Rate. 
return A banded bird that was recaptured and released 
alive within the same coordinates in which it was originally 
banded at least 90 days from the date of banding. Return 
records were omitted from this analysis. 
status A BBL computer code which describes the physical 
condition of a bird at the time of banding (e.g., normal, 
experimental, etc.). 
survival rate The probability (%) that a bird alive when 
a given cohort is banded will survive one calendar year to 
the time of next banding. 
tabulation A computer-produced data summary printed on 
paper. 
tiers States of the CMU and WMU were arbitrarily grouped 
into north-south oriented tiers to compare derivation of har- 
vest among the Southern Zone countries. 
weighting An adjustment to the number of bands recovered 
from specific harvest areas to compensate for differences 
in banding efforts among origination areas, as well as vary- 
ing sizes of areas and densities of breeding birds within 
them. Each recovery is placed in perspective to the number 
of birds it represents and allows computation of the rela- 
tive contribution that all breeding areas make to the har- 
vest of specific areas.
