Do ,esants move to and from other coverts?     Dur1ng the last three 
winters  the State Conservation Departnwnt has tra ned and banded 349 
pheasants at t1je Fish Hatchery Prfug-, lr miles southeast of the 
Arboretum.  This is the fargst nearby winter covert. N rbor-tum band 
has apIared in these trappings, and only two Fish Hatcher7 bands have 
ac eared amon   the 521 birds tra--d and banded at the Arboretum tras during

the sae period. 
Anprently most pheasants return year after year to the ame winter 
quarters, and mary breed in th  saa   locality as that in wl ich they spend

the winter. 
How lor  does a, lhsant live? Of each hundred young Arbor tu 
pheasants surviving to reach their first winter, 26 survive to a second 
winter. 9 to a third, and 4 to a fourth. Xch generation It virtually 
extinguished by its fifth winter. 1his average survival series 
(100 - 26 - 9 - 4 - 0) is in effect an "actuarial t-bl'" for pheasants

whose "occupation" is to live on a refauge. The same sort of averages
are 
used by life insurance conanles to nredict the life-expectancy of policy-holders

in various human occupations. 
The life-expectancy of pheasants living on hunted ground Is doubtless 
shorter than for those on a refuge. 
Despite the fact that the Arboretum pheasants are not hunted except 
as they stray beyond its boindries, the life-expectancy of cocks is 
shorter than that of hens. The reason for this is unknown, but it accounts

for the preponderance of hens in the population (about 60 per cent).
