Survival and reproduction of female Sichuan, ring-necked, and F1 hybrid pheasants

Article Abstract:

Sichuan pheasants were introduced in Michigan to increase falling pheasant numbers and to establish new populations. It was believed that the new arrivals would hybridize with existing ring-necked pheasants and could increase genetic diversity. A new study evaluates the reproductive success and survival of captive-reared female Sichaun pheasants, ring-necked and F1 hybrids released in southern Michigan. Results show little difference in dispersal differences among pheasant types, with higher survival and reproductive rates shown by Sichuan/ring-neck hybrids. However, releases of captive-reared pheasants to increase wild populations may be ineffective.

Evaluation of pheasant crowing rates as a population index

Article Abstract:

Call-counts of male ring-necked pheasants have commonly been used as a population index and it is assumed that the number of calls over a fixed time period corresponds to pheasant abundance. A new study measures the crowing rate of ring-necked pheasants during a fixed period to test the assumption that crowing rates are not linked to age, year, subspecies and weather variables. Results of the study support the hypothesis that crowing rates vary by sub-species, but wind speed, temperature and cloud cover are insignificant in explaining variations in crowing rates. Suggestions for improving crowing count surveys are included.

Movements and survival of molt migrant Canada geese from Southern Michigan

Article Abstract:

A study was conducted to determine the survival of migrating Canada geese when nesting areas were destroyed. Results showed that destruction of nests increased hunting mortality of geese besides other problems that need management.
