Seasonal changes in cock Pheasant calling behaviour in two Wanganui Pheasant populations | Notornis and Birds New Zealand

[摘要] Changes in cock Pheasant calling frequency during the breeding season were measured for two Wanganui Pheasant populations between 1986 and 1988 by recording counts at 2-week intervals during the period September to December. Calling intensity varied considerably between successive 2-week intervals. It reached a peak during mid-November but was much less by late December. To estimate variability between successive counts, call counts were recorded in six areas along the Wanganui-Manawatu coast between 6 and 11 November 1988. Within site variance averaged 25% of total variance between and within study sites.
