摘要:

Four pairs of Yellow Rails (Coturnicops noveboracensis) were radiotracked (1039 locations) in May-August 1980 at Seney National Wildlife Refuge, Michigan, to identify characteristics of breeding habitat and its use by Yellow Rails. Vegetation at nesting sites was dominated by Carex lasiocarpa (>90% of basal stems) in wet sedge meadows, which comprised nearly 90% of the 30-ha study area. Water depth in the meadows was 20-30 cm in spring, but standing water was absent by mid-July. Male activity areas overlapped and averaged 7.8 ha (range = 5.8-10.5) during preincubation and incubation; areas used by females averaged 1.2 ha (range = 1.0-1.7) during preincubation but declined to 0.3 ha during incubation.
