Observations on the Nesting Habits of the Warbling Vireo (Vireo gilvus)
MetadataShow full item record
I studied two pairs of nesting Warbling Vireos (Vireo gilvus), one in the summer of 1966, the other in the summer of 1967 on land owned by the University of Michigan Biological Station near Pellston, Michigan. The pair in 1966 nested along the east branch of the Maple River in Emmet County. From 12 June to 18 July (26 days). I spent 49 1/2 hours watching these birds. I shall refer to this nest and pair as Nest 1 and Pair 1. The pair in 1967 nested on the campus of the Biological Station in Cheboygan County. From 12 June to 5 July (24 days) I watched this pair for a total of 54 1/2 hours. I will refer to these birds as Pair 2. This paper deals principally with my observations beginning with egg-laying and continuing through fledgling.With honors.
