CAPE MAY WARBLER


Dendroica tigrina


Description:

This bird gets its name from Cape May, New Jersey, where the first specimen was collected in 1811. Its Latin name, tigrina, reflects the tiger striped appearance of the adult male. The Cape May Warbler primarily feeds on insects, but also consumes fruits and berries during the non-breeding season. Robert MacArthur, a pioneer of warbler ecology, demonstrated that this species (along with a few others) increases its clutch size when breeding during these outbreaks of the spruce budworm.
