A good spot to catch a glimpse of the colorful American Redstart as it passes through Salter Grove would be the upland woods during spring migration from early to mid-May. Slowly scan the canopy between Upland Trail markers U3 and U4, or between markers P2 and P4 along the Pond Trail. It is an active warbler that flashes its colorful wing and tail patches to flush insect prey from the foliage.
The American Redstart is a sexually dimorphic warbler that breeds in the woodland of northern and eastern North America and winters in Central and northern South America. The adult male has bright orange patches that contrasts against its black body whereas the female has a more subtle brown plumage with yellow patches. Males in their first year have a plumage similar to that of females.
