Tracy Beerley, The McCausland Natural Areas Horticulturist
Colonies of red-winged blackbirds (Agelaius phoeniceus) arrived at the Morris Arboretum in early Spring. Within the Arboretum the birds are most common in the wetland and floodplain area.
The female spends three to six days building a nest constructed with grasses, sedges, mosses, and lined with mud. A clutch of eggs are incubated by the female and typically hatch in eleven to twelve days, the young birds are ready to fledge the nest two weeks after hatching.
