Why would scientists want to monitor the migration habits of red-winged blackbirds in MA?

Blackbird and Oriole : Varieties of swamps, shrubs, swamps, and dry grasses; foraging in arable land and water. The species is most commonly found in freshwater marshes, but in wooded or bushy marshes, weed fields, hay fields, and salt marshes also have levels on the upper edge. Usually foraging in other open habitats, such as fields and tidal flats; outside the breeding season, flocks of chickens gather in farmlands, pastures and feedlots.

Among the birds we are most familiar with, the red wings seem to sing nasal sounds on every swamp and wetland from coast to coast. They are particularly bold, and a few often attack larger birds, such as eagles or crows, and they fly over their nesting areas. When singing, the male's red shoulder patches are hidden under the body feathers most of the time, which is very beautiful. Outside the nesting season, red wings sometimes live in large areas.

That's why. Hope it helps.
