"ke-see"
The Brewer’s Blackbird is named after American ornithologist and naturalist Thomas Mayo Brewer.
Its range spread eastward from western Minnesota in the 20th century, taking advantage of human-produced changes in the landscape.
Within a colony most females choose the same kind of nest site. A colony may change its nest preference from year to year, building all nests in small bushes one year and in tall trees the next.
A group of brewer's blackbirds are collectively known as a "keg" of blackbirds.
