MBTA Organizations Abbreviation

Massachusetts Bay Transportation Authority

If you're from New England, "MBTA" most likely refers to the Massachusetts Bay Transportation Authority, which operates Metro Boston's bus, rail, and trolley systems. The term has also been used for more than a century to refer to the Migratory Bird Treaty Act of 1918, which was enacted in conjunction with a treaty with Canada to preserve egrets and other birds whose plumage was plucked to embellish ladies' hats. The latter MBTA has been enlarged to protect all types of migrants, while commuters may now take the old MBTA all the way to Braintree.
