hummingbird \hummingbird\, humming bird \humming bird\n. (Zo["o]l.), any bird of the family Trochilid[ae], of which over one hundred genera are known, including about four hundred species. They are found only in America and are most abundant in the tropics. They are mostly of very small size with long slender bills adapted to sucking nectar from flowers, and are noted for the very brilliant iridescent colors of their plumage and their peculiar habit of hovering about flowers while vibrating their wings very rapidly with a humming noise; the wings are specialized for hovering flight, but they can also dart forward and fly quite rapidly. They feed both upon the nectar of flowers and upon small insects. The common humming bird or ruby-throat of the Eastern United States is Trochilus colubris. Several other species are found in the Western United States. See Calliope, and Ruby-throat.

Humming Bird is an album recorded in 1970 by Paul Gonsalves.
The Humming Bird was a named train of the Louisville and Nashville Railroad (L&N). The train, inaugurated in 1947, originally ran from Cincinnati, Ohio, to New Orleans, Louisiana, via Louisville, Nashville, Birmingham, Montgomery and Mobile and later via a connection at Bowling Green, Kentucky, to Memphis, Tennessee. A connection to Chicago was provided by the Chicago and Eastern Illinois Railroad.
In the mid-1950s, Train 5 departed Louisville at 10:05 pm for New Orleans. Train 6 was the northbound number.
The original equipment was part of a 28-car order of four train sets of lightweight stainless steel cars built in 1946 by ACF. Fourteen cars were assigned to the Humming Bird and fourteen to the Georgian. Many of those cars were removed from service in the late 1960s due to severe corrosion problems.
The L&N Railroad served the old Union Station in Memphis, until its closure on April 1, 1964. The railroad then used Central Station. Both L&N and Southern Railway were forced to reopen part of Union Station on December 1, 1966, and use it until March 30, 1968.
The Humming Bird was canceled on January 9, 1969. At that time, the L&N Railroad earned some unwanted publicity when it terminated the final run of the train en route southbound at Birmingham when a federal judge lifted the order keeping the train running after the Interstate Commerce Commission approved its permanent discontinuance. The passengers were then bused to their destinations.
The train inspired the song " Hummingbird" by country artist Ricky Skaggs and was mentioned in the song " Southern Rains" by country artist Mel Tillis.

The humming bird's wings, therefore, must move to and fro more than thirty-two beats in a second, and it is simply in consequence of the fact that his body and wings are so small that the rapidity of the motion of his wings comes within the limit above referred to, and sound is produced.
