Tin whistle

It looks like recorder but cause made from metal have another sounds. Also very popular in folk/pagan bands.

Some information from Wikipedia:

The tin whistle is a simple six-holed woodwind instrument. It is an end blown fipple flute flageolet, putting it in the same category as the recorder, American Indian flute, and other woodwind instruments. A tin whistle player is called a tin whistler or whistler. The tin whistle is closely associated with Celtic music.

The whistle in its modern form stems from a wider family of fipple flutes that have been seen in many forms and cultures throughout the world. In Europe such instruments that have a long and distinguished history and take various forms; most widely known of these are the recorder, tin whistle, Flabiol, Txistu and tabor pipe.

The modern whistle is indigenous to the British Isles particularly England when factory-made "tin whistles" were produced by Robert Clarke from (1840–1882) in Manchester and later New Moston, England. downto 1900, they were also marketed as "Clarke London Flageolets" or "Clarke Flageolets". The whistle's fingering system is similar to that of the six hole, "simple system English flutes" ("simple" in comparison to Boehm system flutes). The six hole, diatonic system is also used on baroque flutes, and was of course well known before Robert Clarke began producing his tin whistles c. 1843.

While whistles have most often been produced in higher pitches, the "low" whistle is not unknown historically. The Museum of Fine Arts, Boston has in its collection an example of a 19th-century low whistle from the famous Galpin collection.
