Named American Bittern (Botaurus lentiginosus) by western bird aficionados and scientists, Alvin H. Wilcox, in his 1907 book “A Pioneer History of Becker County, Minnesota”, listed the local names for this then-common bird as Stake-driver, Shite-poke (or Shite-pump) or Thunderpump. More elegantly, the Ojibwe knew them as Mooskha’osi.
Difficult to see since they stick their heads up and remain motionless, like in the photo, and mimic dead cattail leaves, they are uncommon but widespread in North American marshes. The males have a loud, odd sound during breeding season that resembles a ‘crappy’ old-style levered water pump, blooping water out sounding like “ploomp ker ploomp”, or “booom pluuump”. Now they are fairly rare in Becker County -- What a difference a century of progress makes!
I took this picture May 25, 2017 in NW Minnesota. Check them out at this link, see more names for this bird (such as the Torcomón in Mexico) and listen to the song, call, or whatever the heck that noise is:
