American
Bittern
(Botauruslentiginosus)
Photographed at
Etobicoke Creek, Toronto, Canada Apr 2009
The American Bittern is a solitary, camouflaged coloured
heron that breeds in freshwater wetlands from northern Canada to the mid-United
States. It prefers tall sprouting vegetation, and frequents the vegetation
outer edges and shorelines. It relies on stealth more than pursuit to hunt,
waiting motionless for long periods to capture passing prey, mainly insects,
amphibians, crayfish, and small fish and mammals. It is most active during
fading light of dusk hours much like the Night Heron.
If it senses that it has been seen, the Bittern becomes
motionless, with its bill pointed upward, causing it to blend into the reeds as
seen in the photo.
This female builds the nest and the male guards it. Two or
three eggs get incubated by the female for 29 days, and the chicks leave after
6-7 weeks.
