In the Yucatan are some herons lesser than other members of the heron family of herons, night-herons, tiger-herons, egrets and bitterns? With the name of Least Bittern, is it a lesser heron? Hmmm. Only in size. As a foot long, football shaped bittern, this species wins as one of the smallest herons in the world! Sometimes the least can be the best.

Meanwhile its taller cousin, the American Bittern, also lives in the Yucatan as well as another bittern I’ve never observed, the Pinnated Bittern. All three live in the Yucatan all or part of the year and are well-camouflaged and well-adapted for their lives in marshes. Note the difficulty in spotting the American Bittern in its habitat. I would give it an award for its percussionist’s call. Don’t miss this extraordinary sound!

These shy, secretive herons skulk. Yep, a word I’ve not used often, but skulking benefits them to capture their meals of fish, frogs, crustaceans, insects, reptiles, and small mammals. (I wonder if they use skulk caps.)
Like typical herons the bitterns compress their necks into their bodies in flight. When hunting, their necks can extend as if attached to hydraulic lifts.

By the way, if you happen to check out bitterns at Cornell’s Lab of Ornithology website or bird field guides to North America, those resources state only two bitterns exist in North America, the Least Bittern and the American Bittern. Keep in mind their information doesn’t include Mexico or any Central American countries when North America is listed. It’s frustrating to me, and yes, I’m “em-bitterned” about it!
As far as the bitterns in Yucatan, I’ll now vote them as better’n those bird field guides of North America!
In PART 5 I’ll wrap up the heron family in the Yucatan with a couple of species.
