The equivalent clearance of Britain's forest so long ago we have no sense at all of it, some of the great wetlands in 1600s, although it was not until 1800s that Ruff and Black Tern habitat in the Fens changed totally. Enclosures were profound change but much had long gone or been altered by 1700s.

Yes, 3-4 billion American Chestnuts dying after 1904 due to an introduced fungi, prairie and bison converted to crops and cattle, vast drainage, forest cleared, fire regimes suppressed so much of it in later 1800s.

Yes, you sense with the loss of these bird species the loss of vast dynamic ecosystems with natural perturbation of vegetation creating seral stages which provided habitat for these species, numerous other species will have been impacted by land conversion on such a vast scale, often so rapidly.

Audubon saw Ivory-billed Woodpecker regularly during his
travels down the Mississippi River near Arkansas Post in 1820. Audubon also painted the extinct Carolina Parakeet.

Sadly the prediction stated in this 1891 account of the Ivory-billed Woodpecker that vast tracts of undisturbed bottom wood forest will always support this species was overly optimistic, extinct after 1940s.

No Ivory-billed Woodpeckers seem to have been recorded in the sunk lands.

Gifford Pinchot visited this region in 1891, this account gives some sense of the region at that time.

You can read this with a free account, few ornithologists will have ventured into the sunk lands until exploitation created access, Bachman's Warbler had not been discovered in 1811.

Due to a Bluesky post I learned about the New Madrid earthquake in 1811/12 and the formation of the "Sunk Lands" where the St Francis river had flowed. I wondered if the conditions were suitable for Bachman's Warbler, they were.

Non-breeding range was restricted to Cuba.

It bred in disturbed swamp forest and may have been associated with Arundinaria gigantea cane brakes, males sang in the tree canopy, and made song flights, but nests were well hidden in undergrowth.

Murmuration is from Latin murmuratio meaning "the uttering of a low continuous noise", the sound is as much part of murmuration as the flying flocks of Starlings, which was very evident when I used to be amongst the Somerset Levels roost of a few million birds.

Nice that Harbour Porpoise has returned.
