I lived in New England for many years and never heard this word:

""That's the only unbanded chickadee for miles around," says Smith as the pair zips to
an apple tree. "Well, it's not quite true but almost. Listen. The female is calling
'feed me me.' She's growing eggs and he's busily foraging for her. Their nest must be
way out in the dingle," Smith speculates, using a New England colloquialism
for the tangled ravine that drops away behind a neat ranch house whose owners, she
assures a visitor, "know this weird person."

From UK:Where soils are wetter and more basic (calcareous), oak and ash often in
alley or dingle woods occur with alder, birch, wych elm, hazel and hawthorn. Ground flora
is often rich in ancient woodland indicator species. Examples occur particularly in Dudley
with dingle woods e.g. Cotwall End Dingle,
Wollescote and Hodgehole Dingles.
