Burnt

- for whatever reason this tree (in the vicinity of where I film the 'eagle's nest) seems burned from the ground up but still seems to be living - there are no signs of burning in the surrounding area.

Burned and burnt both work as the past tense and past participle of burn. Both are used throughout the English-speaking world, but usage conventions vary. American and Canadian writers use burned more often, and they use burnt mainly in adjectival phrases such as burnt out and burnt orange. Outside North America, the two forms are used interchangeably, and neither is significantly more common than the other.
Burned is the older form. Burnt came about during a period in the 16th through 18th centuries in which there was a trend toward replacing -ed endings with -t in words where -ed was no longer pronounced as a separate syllable.  Later, British writers continued to favor the newer -t forms for a handful of verbs, while North Americans went back to the more traditional -ed forms.
