I would definitely agree that this is not Florida. Southern Central or Northern South America. It certainly looks quite alot like Pseustes sulphureus. At 39 seconds in there is a good profile of the snake showing the characteristic lateral compression along with the throat inflation which are trademark defensive displays of the giant bird snake. Also shows well the yellow interstitial skin where the snake gets its specific name sulphureus. As for the woodpecker it is certainly not a Piliated, but I'm inclined to believe it is not a Lineated either. The amount of red on the head and the fact that the white stripes converge to form a full V make it look more like a Crimson Crested Woodpecker Campephilus melanoleucus or one of the other Campephilus spp. However this is a snake forum so that's not really what's important
Regardless, it is not in Florida, not a yellow rat snake and instead most likely Pseustes sulphureus the giant bird snake.
Below is a photo of a large (8 foot) P. sulphureus I found in Ecuador.
