We’re in Maryland, and can usually expect to see them until about the middle of September, but sometimes we have them later (probably stopping off in migration from up North.)
They never get boring.
The absolute latest I’ve seen a hummingbird is the third week of October here. That was probably about 5 years ago. My mom loved “hummies” so those were some of the first bird feeders I ever bought as an adult. They are adorable little creatures.
