Mammals, such as flying squirrels, will occasionally discover a feeder and empty it at night. The only hummingbird we have in New Hampshire is the Ruby-throated hummingbird, although a rare vagrant species turns up every once in a while. The male ruby-throated has a red throat that will appear black if it is not in the sun. The female has a whitish-gray breast and both have a greenish back. The young resemble the female during their first year.
Hummingbirds migrate south at summer's end.
Adults will usually migrate first, often as early as the beginning of August. The young usually stay longer and are gone by the end of September. Research has shown that hummingbirds will migrate regardless of whether there is food present, so you can leave your feeder up until the weather turns colder and the hummingbirds are gone. We hope you enjoy watching these wonderful birds. All rights reserved.
