The Office of New York State Parks & Historic Sites is reminding visitors to state parks to be on the lookout for the Ruby-throated hummingbird.

Ruby-throated hummingbirds will only be around for another month or so as they migrate southward. As nectar producing flowers and insect populations decline for the season the tiny birds will head south for Central America for the winter.

Weighing a mere 3-6 grams they will now start to gain an extra 25-40 percent of their body weight to prepare for this annual journey.

Ruby-throated hummingbirds fly alone and low just above tree tops or water so they can spot food sources and resting spots along the way. Migration can last 2-4 weeks, with a route that includes crossing 450 miles of open water at the Gulf of Mexico in a single flight without stopping.
