Every first Saturday in September, bird enthusiasts and nature lovers gather to celebrate National Hummingbird Day. This day is dedicated to appreciating these tiny, agile birds and their role as a pollinator in our ecosystem. Hummingbirds are known for their incredible speed; they can flap their wings up to 80 times per second, allowing them to hover in place and even fly backward. Emily Dickinson aptly describes their swift movement: "A Route of Evanescence / With a revolving Wheel—." Their high metabolism requires them to eat constantly, so they spend their days flitting from flower to flower, sipping nectar and catching insects. Fun fact: these birds can remember every flower they"ve visited and how long it will take a flower to refill with nectar.
