As days wane and blossoms are no longer a source of nectar, nectar feeders become essential, particularly as a source of energy for migration.
Hummingbirds are one of the most popular birds that visit backyards, porches, and decks. They migrate long distances and depend on a source of energy to fuel their journey. Hummingbirds use up so much energy in flight that they could drain their body's energy stores within several minutes so a regular source of nectar is essential.
Hummers migrate at night and make a stopover at food sources, generally for a couple of days before resuming their trip.
