Hummingbird Window Feeder
The construction and operation of this hummingbird feeder is incredibly simple. Attach the two base pieces together and connect three plastic flower-shaped feeding tubes (with or without stands), and you have a functioning feeder. Simply heat up some sugar-water as an analog to nectar, fill up a small water bottle, place it upside-down in the base, and attach the feeder to a window using the suction cups. Proper weather provided, hummingbirds and even butterflies will be flying right up to the window to drink the sweet treat. Simply swap out the sugar-water and rinse out the base every few days to keep the birds coming back for more.
