Using this bird feeder is easy. First, lift off the raised shingle roof to fill it with either thistle feed or mixed seeds, depending on which way you've set the 4 dual - purpose hinged ports. When it's time for cleaning, just remove the seed base, which also doubles as a perch. As for maintenance, keep it in a shaded area to protect the plastic from harsh sunlight and clean it regularly to prevent mold and bacteria growth. Remember, this feeder comes with a 3 - year guarantee, so you can enjoy watching the birds without worry.
