Birds help keep our ecosystem healthy, so help keep birds healthy too with the More Birds Bird Health+ collection. Bird Health+ products are made of bird-safe, BPA-free materials and recyclable parts. The More Birds Bird Health+ Big Gulp Hummingbird Feeder features a glass nectar bottle and a colorful red top and base with four integrated perch feeding stations. The built-in ant moat stops ants right in their tracks, keeping precious nectar fresh for hungry hummers. With a 40-ounce large nectar capacity, the Big Gulp provides plenty of nectar to keep hummingbirds happy and coming back for more! The wide bottle opening and detachable flat base make filling easy and cleaning a breeze. When cleaning your hummingbird feeder, do not put your feeder in the dishwasher, as the high temperatures can permanently damage the feeder parts.
