Hoods for feeders are used to protect your seed from weather conditions and, if they are large enough, protect it from squirrels. Products like the Aspects’ Tube Top and Tube Top II are slotted on top to slide over the feeder’s hanging wire. This enables the hood to sit right on top of the tube feeder providing the maximum weather protection. Most hoods feature a hook above and below so various feeder styles and sizes can be hung from them. They are less specific but also more limited in their protection.
