Window feeders attach to a pane of glass and allow you to see the birds while they are feeding from the comfort and warmth of your house. It may take slightly longer for the birds to feel comfortable feeding in this way but soon you'll have a variety of birds feeding right next to your living room window!
The final types of bird feeders are the suet feeder and nectar bird feeders. Suet feeders are usually consist of a wire cake that suet cakes are attached to - suet feeders can be difficult to clean but do attract a variety of birds in winter and summer. Nectar bird feeders are diesgned to attract hummingbirds and Orioles. The birds 'suck' a sugary water from an inverted bottle or from a saucer that drips the liquid through the feeder.
It's often worth having a selection of bird feeders in your garden to attract different types of birds at different times of the year. If you buy bird feeders that have been built well, they should last for a number of years and bring you lots of pleasure.
