The shorter perches attract only small birds such as finches since the large bird such as jays can't feed easily on the smaller perches. Larger perches attract both small and large birds. Thistle Feeder A thistle feeder is a specialized tube feeder. The ports on these feeders are extra-small to dispense thistle seeds. Also known as niger seed, thistle seed is a favorite of finches.
Thistle socks are an alternative thistle seed dispenser.
These thistle socks are made of cloth with small holes that are large enough for finches to pull the seed through. Suet Feeder Suet is animal fat that when consumed by birds provides them with a high energy source. This is especially a good item to put out during the winter time when higher energy sources will help birds maintain their body heat better. Many times suet will contain treats for the birds you hope to attract. Some commercial suet contains peanuts for the peanut loving birds, other suet contains berries and fruit, and some suet contains mealworms.
