bird feeders.  

We have a huge garden and I think that we have about a dozen feeders in the garden, and we have lots of birds come for a free feed.
We also put up nesting boxes in the trees in the garden as well, and some of the birds have been using them all year round for a few years.
The most unusual bird we have seen in the garden is a Harris Hawk, it came into the garden and ate up the liver we had put out for the stray cat who visits, and its also been pinching the food left out for the foxes.

We used to have one. A very long time ago but it was taken down a while ago. As for getting birds to eat out of them, I really could not say. Sometimes birds will eat out of them. Other times, they will avoid them. I guess birds, like people, are fickle in many cases. The feeder would be good sometimes but the ground will do at others.
