Glad you asked...
Building an oriole feeder is pretty simple to do. Orioles are not very picky birds. They enjoy eating a variety of things including worms, bugs, fruits, nuts, seeds and suet. For this reason, you can simply create a small platform which is basically a small square of wood nailed to a pole which is then put in the ground. Food can be placed on the platform or certain pieces of fruit can simply be nailed to a tree.

Then again, this answer might help you...
Although you can build many types of feeders specifically for orioles, the most popular and common oriole feeder is the oriole jelly feeder. For more information look here: http://www.oriolefeeders.com/...;
