Details:
A 2" X 12" board is screwed to each arm of a plastic lawn chair. The 1/2"  screw goes up through the arm into the wood. The plastic Cups have 1/2" screws going down into the board.

The Shirt is held in place with Clamps as shown. The Hat is hung on a wire that's bent up from the back of the Lawn Chair. The end of the wire has a loop bent into it like a halo to hold the Hat.

The Chair is put near your regular Feeder which Birds have been visiting. Pick a location with shrubbery or twigs near the Chair so Birds can land there. The Cups are kept filled and the regular Feeder is allowed to get empty. Soon the Birds will be visiting the Cups instead.

Birds feed most actively just after sun-up and about an hour before sundown, depending on your locality. Plan to man the Lawn Chair at these times. Tie your pets and tell your family not to disturb you. Use drab clothing; beige, brown, and camouflage are fine.

Remove the Hat from the wire and wear it low over your eyes. Sit right down on the clamped Shirt. Be still as a rock. When a bird approaches you, close one eye. They seem more trusting of a 1-eyed Creature. Don't become impatient. "All good things take time".

Expect to sit at least a half hour. You may have a relatively tame bird come to eat rather quickly, or maybe yours are timid and may take more time. But the results are worth the effort. After they start eating from the Cups, put Seeds in your outstretched hands.

Songbirds can be taught to come to a sound you make. If you always tap on the feeder, or whistle or sing or call, they will associate this sound with food, and learn to come when they hear it.
Bluebirds, Robins and Woodpeckers are attracted to Mealworms, which are easy to raise from stock bought from a supplier. Bluebirds are seldom attracted to Bird Feeders, so they require special treatment.

To tame Bluebirds, put a rather large container, like an inverted garbage can lid, near your active Bluebird House. Use a dozen Mealworms from a refrigerated container so they will not be overactive. Provide some shade, or the Mealworms may ecsape or die.

Soon the Bluebirds will notice the Mealworms and begin feeding on them. As soon as the container is empty, replace it with a smaller container and another dozen Mealworms. This new container should be about 6" wide by 2" high with straight slippery sides to confine crawling Mealworms.

You can change the location of the new Mealworm container by gradually moving it as much as 20 feet between fillings toward your planned location. The eventual location can be under the edge of a shade Tree or even the edge of your porch. Keep in mind that Bluebirds are  more inclined to feed in open areas.

You may want to gradually move the container to a window sill. Then you can sit inside with the window open just enough for your arm to hold the container outside. As the Bluebirds become accustomed to your arm, you can gradually open the window until you are in full sight.
Then move your chair right outside the window, and be patient.

Very early Spring may be the best time to tame Songbirds, when natural wild food is least available. Later you may notice a dwindling of your Beggars, as they pair up with their own kind, and search out vacant territories to pursue their Biblical mission of raising young to perpetuate their species.

It's novel to have a "wild" Bird follow you like a domesticated pet. You may have to wear a Straw Hat with a deep crown to have a place to put Bird food, so you can get some outdoor work done with your hands. Let us know how you make out.
