Creating a perching wireor string line for birds.

Greetings! I wanna find out how I make a wire or string perching area for songbirds to sing while they perch or rest over my gardens. I also wanna create an area where they can go poop after the stuff they ate from my gardens such as berries and seeds so they can help the plant community thrive substainabily. I've never done it before, but I'd like to find out how. Natural places are hard to come by these days due to habitat destruction and so fourth. I wanna bulid a temporary place for birds to roost and perch during migration or hunting. If there are any ideas, please shoot back at me on this board. Love always comrades!

Please forgive me for my error. Creating a perching wire or string line for birds not the one titled from to that has wireor. My bad. Out!
