Purchase a dish made from a melted wine bottle, or make your own by firing a favorite bottle in a pottery kiln. Use this as a dish to hold birdseed or suet, and use it to attract birds to a level space, such as a picnic table or window ledge. For added security, tack down the glass dish using office tack to ensure that it won't go flying and break as a result of high winds or overenthusiastic avian eaters.
Make an upside-down seed-dispensing feeder by shaping wine corks. Use an oscillating power tool to partially hollow out an artificial cork, making a wide cylindrical hole that runs from the portion of the cork inside the bottle almost to the top of the cork. Cut a hole in the side of the cork attaching to this chamber to allow seed to fill the chamber inside and be available to the bird; fill with a thick seed, such as a mix with sunflower seeds, to ensure that the seeds fill the lower chamber but don't spill out. Use thick wire or part of a wire coat hanger to fashion a perch for the birds to use while they eat, attaching it to the mouth of the bottle above the cork and wrapping it down below the cork.
Make the wine bottle into a hummingbird feeder by creating a double-layered, dispensing lid. For this project, start with a wine bottle that has a screw-on cap, rather than a cork, and cut a dime-sized hole out of the top of the lid. Attach this lid top-down to the inside of a wider lid (such as a sports drink) using four quarter-teaspoon balls of epoxy putty. Position the putty pieces evenly around the outside perimeter of the large lid, then place the smaller lid over them, attaching the lids while leaving a tiny amount of space between them for the sugar water to flow into the large lid once the bottle is hung upside-down.
Make a combo feeder for both hummingbirds and other fowl by building the hummingbird feeder above, then coating the outside of the bottle with a combination of birdseed and suet or peanut butter. Larger birds will eat this while the hummingbirds enjoy the sugar water.
