Today is Bird Day. In its various incarnations, it draws attention to migratory birds in particular and encourages conservation of birds in general. Like all flying creatures, birds represent the element of air. For this reason, they often figure into travel spells. This can mean air travel but also applies to travel over land or water.
For this spell you will need a charm shaped like a feather or a bird (preferably in flight) and something to string it on, such as a necklace, bracelet, or key chain. Toss the charm gently in the air, catching it in your hand, and say:
Bird on the wing, bird in the air,
String the charm on its carrier. You can wear it to protect yourself, or attach it to a vehicle to protect that. If you put it on your key chain, you’ll always have it when you need it.
