Wherever you build your oriole nest, pick a sturdy branch. Remember, you and your eggs and babies will be stuck deep inside your purse-shaped nest for the next 5 weeks, so be careful to pick a spot that's safe, cool, and comfortable. Gather Materials A. Long fibers. This includes grasses, hairs from horse tails and other long animal fibers, string, yarn, thread, or thin twigs. B Springy fibers.
Milkweed stems and grapevine bark are examples.
C. Soft, downy fibers. You will carry one fiber at a time to the nest. Hang onto the nest twig with your feet as you wind the first long strand around the twig loosely with one or more turns. Bring the next fiber to the branch and wind it around the twig weaving it around the first fiber. Keep adding fibers and weave and tie knots in them until in 2 or 3 days you have a tangled mass of fibers hanging from three or four places on the twig.
