JAVA WOOD: what is it and why is it great for birds? Java wood actually comes from old coffee trees that no longer produce coffee! They have many natural twists and knots which is great for bird perching because it helps strengthen their feet, preventing conditions like bumblefoot. A java wood perch also replicates their natural habitat. It’s super hard, very durable, and is naturally insect-free, making it a superior choice for bird owners. We carry a huge selection of java tree stands ranging from small table-top stands to large tree perches.
