Contemporary accommodations, up in the trees. That's a dining experience that many humans would envy. The Blomus BOREA Tree Mounted Bird Feeder is an angled stainless steel cylinder with a single plastic perch for avian diners. It attaches to trees quickly--and without damaging nails--via an adjustable nylon strap, which fits securely on trees from 8 to 23.75 inches in diameter. Blomus, headquartered in Germany, specializes in the design and manufacture of beautifully engineered home and office accessories in modern stainless steel styles.
