"Bye Bye Buzzard" Saturday
September 27 from 7:00 a.m. to 2:00 p.m.

          Saturday, Sept. 27, marks the 17th annual observance of our autumnal "Bye Bye Buzzards" event celebrating our migratory flock of Turkey Vultures. The birds spend Spring and Summer months here at the Arboretum; by late September the huge birds begin to depart, heading south to spend the Winter months in Mexico -- returning around early March. If you want to see our seasonal resident birds, make sure to arrive early - the Arboretum opens at 7 a.m. on "Buzzard Day" so early-bird visitors may join us for a chance to see the Turkey Vultures perched on the magma cliffs in the center of the Arboretum for the first hour or so after sunrise. Wildlife can be unpredictable, but usually our resident birds take to the skies by 8:00 or 8:30 a.m. and are circling overhead and away to roam and forage for the rest of the day. Visitors will be able to see a vulture up close and personal throughout the morning, though, thanks to the Arizona Game & Fish Department staff and wildlife rehabbers who bring "Ed the Education Turkey Vulture" and more charismatic mammals today for visitors to see.

          Turkey Vultures are fascinating birds, scavengers that are adapted to feast on roadkill and survive broiling Arizona summer heat. Usually by mid-March anywhere from 10-50 Turkey Vultures have returned from Wintering in Mexico to roost each night in our Eucalyptus grove and volcanic cliffs of the Picketpost Mountain escarpment, gliding away an hour or two after sunrise each day to forage for roadkill and other carrion. The birds typically reside here from March through late September before departing to spend fall and winter months in Southern Arizona and Mexico.
Turkey Vultures have a unique defensive technique: they vomit to repel a threat. Sure, their habits may be a little repulsive, but turkey vultures are a gentle, charismatic and misunderstood species and they're quite worthy of celebration.

          San Juan Capistrano boasts the seasonal migration of swallows -- but this corner of Arizona asserts its own bragging rights each year with the seasonal migration of the species Cathartes aura as they glide overhead on wings that span six feet. In past years our resident flock has been numerous, which is why the Arboretum allows early 7 a.m. admission at so visitors may view the vultures perched in the towering Eucalyptus trees and sunning themselves on the rocky cliffs of Magma Ridge.

          After sunrise the morning air warms and thermal columns begin to rise, the birds take wing and catch the upward spiral air currents - performing an impressive circling aerial ballet as they depart in search of carrion. On Bye Bye Buzzards Saturday, September 27, we'll gather at 7:00 a.m. to scan Magma Ridge for the birds, then at 8:30 a.m. take a birdwalk to learn about other species on the grouds. Another thrill for visitors is the display of live raptors, reptiles and mammals which is set up by volunteers from the Adobe Mountain Wildlife Rehabilitation Center. Melissa Reilly (at right) and other volunteers will bring "Ed the Education Turkey Vulture" and a variety of other birds; all can be seen near the Smith Building until about 2 p.m. so visitors may observe the wildlife at close range and learn about their biology, habitats and habits. "Ed" and the other birds are typically orphaned or lame animals which could not survive in the wild and are cared for by Adobe Mountain and also put on a mission to educate the public about wildlife. Expert Wildlife Rehabbers will be on hand to explain how they rescue and aid injured wildlife for release back to their habitats. Unlike vultures in the wild, Ed is habituated to humans. Living the comparatively easy life at the rehab center, Ed seldom needs to resort to feral vulture behavior such as vomiting at aggressors when threatened, or urinating down its legs and feet as a way to dissipate body temperature. Does that seem a repulsive adaptation? It has another useful purpose -- the strong acid of vulture excreta also inhibits the growth of bacteria on the birds' legs - an important evolutionary defense for a life spent amidst decay and disease. Events of our "Welcome Back Buzzards" Day are included with regular adult admission of $7.50, or $3 for ages 5-12.
