"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 - September 27 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.
