Background:
The Bellemont area of northern Arizona contains
a high concentration of wintering raptors,
with many birds using the northern
portion of the Camp Navajo Arizona
National Guard facility. The impact
of proposed land use projects have
on the ability of over-wintering raptors
to continue using this area is unclear.
Understanding why this northern Arizona
area contains a high concentration
of wintering raptors will prove useful
to both Camp Navajo and the surrounding
land management agencies.
Location:
Camp Navajo is located on the Coconino Plateau
about 10 miles west of Flagstaff, Arizona.
Approach:
Approximately 8 square miles of the northern
boundary of Camp Navajo is surveyed for wintering
raptors. This area includes non-forested
habitat, including meadows, open disturbed
areas, and park-like forests. We conduct
road surveys from late September to early
April to detect all raptor species along
the road network within Camp Navajo using
3 repeatable transects established in 2000.
These areas were surveyed each winter from
2000-2002 and we intend to survey again the
winter of 2003-2004. The location of each
bird was recorded with the aid of a global
positioning system and all flying raptors
were identified and plotted on a map, with
the type of flight patterns noted (flap-sail,
gliding, kiting, or soaring). We took special
care not to double count raptors. In past
surveys, red-tailed hawks made up majority
of the birds detected on the survey. To distinguish
the resident red-tailed hawks from the migrants,
we will attempt to capture and color band
all resident red-tailed hawks during fall
2003.
Benefits:
Winter raptor surveys conducted along the
same routes within Camp Navajo began in 2000
to establish a benchmark for long-term monitoring
on this military installation. Identifying
where raptors are spending their time (e.g.,
perched upon utility poles, abandoned buildings,
etc.) within Camp Navajo will allow managers
to mitigate any potential fatalities due
to electrocutions, building demolition, or
construction.
