Denali contains a rich diversity
of avian habitats. From Talkeetna northwest across the
Alaska Range to Lake Minchumina, a mosaic of habitats
exists ranging from low wet meadows to alpine fields.
Birds inhabit most of these areas including the seemingly
lifeless high altitude snowfields and glacial moraines
where snow buntings and gray-crowned rosy finches thrive.
The most commonly visited
areas of Denali include the mountainous regions of the
Alaska Range. This is a landscape shaped by glaciers and
erosion. In this area, most of Denali lies above tree
line and hiking is relatively easy in vast open landscapes.
Visitors that are more
adventurous may venture into the northwestern portion
of Denali, the Minchumina Basin, a land rich with wetlands
and multitudes of waterfowl. Hundreds of trumpeter swans
nest in the Minchumina Basin each year.
Denali is a vibrant landscape
that is constantly changing. By the end of the next century,
visitors to Denali may encounter a place much different
from that explored by Charles Sheldon in the early 1900's.
It is unclear how global climate change will affect birds
and their surroundings in Denali. It is clear, however,
that Denali's habitats are dynamic and that shifts in
the abundance and distribution of vegetative communities
will likewise affect the abundance and distribution of
birds across this great northern ecosystem.
The following images are
representative of the major bird habitats found in Denali
National Park & Preserve. |
|
Denali's
wetlands host a variety of waterfowl and shorebirds
such as geese, swans, ducks, cranes, sandpipers, and
gulls.
|
.
|
|
Bogs,
consisting of low shrubs and shrub-graminoid communities,
are common in the lowlands and support a suite of passerine
species.
|
 |
| Tussock
sedge habitat presents a challenging landscape to birders.
Whether balancing atop a wobbly tussock or sinking knee
deep between them, bird-watching is difficult in this
bumpy environment. In addition, buzzing mosquitoes can
often interfere with the ability to hear bird songs. An
abundance of white-crowned sparrows awaits those hardy
souls who mount an expedition across these undulating
landscapes. |
|
| Loons,
grebes, waterfowl, and shorebirds are found throughout
Denali's lake and pond habitats. |
 |
| Waterfowl
and shorebirds hide in the lush vegetation found around
the shorelines of many ponds and lakes. |
 |
| Riverbar
& Riparian Areas |
|
Semipalmated
plovers roam the vast riverbar habitats spread across
Denali National Park & Preserve.
|
 |
|
Common
to Denali's numerous riparian and stream habitats are
harlequin ducks, wandering tattlers, and American dippers.
|
 |
 |
| Shrub
communities are widespread in Denali and range from dwarf
to tall varieties. Shrub habitats in alpine areas predominately
consist of small species such as dwarf birch. |
 |
| Bird-watching
can be a challenge in medium and tall shrub covered landscapes.
Dense alder thickets are difficult to move through and
sight is often limited. Unexpected close encounters with
wildlife can, and do, occur in these areas. A birder must
use extra caution when traveling through heavily vegetated
terrain. |
 |
| Tall
shrub communities occur along rivers, drainages, and near
treeline. Predominately made up of willows and alders,
these areas are usually great for birding. A variety of
species including arctic warblers, gray-cheeked thrushes,
and several types of sparrows can be found in tall shrub
habitats. |
 |
 |
|
The
major forest types of interior Alaska (needleleaf, deciduous,
and mixed) are found in Denali. Black-capped and boreal
chickadees, ruby-crowned kinglets, Swainson's thrushes,
yellow-rumped warblers, pine grosbeaks, and dark-eyed
juncos are common forest species.
|
 |
|
The
majority of Denali's forests are made up of smaller
black and white spruce. Stands of these small conifers
are found across the landscape. Don't let the size of
these trees fool you. A 10 meter high tree may be well
over 200 years old.
|
 |
| The
forests of Denali encompass a few hardy species well adapted
to life in the north. Towering white spruce and cottonwood
are found along streams and rivers on the south side of
the Alaska Range while narrow strips of smaller spruce
(right) line many of the rivers at lower elevations on
the north side of the range. |
 |
| Deciduous
forests are not common in Denali. Where they do exist,
poplar, aspen, and birch are the dominate species. Birds
in these areas include woodpeckers, thrushes, and warblers. |
 |
 |
| Views from Denali's alpine habitat are stunning. Travel on open alpine landscapes is relatively easy and the insects are at a minimum. The greatest challenge facing the average birder may be resisting the urge to take a hillside nap in the sun. Fortunately, the sun will still be there afterwards! |
 |
| Alpine
habitat offers some of the most colorful birding in Denali.
Here you'll find American golden plovers, northern wheatear,
Lapland longspurs, and long-tailed jaegers all breeding
amongst a myriad of alpine wildflowers. |
 |
| On
the margin between soil and stone, species such as surfbirds
and gray-crowned rosy finches return each year to nest
and raise their young. |
|
| Rock
Outcrops & Talus Slopes |
| Rock
outcrops, cliffs, and talus slopes make up much of Denali's
environment. While extreme by most standards, this habitat
hosts a variety of bird species. Across a landscape dotted
with wildflowers and endless fields of stone, Say's phoebes,
golden eagles, gyrfalcons, and rock ptarmigan abound.
|
 |
| Walking
on talus (rock debris) slopes can be challenging, but
the rewards are great. Beautiful scenery, an escape from
the mosquitos, and the chance to see bird species rarely
found at lower altitudes are just a few reasons to visit
this spectacular habitat. |
