Birders are once again stirring to life. The summer doldrums are over and fall
migration is in full swing. While its true that some migrants
may be found headed north, south, east or west across North America
during any month of the year, the northward spring advance and southern
autumn retreat are the most notable and prolific migrations.
Birders around WNC are often roused from their winter torpor as early
as the end of March by the ringing song of the Louisiana waterthrush.
The pace heats up and becomes fast and furious from the end of April
until around mid-May then trickles on until about the first of June.
From June through July and into the first of August, we are left with
seasonal nesters and year-round residents. Fortunately for WNC birders,
we have a large number of warblers and other neotropical nesters to
brighten up our summers.
For those with access to proper habitat — mudflats and/or shallow
standing water — early to mid-August could produce early southbound
shorebirds. The sod farm and adjacent fields along Hooper Lane off N.C.
281 in Henderson County used to be a reliable spot for migrating shorebirds.
Recent changes in agricultural uses have apparently changed migration
patterns in that area, and Hooper Lane is more hit or miss now.
By the end of August, the few shorebirds are overshadowed by the multitude
of migrating neotropical passerines and growing number of migrant raptors.
Yesterday, while I was home for lunch, I noticed a lot of activity in
our holly tree. The holly is near the corner of the deck where we feed
and provides good cover for birds. There is a bird bath next to the
tree.
I retrieved my binoculars from the car and studied the holly. There
must have been at least 30 birds either in the tree or flitting to and
from it. Besides the regular resident chickadees, titmice and northern
cardinals, there were nine species of migrants: rose breasted grosbeak,
golden-winged warbler, black-throated blue warbler, black-throated green
warbler, chestnut-sided warbler, northern parula, Canada warbler, worm-eating
warbler and ruby-throated hummingbird.
Numbers of birds and species during fall migration easily match those
of spring but the birding is a bit different. There will be many immature
specimen plus many of the adults will be in fall plumage rather than
their spring finery. Birding by ear will be left to distinguishing chip
notes and call notes as songs will be virtually nonexistent. Still,
the sheer numbers make it an exciting venture.
For many birders fall migration means raptors. Places like Hawk Mountain
in Pennsylvania and Cape May in New Jersey see tens of thousands of
raptors (birds of prey) each fall between the end of August and December.
A couple of sites closer to home provide area birders a feel for what
hawk watches are all about.
Mt. Pisgah Hawk Watch at Mills River Overlook, milepost 404.5 on the
Blue Ridge Parkway, recorded 1,899 migrants last year, while South Carolinas
Caesars Head State Park, located on U.S. 276 just south of Brevard,
recorded 9,488 birds.
Broad-winged hawks make up the bulk of raptor migration in the east.
These hawks, unlike many that simply move farther south in North America
during winter months, are true neotropical migrants, wintering in central
and South America. They made up 1,674 of the migrants at Mount Pisgah
and 8,170 at Caesars Head. Over 2,000 broad-wings were reported from
Caesars Head on two different days during last years watch.
A couple of features, generally, make hawk watching unique in the birding
world. One is the fact that most hawks dont get airborne before
mid-morning or so. Since the larger raptors depend on thermals (rising
currents of warm air) they must wait till the air heats up. This appeals
to wannabe birders who dont realize 7 oclock comes twice
in the same day.
The second feature is that hawk watchers remain stationary waiting for
the birds to pass by. Along with binoculars and field guides, lawn chairs
and picnic baskets become integral parts of a hawk watchers gear.
There is an extraordinary site along the Blue Ridge Parkway that combines
exceptional fall passerine birding with the comforts of hawk watching.
Dwayne and Lori Martin of Claremont, N.C., discovered the site a few
years ago and have been monitoring it every autumn since.
At Ridge Junction Overlook, at the entrance to Mt. Mitchell State Park,
birders wait and watch as waves of migrating songbirds come down the
pass from Mt. Mitchell, then up and over the Parkway and on to points
south. The birds pause momentarily at the edge of the Parkway.
The Martins and Jerry Fedde of Hickory spent about three hours
at Ridge Junction on Aug. 26. They recorded over 225 birds, representing
30 different species. The list included 77 ruby-throated hummingbirds,
31 blue-gray gnatcathers and 26 black-throated green warblers.
Dwayne and Lori will be at the overlook almost every weekend from now
through October recording migrants. Anyone interested in observing this
phenomenon is welcome. Birders who wish to help tally are especially
welcomed.
While hawk watching accouterments like lawn chairs and picnic baskets
come in handy, some hawkers may be put off by the early
hours. The Martins say the most activity occurs between 7-9 a.m., but
some birds may be observed almost any time during the day.
Whether youre a seasoned birder or an interested novice, this
is a truly unique birding opportunity.
