Nestled in the southern half of the Loess Hills,
Hitchcock Nature Center (HNC) is a former YMCA camp that has a
become a county park and is managed by the Pottawattamie County
Conservation Board (PCCB); HNC provides spectacular views of the
Loess Hills and the adjoining Missouri River Valley. The Loess Hills
tower hundreds of feet above the flat valley floor on their imposing
west face and reach a height of 1200-1400 feet above sea level. The
Loess Hill themselves are a nearly unique land formation in North
America; they are composed of windblown soils deposited long ago on
the eastern side of the Missouri River Valley by prevailing westerly
winds. The landscape at Hitchcock Nature Center today is a rugged
mix of prairie remnants, forest, and Bur Oak savanna. An active
program of controlled burns to restore prairie is underway at the
site. Privately-held lands adjoining the nature center include
wetlands, a small lake, and larger prairie remnants. These lands are
generally off-limits to birders but crucial parts of them can be
scoped from within the nature center or from other accessible areas.
HNC is located about ten miles north of Council Bluffs, Iowa near
the small town of Crescent (which has good eating options including
Henry's Diner and The Pink Poodle...). The city of
Omaha, Nebraska is easily visible from the HNC Lodge and from the
Hawk tower off to the southwest. A number of other excellent birding
sites are also within easy driving range of Hitchcock (in both Iowa
and Nebraska)-- the DeSoto and Boyer Chute National Wildlife
Refuges, Lake Manawa, the Mid-America Ponds, Fontenelle Forest,
Neale Woods, etc. HNC is best known to Iowa birders for its
excellent fall raptor flights. Hitchcock is one of the few active
hawkwatches on the the Great Plains and, apparently, the best one.
Annual autumn counts of southbound hawks, eagles and vultures are
conducted at the site through a joint effort by the Pottawattamie
County Conservation Board (PCCB) and the Hitchcock Hawkwatch
Association (HHA)--a volunteer group of birders/hawkwatchers.
Funneled past Hitchcock by the updrafts created by the hills and by
the north-south channel of the Missouri River Valley, raptors and
other avian migrants overfly the location in large numbers in the
fall. On “big days” the birds can seem to fill the sky in a
spectacular manner. HNC's fairly central location on the North
American continent also promotes migratory diversity; western,
eastern, southern, and northern species all appear here. Spring
raptor flights occur at HNC as well, but are a pale echo of those
seen in the fall and no organized raptor counting is done at
Hitchcock in the spring.
The Hitchcock Nature Center HawkWatch (HNCH) began in 1992, when
Loren and Babs Padelford, working in conjunction with widely-known
raptor biologist Jon Stravers, founded the fall hawkwatch-- with the
Padelfords counting migrating hawks from the deck of the HNC Lodge.
In recent years, the hawkwatch has developed a larger volunteer
pool, employed a weekday counter (funded by the PCCB), and now uses
a new 50 foot hawk tower (the construction of which was funded by
the Iowa West Foundation) adjacent to the lodge to conduct counts.
Counting is part-time between 15 August and the beginning of
September, but is full-time (daily) between 1 September and 20
December. Flights generally begin around 10am and end around 6pm
during the peak of the fall season in late September and in October,
but weather conditions can alter this daily timetable dramatically.
Hawkwatch festivals are held at HNC in October and November
annually.
Raptor migration is generally modest until around 20 September, when
the flight begins in earnest. This “prime period” lasts until around
20 October. In the recent years of full-time coverage (600-750 count
hours per season), the HNC hawkwatch has averaged around 13,000
raptors and vultures of nineteen species annually. In 2005, over
16,000 raptors and vultures of twenty species were counted.
Red-tailed Hawks, which appear in an amazing variety of morphs and
subspecies at Hitchcock, are generally the most abundant raptor
migrants followed by Turkey Vultures, Swainson's Hawks (which
tend to appear in very big numbers between 27 September and 5
October annually), Sharp-shinned Hawks, and Bald Eagles (which
dominate the 15 November—20 December late season at HNC). Other
common raptor migrants at various times during the fall season
include: Ospreys, Northern Harriers, Cooper's Hawks, Broad-winged
Hawks, and American Kestrels. Uncommon and occasional annual
migrants include Mississippi Kites, Northern Goshawks,
Red-shouldered Hawks, Rough-legged Hawks, Golden Eagles, Merlins,
Peregrine Falcons, and Prairie Falcons. HNCH's rarest annual
raptor migrants are Ferruginous Hawks. Black Vultures
have been recorded in two of the last four HNCH seasons.
North or northwest winds are generally best for hawkwatching at HNC,
but during prime period (20 September- 20 October), in particular,
good flights can occur during a broad spectrum of conditions. A wide
array of avian species ranging from Red-headed Woodpeckers and Blue
Jays to American White Pelicans and Franklin's Gulls can be seen
migrating past the site (at times in huge numbers for certain
species) in the fall along with the raptors.
While the fall raptor flights are clearly Hitchcock's main birding
attraction, HNC and the surrounding areas have much else to offer in
terms of birding. The lands adjacent to HNC also have some excellent
habitat, but, as noted earlier, are privately owned and off-limits.
Parts of theses lands, however, can be scanned from nature center
lands or from public (gravel) roads nearby. There are also a number
of good birding trails at the nature center itself including the
Habitat Loop Trail, Badger Ridge Trail, The Chute Trail, The Hidden
Valley Trail, and the very physically demanding Westridge Trail
(which also boast the best views and prettiest terrain in the park).
Some of the other best birding spots (excluding those on private
land) include two driving routes near the nature center-- the
Missouri Ave-152nd and Ski Hill Loops. The main road at HNC itself,
Page Lane, is also well worth walking or driving at any time of
year. There are two prairie overlook decks at Hitchcock, one off
Page Lane and the other at the campground, that are also well worth
stopping and scanning.
Spring passerine migration at and around HNC, particularly in May,
can be quite interesting. Hitchcock is a solid, if not spectacular,
warbler spot with huge numbers of Yellow-rumped Warblers and a broad
sprinkling of other species annually. Other types of neo-tropical
passerines, however-- thrushes, flycatchers, vireos, orioles,
buntings, grosbeaks, sparrows, and tanagers, seem to turn up
annually in excellent numbers and variety. This is a good area for
Western strays, which in the last couple of years have included
sightings of Lazuli Buntings, Spotted Towhees, and Black-headed
Grosbeaks.
Summer birding at Hitchcock can be a very rewarding experience as
well. Nearly 100 breeding species can be found at or near Hitchcock.
Lark Sparrows are often found near the campground and along
Badger Ridge trail. Black-billed Cuckoos can be more
difficult to locate away from a couple of generally no access spots
on private land, but are found at times along the Habitat Loop and
Hidden Valley Trail. Blue Grosbeaks and Western Kingbirds
are commonly found along the two driving loops between June and
mid-August. Wood Thrushes and Whippoorwills are common
breeders at the nature center itself. Grasshopper Sparrows
and Bobolinks can sometimes be found from the Prairie
Overlook Deck near the campground. Bell's Vireos and
Yellow-headed Blackbirds breed on adjoining private land and can
at times be seen or heard from the Missouri-Ave-152nd driving loop.
Willow Flycatchers can be found along both driving routes.
Scarlet Tanagers and Cooper's Hawks are most commonly
seen along the buggy trails in the valleys but can also be found at
times along Page Lane itself. Yellow-throated Vireos and
Blue-gray Gnatcatchers are found along the most remote parts of
the rugged Westridge Trail. Other more sporadic summer residents in
recent years have included Summer Tanagers, Broad-winged Hawks,
and Acadian Flycatchers.
Winter is generally the least productive birding season at HNC, but
the Missouri-Ave-152nd loop can be quite interesting even then; the
nature center itself also usually holds good numbers of Purple
Finches, and Hermit Thrushes, Spotted Towhees, and
Townsend's Solitaires have been semi-annual in recent years.
