Across what is now the mid-west United States in the late 1830s and early 1840s, there was an over abundance of labor, scarcity of money and farmers were unable to sell crops for a good price at market. Nearly all citizens were engaged in trade and bartered for goods and services with little chance of turning a buck. The high rate of unemployment in the states like Illinois, Missouri, Iowa and Tennessee had people looking for new places to grow roots and build a new life. For many residents, Texas fit that bill.

Quite a few Americans got a good look at Texas real estate firsthand either through the service during the Texas Revolution or from the Mexican War a few years later. One such Mexican War veteran and Illinois resident was Allanson Dawdy. Born in 1826, he left home at the age of 20, in 1846 to join the United States Army under command of Colonel JJ Hardin. Men from all walks of life were brought together creating a volunteer army from laborers, farmers, blacksmiths, lawyers and doctors. They saw action at the famed Battle of Buena Vista against General Antonio Lopez de Santa Anna himself, in what has become one of the most well known battles of the Mexican War. Dawdy, a young man of 21 liked what he saw in Texas and after his military service planted roots here in Dallas County. His name, now misspelled as Dowdy became the namesake of one of the most well known roads in Dallas, Dowdy Ferry Road.

The parkland here was first settled by William Shelton in the 1840s, an Illinois veteran from the Mexican War. The bluffs carried his name, Shelton's Bluff until shortly after the Civil War. In 1850, he married into the Dawdy Family who ran a ferry service on the Texas National Highway across the Trinity River downstream a few miles. Pronounced "Dowdy", the misspelling took and Dowdy Ferry Road is now over the old Texas National Highway route.

Together only three families, Beeman, Shelton and Dawdy owned most of the land along the Trinity just south of what is now Fair Park to Hutchins, in what was then Nacogdoches County in the Republic of Texas. The McCommas family purchased the Shelton land after the passing of William Shelton. The name Shelton's Bluff stuck through the Civil War, eventually changing names to McCommas Bluff on maps in 1880. 

Illinois native Allanson Dawdy (1826-1901) came to Dallas County in 1847. By 1854, he was granted a license to operate a ferry at this site on the Trinity River, the southernmost crossing at the time in Dallas County. An important route for citizens living on both sides of the river, the ferry continued in operation until about 1880. Ferry charges included one dollar for a wagon with four or more animals, ten cents for a man and horse, and five cents for a person on foot. The first permanent bridge was installed at this site in 1888.

Now spelled and pronounced Dowdy Ferry, the road and bridges bearing the name form a wide arching loop from Pleasant Grove towards Hutchins. 


Black Bellied Whistling Duck Dendrocygna autumnalis aka Pato Maizal  "The Cornfield Duck Of Mexico"

It's a rare sighting for Dallas, tropical Black-bellied whistling ducks, also known as black-bellied tree ducks, are odd birds and an odd sight. Taxonomists categorize them closer kin to geese than true ducks. They don’t dabble. They don’t dive. They wade in shallow water with their spindly legs and use their long necks to bend over to graze on grasses and aquatic vegetation.

Beautiful in flight, these dark chestnut-brown birds have bright-white wing patches with a pinkish-orange bill and feet that hang behind them. Hens and drakes share similar patterns with a slight deeper contrast in color for the drakes. While flying, they can not be confused with the buff-colored fulvous whistling duck also found in the same regions – or any other duck, for that matter.

These birds are found in great numbers across Central and South America where, in some locales, they are referred to as “Cornfield Ducks” as they plague grain fields and are treated as such. In the US, their range is limited to the southern limits of the Gulf Coast states, though wayward birds have been found in northern states. Their population is actually expanding north and why they are now infrequent visitors to the Trinity River Bottoms.

Whistlers don’t migrate, in the true sense of waterfowl, but they flock up in groups to travel back and forth across their range. As the moniker “tree duck” implies, they nest in holes of trees, and their webbed feet have needle-sharp talons to help them perch on branches. There’s also a reason they are known as whistling ducks. They are very vocal; their peeping whistling while in flight betrays their approach.

Tri-Colored Heron Egretta tricolor

Another seldom seen bird in the DFW area is the Tri-Colored Heron formerly known as the Louisiana Heron. Up until several years ago their range was thought to be that of Southeast Texas, Big Thicket and the huge expansive swamps of the Gulf Basin. If you know where to look, you just might find one in the Great Trinity Forest.

The Tri-colored Heron is a medium-size wading bird named for its three main colors: bluish-gray, purple and white. Its head, back and wings are a dark bluish-gray. The back of the neck is purple. The belly is white. The Tri-color also has a narrow white streak with delicate rust-colored markings down the front of its neck. The eyes are bright red. The legs are pale green or yellow. The bill is usually yellow at the base and has a dark tip

Tri-colored Heron making a surge in deeper water for prey


 Foraging in open or semi-open wetland areas, the tricolored heron tends to hunt in deeper water than other heron species, feeding mainly on small fish but also eating insects, crustaceans and frogs. It uses a variety of hunting strategies, including standing still, patiently waiting for prey to come within striking distance, and a running pursuit with the head held low to the water and the bill stabbed at prey with an almost horizontal action

The Tri-colored Heron is more active than the larger herons. This bird does not patiently stand and wait when feeding. It walks through shallow water in a darting fashion, crouching and weaving as it moves along. Sometimes it raises its wings to cast a shadow on the water so it can spot its prey. It lunges and prances, then shoots its bill into the water to catch a fish or an aquatic insect.

Rastro del Caballo -- No Bueno
Worst trail in the Great Trinity Forest? You bet. Worst built trail in DFW? Most likely.














Much of the trail here is a scraped bulldozed path through the woods cut in the spring of 2013. Six to eight feet wide in most spots it's about a mile and a half long. No formal signs exist and it loosely follows the Trinity River. From the parking lot the trail travels near due west till it reaches a high bank with a view of the mouth of Five Mile Creek.


Sand ballast added to the underlying clay in an attempt to dry up some of the worst mud sections. Notice how the sand has migrated out into the woods, causing more of a problem.

It sits off the "new channel" of the Trinity, a channelized section of river that was straightened in the 1970s for a planned inland barge route that never materialized.

The woods here are a rather remarkable stand of Ash, Pecan and some large Bur Oaks. The Virginia Wild Rye has just about gone to seed as of this writing in late May and will soon turn from brilliant green to a uniform color of khaki brown.

The trail itself was built slightly below grade. When scraped/bladed the trail was a natural depression which tends to hold water for extended periods. A year ago I remarked on my blog about the problem and thought one good overbanking flood or two would turn it belly up and ruined. Still waiting on that big flood.

Allanson Dawdy who founded Dowdy Ferry and many of the old pioneers never built horse trails and roads through this area for they knew that with any rain, the clay mud becomes an unworkable mess for weeks on end. The old timers picked the high ground, up in the sand and out of what we now call the hundred year flood plain. Old stories of hunters and fisherman in this area never mention horses, it was always traveled on foot.

Somehow we as modern day Dallasites forgot this lesson and as such created a problem with no good solution. Food for thought if anyone else has a hankering for building horse trails down yonder.

Out of the dozen horses at the park that day, only one ventured down the trail. The rider came back in five minutes and yelled "No Bueno" to the rest of the horseback riders. They were frustrated but understood that it's not worth injuring your beloved horse on a poorly built trail. They hit the dirt road up to McCommas Bluff instead.
Hitched to a post near the trailhead, these horses were not taken on the horse trail through the woods due to ankle busting conditions of the trail. They were ridden up the old dirt road instead

The road here is actually a right of way for a utility sewer line that sends sewage down to the wastewater treatment plant in far Southeast Dallas near the community of Sand Branch.


The open vistas of immense horizon-to-horizon coneflowers are an impressive sight this time of year. Soon the Giant Ragweed will takeover, growing to impressive heights of 8 feet or higher through this area. This same ROW if followed through McCommas Bluff Preserve will lead you across Elam Creek and will link up with Phase II of the Great Trinity Forest Trail just north of the pedestrian bridge across the Trinity near the Audubon Center.

Lemon Beebalm along the doubletrack trail at Dowdy Ferry
Known by a number of common names, lemon beebalm is a 1-2 ft annual with unusual, tuft-like, lavender to pink, spiked flower heads. Each elongated spike is punctuated by whitish or lavender, leaf-like bracts. Several stems grow from the base and are lined with pairs of spear-shaped leaves.  Horsemint has a distinctive citrus or lemony scent when the leaves are rubbed or crushed

There must be at least 3-4 distinct subspecies of lemon bee balm aka Horsemint in the Great Trinity Forest. Some stands near Joppa Preserve are larger, rougher and nearly white, while others near Scyene Overlook have a deep purple appearance. The Dowdy Ferry Park is somewhere in between the two. All attract butterflies, hummingbird moths and bumblebees for the nectar.

White Faced Ibis and Migrating Wading Birds at Joppa Preserve

The Texas White Faced Ibis a State Threatened Species in Dallas, Texas May 23, 2014
Certain shorebird and wading bird species are the first push of migratory Central and South American birds through the Great Trinity Forest every year. They are only seen for a brief time as flock after flock stop to refuel for a day or even just an evening in the small ponds and wetland habitat along the Trinity River.

The birds in many cases have flown the entirety across the Gulf of Mexico over water from the Yucatan to the mouth of Trinity Bay, non-stop. Others have flown across the Andes and the Sierra Madre working their way up the tidal pools and mud flats of the Pacific. Here they are, for a brief moment in time, in Dallas.
Little Lemmon Lake full of shorebirds
The drier than normal spring in 2014 has been harsh on many aquatic species and waterfowl. What is poor for some species is great for others. The mudflats of the half empty ponds and small lakes like Little Lemmon Lake in Joppa Preserve provide near perfect habitat for these birds.

Rare birds call this place a brief home, a roadstop motel of a place.

One such species, listed in Texas as a Threatened Species, the White Faced Ibis is a very rare sight to Texans.

 The White-Faced Ibis is a long-legged wading bird with reddish eyes and a long, slender, decurved bill. Plumage is chestnut colored with green and purple iridescent. During the breeding season, a white feather border can be seen around the base of the bill along with red lores and legs. Juveniles lack the white on the face and the red legs.


To Dallasites the bird is very rarely if ever seen. A "life bird" for many who keep a checklist, seeing one in the wild would be a year's highlight for many birding types.



The White-Faced Ibis is threatened due to habitat loss. It needs wetland areas exactly like those in the Great Trinity Forest to thrive.

The shallow wading pools in short grasses, flooded marsh and lowland areas are their prime habitat. Very few of these places still exist. It's a real gem to have places like that here in Dallas.

Appreciated by few humans but adored by wildlife, the next year or two will tell the tale whether or not changes to the Trinity Forest will be impacted by construction plans.




American Avocet Recurvirostra americana

With its unique coloration, long legs and elegant profile, the American Avocet is striking among North American birds. The Avocet is a migratory shorebird that is characterized by a long, thin upcurved bill with distinctive black and white markings on its back and sides

The American Avocet or Recurvirostra americana is a long legged shorebird in the stilt family. It is considered a large shorebird at eighteen inches in length.  The Avocet is charecterized by a long, thin bill that curves upward, more so in the female.


Year round it has a distinctive and signature black and white stripped pattern on its wings and back.  During the breeding season the head and neck are a pinkish-tan.  During the winter they turn more white.





American avocets prefer open water and marshy summer habitats such as lakes and ponds throughout the central plains of the United States, including the Rocky Mountain region and Canada.

During the winter avocets  migrate to saltwater or brackish areas of the central and southern California coast, Baja California and the southeastern Atlantic coast as well as throughout Mexico and the Caribbean. Year round populations can be found along the South Texas coast and the southern California coast.













American Avocets forage while wading in shallow water by sweeping their curved bills back and forth along the surface of the water, or they can use their bills to probe into mud for insects or crustaceans. They may feed in flocks, and may dabble for food in deeper water.


Avocets are important members of their ecosystem; because of their food habits they likely have a regulatory influence on insect and crustacean populations, and they are an important food source for their predators. They also have an influence on the plants they eat as they often broadcast seeds into new areas.






Currently protected by the US Migratory Bird Act, American Avocets are making a comeback after over-hunting in the 19th and early 20th centuries. The main threats to American Avocets today are habitat loss and degredation.














Foraging With Migrating Shorebirds

Plate by Alexander Wilson circa 1807

Often called the "Father of American Ornithology", Alexander Wilson 1766-1813 was instrumental in the early scientific study of birds in what is now the Southern United States. His sketches and plates were some of the first that featured the American Avocet, Lesser Yellowlegs, Roseate Spoonbill and various small shorebirds.

A number of bird species now carry the "Wilson's" name as an honor to the man who first studied them at length.

Wilson authored the nine-volume American Ornithology (1808–1814). Of the 268 species of birds illustrated there, 26 had not previously been described.








Lesser Yellowlegs Tringa flavipes

In winter, the Lesser Yellowlegs is found along the coasts of Mexico, Central America, South America, and the Caribbean. The largest concentration of wintering birds occurs in Suriname and along the Gulf of Mexico.

Lesser Yellowlegs breed in interior Alaska and northern Canada. They breed between 51 and 69 degrees north latitude in suitable habitat. They breed farther north than their close relative, Greater Yellowlegs (Tringa melanoleuca), where they co-occur. Historically, some populations of Lesser Yellowlegs might have bred farther south then they do currently.




Wilson's Phalarope Phalaropus tricolor
Wilson's Phalaropes are a relatively small, long-legged shorebird. They are unique among Texas birds in that they are one of only a few species in which the female is much more brightly colored than the male.

The Wilson's Phalarope can be distinguished from most other shorebirds by the bright coloration on their neck and head. Additionally, unlike other shorebirds, Wilson's Phalaropes often feed while floating on the water, sometimes spinning like tops to stir up aquatic invertebrates.  

The relatively long, thin bill, and bold blackish stripe on the neck and face distinguish the Wilson's Phalarope from the red-necked phalarope (Phalaropus lobatus), which is a migrant in Texas.







In Texas, Wilson's Phalaropes are most frequently found in wet prairie, flooded plains and other grass or sedge dominated wetlands. The presence of short vegetation in or adjacent to shallow pools of open water is an important microhabitat feature. Human-altered habitats, particularly flooded pastures and municipal wastewater treatment  ponds, may also provide suitable habitat.
















Because microhabitat conditions are very important to the Wilson's Phalarope, water conditions greatly influence habitat use. The shallow wetlands on which this species depends are very sensitive to alteration, especially drainage and degradation resulting from human activities. When water levels are low, wetlands may be avoided due to the lack of standing water. Wetlands dominated by shrubs are also avoided by the Phalarope due to the increase risk of predators.

Artificial habitats, such as flooded agricultural fallow fields, may be utilized by Wilson's Phalaropes because they provide necessary conditions lacking in native habitats.

Killdeer Charadrius vociferus

The killdeer is Texas most well-known member of the plover family, although many people know the killdeer without understanding its family affiliation. The killdeer can be common around human developments, frequently seen on playing fields, parking lots, and other unnatural habitats. Its “broken-wing” display is famous and known by many.

The killdeer often forms flocks after breeding in late summer. It feeds in fields and in a variety of wet areas, and in general, it is not prevalent on mudflats. It is noisy! Breeding residents to North Texas they are a common site.


Spotted Sandpiper Actitis macularius

Spotted Sandpipers are the most widespread sandpipers in the United States, having colonized their broad breeding and winter ranges by using  almost all habitats near water. These include the shorelines of large rivers and lakes to urban and farm ponds.

Spotted Sandpipers (Actitis macularius) are found throughout North and Central America, including the western Caribbean islands. Their breeding range extends from the northern Arctic to the southern United States. Their wintering grounds range from the extreme southern United States to southern South America, along with all the Caribbean islands. Spotted Sandpipers live year-round along the western coast of the United States and in parts of California.

The Spotted Sandpiper is a common migrant throughout the Lone Star State from late March to early May. The fall migration period extends from early July to mid-October. Absent in the hottest of summer months, they are quite common in the Great Trinity Forest ponds in the late summer and early fall.

These sandpipers are winter residents in Texas with  abundance varying from common to rare depending on latitude and climate.
