An exploration of natural history.
My wife Diane and I live in Salisbury, high on the Piedmont plain of North Carolina. We enjoy all aspects of the natural world. Most of our time is spent in the Southeast but occasionally we travel to other parts of the country and the world. Here are some of our observations as we seek to become compleat.
On our family trips to Florida, we always like to visit Orchard View Park in Delray Beach. This 6-acre park is tucked between a fire station and an elementary school. It has a loop trail, a playground, picnic tables and nice mix of native vegetation and introduced tropical plants.
This Strangler Fig (Ficus aurea) is the centerpiece of Orchard View Park. This native tree grows around a host tree and eventually kills it. Delray Beach, Florida.
We went to Orchard View Park in early March this year and found an abundance of small wonders.
Curly-tailed Lizard (Leiocpehalus carinatus). This individual does not have a curly tail. Curly-tailed Lizards were introduced into Florida in the 1940s to control insect pests in the sugar cane fields. Delray Beach, Florida.
Resurrection Fern (Polypodium polypoidiodies). This native fern grows on the trunks of trees. When dry the fern turns brown, shrivels up and looks dead. Rain will make it green up and it is resurrected. Delray Beach, Florida.
The Northern Mockingbird (Mimus polyglottos) is the state bird of Florida. Its song is a medley of the songs of other birds. Delray Beach, Florida.
Great Bougainvillea (Bougainvillea spectablis) is native of South America but has been introduced as an ornamental plant to warm regions around the world, including Florida. The flowers are small and white, the large red structures are modified leaves called bracts that play the role of flower petals to attract pollinators. Delray Beach, Florida.
Spinybacked Orbweaver (Gasteracanthera cancriformis). The genus name of this spider is from the ancient Greek and means thorny belly. Delray Beach, Florida.
Lilac Tasselflower (Emilia sonchifolia). This delicate native of Asia is now found in tropical and subtropical areas around the world. Delray Beach, Florida.
Brown Anole (Anolis sageri). Males extend their brightly colored dewlaps and do pushups to attract females. This invasive species from the West Indies has replaced the native Green Anole (Anolis carolinensis) where their ranges overlap, Delray Beach, Florida.

Spanish Needle (Bidens pilosa) is native to tropical and subtropical America. The fruits are dark and rod-shaped with hooked spines on the end. These fruits are hitchhikers that cling to animal fur or people's socks. Delray Beach, Florida.
Pileated Woodpecker (Dryocopus pileatus). This large North American woodpecker is always impressive, from its bold black-and-white pattern to its brilliant red crest. Delray Beach, Florida.
Blue Morning Glory (Ipomeaindica). This vine is native to Florida and tropical America. It has been introduced to other parts of the world and can be invasive. Delray Beach Florida.
White Ibis (Eudocimus albus). These brilliant white wading birds have pink legs, pink face, pink beak and bright blue eyes that give them a startled look. Delray Beach, Florida.
White Ibis. Delray Beach, Florida.
Florida Snow (Richardia grandiflora) is native to South America and when in flower can cover the ground in white. Delray Beach, Florida.
Gray Squirrel (Sciurus carolinensis). This familiar rodent is common in parks across eastern North America and in Orchard View Park too. Delray Beach, Florida.
Oriental False Hawksbeard (Youngia japonica). Originally from Asia it is now a common weed around the world. Delray Beach, Florida.
The Yellow-throated Warbler (Setophaga dominica) breeds in the Eastern United States and winters in South Florida Mexico, Central America and on Caribbean Islands. Delray Beach, Florida.
Asiatic Dayflower (Commelina communis). Like many of the plants in Orchard View Park this one started in Asia is now found in North America and Europe too. Delray Beach Florida.
While Orchard View Park does not boast a beach, or broad views of the Everglades or a dark cypress swamp, it is a peaceful place with a pleasing selection of Florida flora and fauna.
Sandhill Crane (Antigone canadensis). Bosque del Apache National Wildlife Refuge, New Mexico.
Cranes are impressive birds. They are tall, some approached six feet in
height, they perform athletic mating dances and give loud, ringing calls. There are 15 species of cranes world-wide and
are found on all continents except South America and Antarctica.
North America is home to two
species, the more common Sandhill Crane (Antigone canadensis) and the
critically endangered Whooping Crane (Grus americana).

Sandhill Cranes are gray with a red
forehead and a dagger-like beak.They
stand over four feet tall with a six-foot wingspan. During the breeding season Sandhill Cranes will stain their gray feathers brown with iron-rich mud. The reason for this interesting behavior is widely debated by crane experts. One camp says it is a part of a mating display, others think it could be a way to clean the feathers of parasites. Some populations of Sandhill Cranes undertake
long migrations and flocks often fly in V-formations. They are also excellent gliders, riding
thermals in the fashion of hawks and vultures.
Sandhill Cranes breed across much of northern North American and into
eastern Siberia. These cranes make a
migration to the southern tier of the United States and northern Mexico. Non-migratory populations of Sandhill Cranes live
in Florida, Louisiana and Cuba.

Sandhill Cranes are found on
marshes, ponds and prairies. They eat
fish, amphibians, reptiles, birds and small mammals. Sandhill Cranes will also feed on waste grain
in farm fields. The Platte River Valley
in Nebraska is an important stopover on many Sandhill Crane’s northern
migration. They roost in the river and eat
corn left in the fields on their way to Canada and Alaska.

The great American naturalist Aldo
Leopold described the call of the Sandhill Crane as “a pandemonium of trumpets,
rattles, croaks and cries that almost shakes the bog with its nearness…”. Hearing a flock of Sandhill Cranes calling as they
fly from a pond at sunrise is an unforgettable experience.
Whooping Crane (Grus americana). Aransas National Wildlife Refuge, Texas.
Whooping Crane hunting in a marsh. Aransas National Wildlife Refuge, Texas.
Whooping cranes are among the
rarest of North American birds and also a conservation success story. They were probably a rare species before the
arrival of Europeans, but their population crashed in the 19th and
20th centuries from hunting and habitat loss. By the 1930s their entire population was less
than 30 birds. Education and captive
breeding programs have allowed Whooping Crane numbers to increase to over 800
but they remain endangered.
Whooping Crane with Blue Crab (Callinectes sapidus). Aransas National Wildlife Refuge, Texas.
Their loud call gives Whooping
cranes their name. They are white with black
wing tips, black on the face and a red crown. Whooping cranes are even larger
than Sandhill Cranes standing over 5 feet tall with a 7-foot wingspan. The main migratory population breeds in
northern Alberta and the Northwest Territories of Canada. In the fall they fly across the middle of the
North American continent to winter in the coastal marshes of Texas. They spend the winter eating crabs and other
small animals. Several non-migratory populations have been established but high
mortality and lack of breeding success have limited their impact on the overall
population.

Cranes hold a special place in cultures
around the world. In Asia and the
ancient cultures of the Mediterranean cranes symbolized happiness. Cranes were thought to be goddesses in
pre-Islamic Arabia and Aristotle told of fanciful battles between cranes and
pygmies in Africa. In Native American
cultures, cranes often appear on rock art and crane clans are a regular feature
in many tribal groups. Richard Powers,in his 2006 novel Echo Maker describes in moving and vivid detail the
flight of Sandhill Cranes in the Platte River Valley. “More birds land by the
minute, the air red with calls. A neck
stretches long; legs drape behind. Wings
curl forward, the length of a man.
Spread like fingers, primaries tip the bird into the wind’s plane. The blood-red head bows and the wings sweep
together, a cloaked priest giving benediction… They converge on the river at
winter’s end as they have for eons, carpeting the wetlands. In the light,
something saurian still clings to them: the oldest flying things on earth, one
stutter-step away from pterodactyls.”

Looking at plants is good for you. Numerous studies have shown positive changes
in brain activity, neurotransmitter levels and a sense of wellbeing come
from viewing plants. Experiencing plants can reduce blood pressure and lower corticosteroid stress hormones. Our nervous systems resonate with the plant
kingdom. Some researchers speculate this
physiological effect is from overcoming a lack of plants in our human-built
environment. Others posit it is a genetic memory of earlier
times in our history. Whatever the
reason, nature in general and plants in particular are definitely good for
people.
Here are a few of the colors, shapes and patterns of plants
that have caught my eye and soothed my brain.
Leaves
Heliconia sp. leaf. This relative of Banana (Musa sp.) is impressive when light shines through the leaves. San Jose, Costa Rica.
Smooth Sumac (Rhus glabra). These leaves take on a a brilliant red hue in thefall. Rowan County, North Carolina.
Iris sp. leaf. This Iris leaf, with its parallel veins glows in spring. Rowan County, North Carolina.
Bull Thistle (Cirsium vulgare) leaves. The basal rosette of spikey Bull Thistle leaves will give rise to the tall flowering stem. Rowan County, North Carolina.
Stems
Chinese Timber Bamboo (Phyllostaches vivax) stems. This Asian exotic looks at home in the highlands of Costa Rica. San Jose, Costa Rica.
Saguaro (Carnegiea gigantea). The water-storing stems of Saguaro are pleated and lined with rows of spines. Saguaro National Park, Arizona.
Flowers
Buttonbush (Cephalanthus occidentalis) flowers. This cluster of Buttonbush flowers has an unearthly look. Rowan County, North Carolina.
Toad Plant (Eryngium carlinae irazu) flowers. This low growing plant with unearthly blue flowers is found on a few volcanos in Central America. Volcan Irazu, Costa Rica.
Golden Alexander (Zizia aurea) flowers. Golden Alexander is related to Queen Anne's Lace (Daucus carota). Orange County, North Carolina.
Fruits
Old Man's Beard (Clematis drummondii) fruits. These fruits are dispersed on the wind. Patagonia Lake State Park, Arizona.
Texas Ebony (Ebenopsis ebano) fruits). This tree has large woody fruits containing the seeds. Zapata County, Texas.
Stinking Passionflower (Passiflora foetida) fruit. The yellow bracts surrounding the red fruit are coated with a sticky substance that traps and digests insects. Hill Bank Field Station, Belize.
For all the impact of plants on the human psyche,
these structures we find so appealing did not evolve to make us healthy or
happy. Plants have their own agenda of
energy production, water conservation and reproduction. It is an added benefit that these things please
us.

The Outer Banks are a series of barrier islands on the coast
of North Carolina. These islands run for 200
miles and have wide beaches with dunes covered by Sea Oats (Uniola paniculata). The Outer Banks hosts small towns, innumerable
beach houses, hotels and historic lighthouses.
Some of the barrier islands are conserved by the Pea Island National Wildlife
Refuge and Cape Hatteras National Seashore.
Summer is the high season with vacationers from around the world taking
advantage of the beaches and sun. But
winter has its own charms. Fewer people
and abundant birdlife are a couple of draws in the colder months.
We have been making winter visits to the Outer Banks and wild areas on the mainland behind the Banks for many years. Here are some recent experiences there.

Sunrise over the Atlantic is an inspiring way to start a day
on the Outer Banks.The beach can be
quite peaceful, and an ebbing tide leaves ripples in the sand.

Horned Grebe (Podiceps auritus). Nags Head, North Carolina.
Red-throated Loon (Gavia stellata). Nags Head, North Carolina.
Fishing piers, like Jennette’s in Nags Head, get you out over
the water for close-up views of sea life.
On a recent trip a Horned Grebe (Podiceps auritus) was fishing near the pier, and a
Red-throated Loon (Gavia stellata) was flapping.
Double-crested Cormorants (Nannopterum auritum). Nags Head, North Carolina.
Male Boat-tailed Grackle (Quiscalus major). Nags Head, North Carolina.
Female Boat-tailed Grackle. Nags Head, North Carolina.
Bottlenose Dolphin (Tursiops truncatus). Nags Head, North Carolina.
Northern Gannet (Morus bassanus). Nags Head, North Carolina.
Double-crested Cormorants (Nannopterum auritum) flew past in squadrons and
Boat-tailed Grackles (Quisculus major) perched on the pier rail looking for handouts. A pod of Bottlenose Dolphins Tursiops truncata) was rolling near
the pier and Northern Gannets (Morus bassanus) plunged
for fish.
American Wigeon (Mareca americana). Pea Island National Wildlife Refuge, North Carolina.
Male Northern Shoveler (Spatula clypeata). Pea Island National Wildlife Refuge, North Carolina.
Redheads (Aythya americana). Pea Island National Wildlife Refuge, North Carolina.
The ponds on Pea Island host a multitude of ducks in winter. American Wigeons (Mareca americana) and Northern Shovelers (Spatula clypeata) paddled placidly by and a giant flock of over 5000 Redheads (Aythya americana) stretched all the
way across South Pond.
American Avocets (Recurvirostra americana). Pea Island National Wildlife Refuge, North Carolina.
Sanderlings (Calidris alba). Duck, North Carolina.
Shorebirds are not just found on the beaches. A flock of American Avocets (Recurvirostra americana) loafed on one of the ponds and a batch of Sanderlings (Calidris alba) were on the wrack at the Duck
Boardwalk.
We saw land birds in the dunes and inthe scrub and
fields behind the dunes.
Snow Buntings (Plectrophenax nivalis). Oregon Inlet Life Saving Station, North Carolina.
A couple of winters ago a flock of Snow Buntings (Plectrophenax nivalis) stayed near
the Life Saving Station near Oregon Inlet. These sparrow sized birds breed on
the Arctic tundra of Alaska and Canada. In the breeding season they are bold white and black. In winter their coloration is more subdued with white, black andcreamy brown. We were lucky enough to have them on
our coast for the winter.
Eastern Meadowlark (Sturnella magna) Pea Island National Wildlife Refuge, North Carolina.
Savannah Sparrow (Passerculus sandwichensis). Pea Island National Wildlife Refuge, North Carolina.
Eastern Meadowlarks (Strunella magna) haunt the dikes of Pea Island and
Savannah Sparrows (Passerculus sandwichensis) scratch out a living in the dunes.
Tundra Swans (Cygnus columbianus). Pocosin Lakes National Wildlife Refuge, North Carolina.
Snow Goose (Anser caerulenscens). Pocosin Lakes National Wildlife Refuge, North Carolina.
Northern Pintail (Anas acuta). Alligator River National Wildlife Refuge, North Carolina.
Ruddy Duck (Oxyrua jamaicensis). Alligator River National Wildlife Refuge, North Carolina.
Just inland from the Outer Banks are more National Wildlife Refuges
and they host huge numbers of Tundra Swans (Cygnus columbianus) and Snow Geese (Anser caerulescens). These large, noisy birds flew by and landed in a nearby pond to feed. Ducks are abundant too with Northern Pintails (Anas acuta) being the most common and Ruddy Ducks (Oxyura jamaicensis) swiming in refuge canals.
Ash-throated Flycatcher (Myiarchus cinerascens). Alligator River National Wildlife Refuge, North Carolina.
Ash-throated Flycatchers (Myiarchus cinerascens) are western birds but in some
winters one of these large flycatchers makes a wrong turn and shows up in Eastern North Carolina.
Bald Eagle (Haliaeetus leucocephalus). Alligator River National Wildlife Refuge, North Carolina.
Northern Harrier (Circus hudsonius). Alligator River National Wildlife Refuge, North Carolina.
Barred Owl (Strix varia). Alligator River National Wildlife Refuge, North Carolina.
Tree Swallow (Tachycineta bicolor). Alligator River National Wildlife Refuge, North Carolina.
Raptors like Bald Eagles (Haliaeetus leucocephalus), Northern Harriers (Circus hudsonius) and Barred Owls (Strix varia) are abundant in the refuges. Tiny blue-gree and white Tree Swallows (Tachycineta bicolor) swooped over
the fields scooping up the flying insects of winter.
Sandhill Cranes (Antigone canadensis). Pocosin Lakes National Wildlife Refuge, North Carolina.
This winter a flock of about 35 Sandhill Cranes (Antigone canadensis) have been
staying at Pocosin Lakes National Wildlife Refuge.Eastern North Carolina is off their usual
migration route and seeing them here was a rare treat.These tall, gray birds have a ringing call
and will soon be on their way north to their breeding grounds in northern North
America.

A visit to the Outer Banks is a treat anytime of the
year. But winter has the special
attraction of a slower pace and no crowds.The ducks, geese, swans and other birds of winter are not to be missed.
