CONFUSING SPARROWS IN SALTMARSHES

Sharp-tailed Sparrows have recently been split into two species, because of evidence that two distinct populations meet but apparently do not interbreed on the coast of Maine. . . .

  • Saltmarsh Sharp-tails (labeled "typical" on page 289 in Peterson) nest from the northeastern corner of NC to Maine

  • Nelson's Sharp-tails nest from Maine northward (labeled "maritime" in Peterson) and in marshes of the northern Great Plains (labeled "inland" in Peterson)
The Nelson's Sharp-tails that we saw looked like the ones labeled "inland" -- from the northern Great Plains.   The Saltmarsh Sharp-tails looked like the ones labeled "typical" -- from the mid-Atlantic states.

The closely related Seaside Sparrow nests in saltmarshes all along the Atlantic coast -- including the entire NC coast.


OTHER THAN BIRDS . . .

VERTEBRATES: Gray Squirrel, Bottlenose Dolphin, Six-lined Racerunner (Cnemidophorus sexlineatus), Eastern Spadefoot (Scaphiopus holbrooki), Southern Cricket Frog (Acris gryllus)

CARNIVOROUS PLANTS IN LONGLEAF-PINE SAVANNAS: Purple Pitcherplant (Sarracenia purpurea), Yellow Pitcherplant (S. flava), Violet Butterwort (Pinguicula caerulea/pumila), Yellow Butterwort (P. lutea), Sundew species (Drosera species), Venus' Flytrap (Dionaea muscipula)

OTHER FLOWERS IN LONGLEAF-PINE SAVANNAS OF GREEN SWAMP: Blue-eyed Grass (Sisyrinchium species, Iris Family), Yellow-eyed Grass (Xyris species), Dwarf Azalea (Rhododendron atlanticum, nearly prostrate shrub with white flowers superficially resembling Japanese honeysuckle!)


HIGHLIGHTS

Despite getting caught by a thunderstorm as we finished putting up our tents at Carolina Beach State Park, we otherwise had spectacular weather.   No sooner was the rain over than we saw a male Summer Tanager and then Painted Buntings.   At dusk we heard Chuck-will's-widows and the next morning had great looks at a male Rose-breasted Grosbeak.   For me, the dawn songs of the Great Crested Flycatcher were also a show.

We cleaned up on terns -- including lots of Royal Terns carrying fish (probably males courting mates) and Gull-billed Terns swooping to catch fiddler crabs (talk about an angel of death for the crabs!). Sandpipers and their relatives allowed lots of comparisons of leg and beak lengths.

The intrepid people who thrashed around in the saltmarshes managed to see (actually see!) a rail.   Those who persisted eventually got great looks at both Nelson's and Saltmarsh Sharp-tailed Sparrows.

There were lots of migrant shorebirds -- all the sandpipers and plovers and relatives (except the Oystercatchers and Willets) were headed north, most of them to the Canadian taiga or Arctic tundra.   The Merlin was accompanying them!

In comparison to February, the gulls had almost completely changed guard.   Thousands of Laughing Gulls replaced the thousands of Ring-billed Gulls.   All the remaining Ring-billed, Herring, and Greater Black-backed Gulls (those that had not yet returned to the Great Lakes and New England) were young birds finishing their first winter.

In contrast, we found few migrant landbirds -- the Rose-breasted Grosbeak, the Blackpoll, Yellow-rumped, and Yellow Warblers -- and most of the sparrows.

The Green Swamp was the big surprise.   We found Bachman's Sparrow and heard its haunting songs, and we found the cavity trees of Red-cockaded Woodpeckers (although we could not find the birds), but the flowers were the surprise.   Before we were through we had found five species of carnivorous plants (not counting the Venus' Flytraps at Carolina Beach State Park).

The longleaf-pine/wiregrass savanna was a sight to behold -- sunny tan waves of grass with freckles of violet and yellow butterworts and eruptions of dark chestnut pitcherplants!
