WORLD SHOREBIRDS DAY: ABACO’S 33 SHORE SPECIES (1)

Abaco is home to 33 shorebird species. Like the human residents of the main island and cays, some are permanent; some are winter visitors arriving to enjoy a warmer climate; and some a transients (e.g. Delphi Club members). To celebrate today being World Shorebirds Day, I am going to feature Abaco’s quota of the world’s shorebirds in 3 posts over the next few days. I’ll start with the definitive checklist of Abaco’s shorebirds compiled by Bahamas Birding author and authority Tony White  with Woody Bracey especially for the BIRDS OF ABACO. I have kept to the conventional / official species order. I’ve let the formatting run wild, though… problematic in WordPress. I may try to sort it. Or perhaps not…

AMERICAN AVOCET Recurvirostra americana   WR 4
American Avocet, New Providence - Tony Hepburn

The codes will tell you, for any particular bird, when you may see it (P = permanent, WR = winter resident, TR = transient, V = vagrant); whether it breeds (B) on Abaco; and your chance of seeing it, graded from easy (1) to vanishingly unlikely (5).

  • Wilson’s Phalarope                            Phalaropus tricolor                       V 4

Of these 26 birds, 23 are ones you might encounter, though some only if you are lucky or your field-craft is excellent. If you happen upon a Long-billed Dowitcher or an American Avocet, tell someone! And the photo I will be posting of a Wilson’s Phalarope is of the first specimen ever recorded for Abaco. And it so happens that I can illustrate them with photographs, mostly from the book archive… What a coincidence. All except 3 were photographed on Abaco; and I have purposely chosen many that were photographed on the lovely 1-mile curve of white sand watched over by the Delphi Club and historically named ‘Rolling Harbour’.

For the sake of completeness, the other 7 species of shorebird recorded for Abaco – all transients or vagrants – are:

  • Upland Sandpiper                     Bartramia longicauda             TR 4
  • Whimbrel                                    Numenius phaeopus                 TR 4
  • Hudsonian Godwit                   Limosa haemastica                   V5
  • Marbled Godwit                         Limosa fedoa                               V5
  • Buff-breasted Sandpiper          Tryngites subruficollis            V5
  • Pectoral Sandpiper                   Calidris melanotos                    TR 3
  • Stilt Sandpiper                           Calidris himantopus                 TR 3

OK let’s see some of the birds. I’ll post one shot of each of the 26 birds to show them at their best in their perfect environment – wild coastline. Some of these species haven’t yet featured in the blog at all, or else not for a while. Let’s go with some of the larger and / or long-beaked species, including a couple of matching pairs.

LEAST, BUT NOT LAST: THE SMALLEST SANDPIPER

LEAST, BUT NOT LAST: THE SMALLEST SANDPIPER

220px-Status_iucn3.1_LC.svg

The LEAST SANDPIPER (Calidris minutilla) is the smallest shorebird, the definitive “peep”. An adult is only about 6″ long. They are to be found in pairs or groups, busily foraging in the sand and seaweed. Often they will mix in with other shorebirds. These birds nest in scrapes close to the water, with both parents involved in incubating the eggs. The female will usually leave the nest before the young birds fledge – perhaps (bizarrely?) sometimes even before the eggs hatch. Deal with it, male Least Sandpipers. Fortunately the hatchlings can feed themselves very soon, and are able to fly within two weeks of birth.

SEABIRDS, SHOREBIRDS & WADERS: 30 WAYS TO DISTINGUISH THEM 

I have recently been looking at hundreds of photos of birds, many with aquatic or semi-aquatic lives. These can be broadly categorised as seabirds, shorebirds or wading birds. But with some bird breeds, there can be doubt as to which category applies. There is the strict Linnaean ordering of course, but in practice there is a degree of informal category overlap and some variation in the various bird guides. This is especially so between shorebirds and the smaller, less exotic wading birds. Shorebirds may wade, and wading birds may be found on shores. Then I remembered a past blog post by the estimable BEACH CHAIR SCIENTIST that I thought deserved an outing here. I re-blogged the chart from BCS early last year. In the meantime site followers and site hits have surprisingly increased considerably, but I suspect only the dedicated make time to sift through any blog’s archives…  Even if you have no problem distinguishing birds in the 3 categories, there are avian characteristics within each list that are interesting observations in themselves. 

10 CHARACTERISTICS OF SEABIRDS 

Whitetailed Tropicbird WikiPicWhite-tailed Tropicbird

(Examples include albatross, auk, booby, frigatebird, fulmar, gannet, penguin, petrel, puffin, shearwater, and tropicbirds)

1. Seabirds are pelagic, spending most of their lives far out at sea.
2. Seabirds move toward to coastal areas to breed or raise young for a minimal amount of time.
3. Seabirds are light on their undersides and dark on top (an adaptation known as countershading).
4. Seabirds have more feathers than other types of birds for more insulation and waterproofing.
5. Seabirds have flexible webbed feet to help gain traction as they take off for flight from the sea.
6. Some seabirds have unusually sharp claws used to help grasp fish under the water.
7. Some larger seabirds (e.g. albatross) have long, slim wings allowing them to soar for long distances without getting tired.
8. Some smaller seabirds have short wings for maneuvering at the surface of the water.
9. Seabirds have specialized glands to be able to drink the saltwater and excrete salts.
10. Some seabirds (e.g. gannets) have a head shape that is usually tapered for more efficiency in plunge diving.

10 CHARACTERISTICS OF SHOREBIRDS 

Wilson' Plover male Wikipic

Wilson’s Plover

(Examples include avocets, black skimmer, oystercatchers, plover, sandpiper, and stilt)

1. Shorebirds have long legs, pointed beaks, and long pointed wings.
2. Most shorebirds are migratory (Impressively some shorebirds fly non-stop for 3-4 days, equivalent to a human running continuous 4-minute miles for 60 hours).
3. Shorebirds wade close to the shore and poke their bills into the ground in search of food.
4. Shorebirds are small to medium size wading birds.
5. Shorebirds tend to frequent wetlands and marshes and are biological indicators of these environmentally sensitive lands.
6. Shore birds are of the order Charadriiformes.
7. Shorebirds are very well camouflaged for their environment and their appearance may vary from place to place as plumage (feather colors) are gained or lost during breeding.
8. Shorebirds typically range in size from 0.06 to 4.4 pounds.
9. Oystercatchers have a unique triangular bill that is a cross between a knife and a chisel.
10. The black skimmer is the only native bird in North America with its lower mandible larger than the upper mandible, which helps the bird gather fish as it skims the ocean surface.

10 CHARACTERISTICS OF WADING BIRDS 

Great Egret Wikipic
Great Egret

(Examples include crane, egret, flamingo, herons, ibis, rail, spoonbill, and stork)

1. Wading birds are found in freshwater or saltwater on every continent except Antarctica.
2. Wading birds have long, skinny legs and toes which help them keep their balance in wet areas where water currents may be present or muddy ground is unstable. Also, longer legs make it easier for them to search for food (forage) in deeper waters.
3. Wading birds have long bills with pointed or rounded tips (depending on what is more efficient for the types of food the bird consumes).
4. Wading birds have long, flexible necks that can change shape drastically in seconds, an adaptation for proficient hunting.
5. Herons have sophisticated and beautiful plumes during the breeding season, while smaller waders such as rails are much more camouflaged.
6. Wading birds may stand motionless for long periods of time waiting for prey to come within reach.
7. When moving, their steps may be slow and deliberate to not scare prey, and freeze postures are common when these birds feel threatened.
8. Adult wading birds are quiet as an essential tool for hunting. Wading birds may be vocal while nestling or while in flocks together.
9. Many wading birds form communal roosts and breeding rookeries, even mixing flocks of different species of wading birds or waterfowl.
10. Wading birds fully extend their legs to the rear when flying. The neck may be extended or not while in flight, depending on the species.
