‘PEEP SHOW’: WHITE-RUMPED SANDPIPERS ON ABACO

The White-rumped Sandpiper Calidris fuscicollis is one of a number of sandpiper species found on Abaco. You can see a gallery HERE. Many of them are confusingly similar, and it is with a sense of relief that one picks out some particular feature on a bird that marks it out from the other species.

The white-rumped sandpiper has, for a start, a white patch that shows above the base of the tail, rather in the manner of the yellow-rumped warbler. It is the only sandpiper with such a feature, and it is conclusive of ID… if you actually see it. You’ll notice that in the header image and the one above, no such white patch is visible. So although it is undoubtedly there, the bird you happen to be looking at – perhaps at a distance – may not have arranged its position and feathers to assist you. Frankly, the birds in the WRS group below are not cooperating either, except the furthest (blurry) one.

You can’t see it on this bird either, as it forages in a pond, spreading concentric circles across the water

Nor with this one. In fact, I have looked at dozens of photos to find a clear shot of said white marking and found only one really good one… but hedged around by the thick thorny protection of copyright.

However all is not lost. There is another feature of this sandpiper species that is unique to it, at least on Abaco (it is found also in the Baird’s sandpiper, but you won’t see that bird on the island). The unusually long wings of the white-rumped sandpiper extend beyond its tail when it is on the ground. You can see this in the photos above. It is a feature that should be clearly visible as you watch a bird on the shore, even if it isn’t showing its white rump. Here’s a very helpful composite from the Crossley ID Guide (Eastern Birds). You can see the extended wing length in the birds in the foreground. And if you look at the birds in flight, you will see the white rump exposed.

Like all peeps, these birds make high-pitched weebling sounds, which I have seen described as ‘like a child’s squeaky toy’. Here’s a small flock make a characteristic noise.

You will often see a WRS mixed up in a group of other shorebirds, so the wing-length ID method will help pick it out. Also, it will be notably larger than some, for example semipalmated sandpipers. White-rumped Sandpiper + 2 semi-palmated(Woody Bracey)1

WORLD SHOREBIRDS DAY: ABACO’S 33 SHOREBIRD SPECIES (2)

Yesterday I featured 8 of the larger, longer-billed species among Abaco’s 33 shorebirds. Plus one cute Wilson’s Plover chick as page-bait! A number of those are classified as sandpipers. To see them, click HERE. Today it’s the turn of the smaller sandpiper species, little birds with long beaks for their size that in general help differentiate them from the stubby-beaked plover species. To recap, here is the main Abaco shorebird checklist of 26 species (birds previously featured in bold):

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).

SANDPIPERS

Of the sandpiper species shown below, 9 of the 10 are ones that, at the right time and in the right place, you may see on Abaco. The tenth, the Wilson’s Phalarope, is the first specimen ever recorded for Abaco and as far as is known this is the only photo of it (props to Woody Bracey for this accomplished ‘get’). Again, some of the birds shown below were photographed on the Delphi Club beach.
