White-rumped Sandpiper, 2

 White-rumped Sandpiper (Calidris fuscicollis)

I returned to the saltpans in Fuencaliente at about 11 this morning. The Common Shelduck (Tadorna tadorna) was no longer to be seen, but the 2 x White-rumped Sandpipers (Calidris fuscicollis) were still present at the site.

This post shows more images of one of the two sandpipers. The second bird was foraging by itself, along the far side of one of the pools, and the two stayed away from each other during the hour I spent observing.

As commented in my previous post, there is a striking amount of brown on the bird's bill. In my experience of this species to date, the brown had always been restricted to a small area at the base of the lower mandible.

The extremely long primary projection can be appreciated in the image above, and the white rump is also discernible. For size comparison, note the Ruddy Turnstone (Arenaria interpres) top right.

I will probably make another trip to the saltpans this week, in the hope of being able to photograph the two Nearctic waders together. An Atlantic depression is forecast to hit the island by tomorrow, with rain for the next three days. The bad weather could possibly influence the length of the birds' stopover.

In addition to the species featured in the last 3 posts, the following migrants can also be expected at the saltpans, at the time of writing:

1-2 x White Wagtail (Motacilla alba), 1 x Ringed Plover (Charadrius hiaticula), 1 x Little Stint (Calidris minuta), and 1 x Common Sandpiper (Actitis hypoleucos).

At the freshwater irrigation ponds near Los Llanos de Aridane, in addition to the usual small numbers of common waders, other migrants include ca. 15 x Eurasian Teal (Anas crecca) and 5 x Common Coot (Fulica atra).
