White-rumped Sandpiper, 1

 White-rumped Sandpiper (Calidris fuscicollis)

As briefly mentioned in my previous post, two Nearctic waders were present at the saltpans yesterday afternoon (Nov 19), in addition to the Common Shelduck (Tadorna tadorna).

In recent years, the White-rumped Sandpiper (Calidris fuscicollis) has almost become a regular visitor to the island, with birds often arriving in pairs. According to the latest 2018 SOC (Sociedad Ornitológica Canaria) checklist, 12 of the 57 Canary Islands records have been on La Palma, either at the saltpans in Fuencaliente, or at the irrigation ponds in Las Martelas (Los Llanos de Aridane). The present sighting now brings the figure to 13, from a total of 58 records.

The bird shown in the first 3 images was easy to photograph and obligingly raised its wings at regular intervals to reveal its distinctive white rump.

The second bird, shown in the last image below, remained at a greater distance from the pool edges. The extent of pale brown on its bill is partly due to translucence caused by late-afternoon sunlight, but the impression is remarkable nevertheless. Its apparently warmer plumage tones can also be attributed to the effect of lighting.

This record will be submitted to the Spanish Rarities Committee in due course.
