Migratory ducks tend to arrive on La Palma later in the year than waders. There have been several interesting species on the island this autumn.
I assume the above bird is a Eurasian (Anas penelope), rather than an American (A. americana) Wigeon, simply because of the reddish-brown tones on the head and neck. First seen on Nov 25, the bird is still on the island.
There have also been up to 18 Common Teal (Anas crecca) in Las Martelas in recent weeks, and, at the seawater pools near the airport, the juvenile Bar-tailed Godwit (Limosa lapponica) was discovered on Nov 18, later to be joined by a second bird. Both are still present at the time of writing.
