All but one of the group was of the same species. Can you tell how many marsh sandpipers there are and can you also spot the lone curlew sandpiper?
This number of marsh sandpipers seems to be a recent record as they have not been recently seen at SBWR in such numbers.
The curlew sandpiper can also be considered a rare visitor now as it is difficult to spot especially at a distance.
These birds used to be more common and in much greater numbers about a decade or more earlier.
Seeing the lone curlew sandpiper at SBWR in 2018 is indeed a rare opportunity.
