Sandpipers and yellowlegs
Both on the 16th and 25th of January Ricardo found flocks of shorebirds flying along with ibises, lapwings, stilt. The shorebird flocks were very large with more than 100 individuals. They were mainly composed of pectoral sandpipers with some yellowlegs. Both have yellow legs, but yellowlegs' extend from the tail. The yellowleg has a white rump, where as the pectoral sandpiper's split. It is worth showing both the flock and pinpointing some individuals.
