Waders Watch- Mersing Part 1

Ron Chew had been monitoring and documenting the shorebirds at Mersing for some time now. Mersing Bay turned out to be a stop over for many of the rarer shorebirds during the spring migration. The bonus of seeing them at this time of the year is that many of them are in their breeding plumage.

Early this week, I made my way up there and found two groups of roosting shorebirds. One flock consists of 500 Lesser Sand Plovers, 200 Little Terns, 100 Terek Sandpipers and I was told a few Grey-tailed Tattlers and Common Sandpipers.

Part of the flock of 60 Bar-tailed Godwits. The two flagged Godwits are on the right.

Another cluster has about 400 Lesser Sand Plovers, 60 Bar-tailed Godwits, 30 Grey Plovers, 20 Great Knots, 14 Kentish Plovers, a few Ruddy Turnstones, Common Greenshanks, Common Sandpipers and a Broad-billed Sandpiper.

3 Great Knots, 5 Bar-tailed Godwits, 2 Grey Plover and hidden Terek Sandpiper

Best time to photograph them is during late afternoon with the setting sun behind you. The tide should not be too low or else the waders will be feeding further out.

Last month, Ron reported 200 Terek Sandpipers at Mersing. Now we know where the Tereks gone to.

Managed to find one Broad-billed Sandpiper with  Lesser Sand Plovers.

This Bar-tailed Godwit was flagged in Chongmin-dao on 17 Sept 2014. Shows the importance of places like this for migrating shorebirds.
