I am having difficulty identifying this sandpiper seen at Western Lagoon, Werribee, last week. It was on its own. It was definitely much larger than a Sharp-tailed Sandpiper. After mulling over the multifarious possibilities in the ABG, I am thinking it might be a Wood Sandpiper, or, failing that, a hybrid. Hoping someone can be of assistance. The photo was taken from a distance, so may not have enough detail for definitive identification. I am going back to Werribee tomorrow, so may have another chance of sighting it.
Thanks,
Michael

I am pretty sure it is a Sharpie Michael.  Wood Sandpiper appears a bit smaller than Sharpie and the white underparts are eye-catching.

Many thanks for getting back so quickly, Ian. I had not realised a Wood Sandpiper would be smaller. I will also be looking out for a Pectoral Sandpiper, one being seen at Werribee a couple of days ago, and also, I believe, hard to distinguish from a Sharp-tail.
Cheers,
Michael

Good luck finding the Pectoral Sandpiper.  Might be best to look out for a phalanx of bird nerds armed with scopes.  Getting good pics close to the bird will help ID the Pectoral Sandpiper.  You might also find it useful to look at the pics and comments on the BLP gallery before going in search of the Pectoral SP.

Many thanks, Ian. I will look at the BLP gallery now. An eBirder, Simon Starr, posted 8 close-up photos of the Pectoral Sandpiper he spotted yesterday at T-Section Lagoon, Werribee (https://ebird.org/checklist/S156063719), one of the places I will be visiting tomorrow.

Dear Ian,
I have just looked at the BLP gallery images of Pectoral Sandpipers. I see that they are only rarely seen and photographed, with Simon Pelling's being the only one over the last three years. Chris Young's 2020 one is absolutely perfect while Les George's 2020 gives me an excellent idea of the difference between a Wood Sandpiper and a Pectoral. I see what you meant about the Wood Sandpiper being much smaller. I note across most of the Pectorals the yellow base to the bill, although the amount varies quite a bit. The eBirder sighting yesterday at Werribee seems to have far less yellow in the bill. Anyway, I will certainly be looking keenly for a Pectoral tomorrow. Always exciting to be able to photograph an uncommon bird.
Cheers,
Michael
