Here's one for Nancy (if she's back from her global perambulations) - no fewer that 16 new species frog discovered on a single expedition (not on Lamma, unfortunately, but my old stamping ground PNG)

It is that time of the year again. Here are two male paddy frogs in a pond at Tai Peng; the upper one seems to be a bit confused.

And the Asiatic painted frog, with the lovely bellow that drives everyone nuts (except this one is a female so she doesn't bellow).

Thanks Tulip. I promised someone (Zep, I believe) awhile back that I would put all six species up so here they are.

Fantastic, Nancy the Frog Lady! Great photos and the complete set! Your prize is in the mail.

For some of us who can't tell the difference could you briefly explain how to tell a Romer's from the ornate pygmy frog?

Really fantastic, completing this set of frog pictures makes you really deserve your official Lamma title now, dear Nancy the Frog Lady!

So, the 6 frog species found on Lamma are:

Brown tree frog (Polypedates megacephalus)
...

Zep, which sound samples are we still missing an you could you get them, please? :)

I think Nancy has the complete set of sound files too and is just working out how to attach them to the photos

There were old records of a 7th species, Gunther's frog (Rana guentheri), on Lamma near Sok Kwu Wan, but despite zillions of nights out in the past three years I have never encountered it here. Lo and behold, on Monday I heard about eight males calling from the ditches in the small farm on the way to PS beach. Now, how these highly aquatic frogs (8 of them) got over that high dry mountain from Sok Kwu Wan is beyond me. I suspect they may have been released as they have never been heard in that farm before. Regardless, we officially have 7 species on Lamma.

The call sounds like the single bark of a small dog. You may hear it in that farm day or night.

Attached is a picture I took of one in Tai Po Kau; I will get an authentic photo of a Lamma frog as soon as I can. If the farmer catches me, someone bail me out of the police box.

I am guessing that no one else wants this title so I will accept it. In one way, I am glad Spicy Island closed (only one way). It was horrifying trying to pass by there on my way home late in the evening. Invariably, some beloved drunkard would shriek out, "It's Nancy the Frog Lady" at the top of his/her lungs, at which the whole place would turn and stare at me, most of them having no idea what was going on.

I will look for that prize.

It takes a bit of practice but the best way to tell the differences is by body shape. The ornate pygmy frog looks triangular if you look down on them from above, whereas Romer's has the more typical frog shape. Ornate pygmy frogs, along with many others in their family (Microhylidae) specialize on termites and ants. Having a body that ends in a point, with a small mouth, probably makes it easier to feed on small things. Sometimes you can see them, and their close relative the Asiatic painted frog (the bellower), at the entrance to a termite's nest getting each one as they come out of the hole.

Romer's tree frogs probably eat any insect they can fit into their mouths, so having a wider mouth is probably a benefit.

You can also note the wavy pattern - dark brown edged in a lighter almost orangish brown on the back of the ornate pygmy frog. Romer's has either a black X on its back or some dark splotching.

The frogs were thoroughly enjoying themselves (as was I) with the few warm, humid days we had, now all is quiet on the Eastern front again. Here is a male brown tree frog that was leaping from branch to branch in a banana tree the other night, seemingly defending it from another male that kept trying to approach.

This frog was crossing my path in Sha Po Old Village, when we were returning returning home at night. As I had only a pocket camera with me, this was the best shot I could get as it just couldn't focus in the dark. The frog (Asiatic Painted Frog or Asian Common Toad, more likely?) was happy to sit patiently and model for me, even in close-up and even though I flashed it several times.

Seeing the poor quality of my night shots, your title, dear Nancy, is safe and nobody will call me L-G the Frogman anytime soon.
Are the "beloved drunkards", now outside Mr Kebab instead of the old Spicy Island, still calling out to you when you walk home from work late at night?

Nice pics. Glad to know some creatures enjoy that horrible humidity!

Yes, that is the Asian common toad. They are poisonous (if you eat them but okay to touch) so they have no fear. Their only enemy is the cobra which is not affected by the toxins.

The beloved drunkards didn't seem to take to Mr. Kebab but have now set up shop at the Beer Garden. It is easier to scurry by the Beer Garden than it was to get past Spicy Island unnoticed.

I mentioned on March 19 that I had heard Gunther's frog in the farm by PS Beach, and that it had only previously been reported in Sok Kwu Wan. I heard it in the farm in Yung Shue Long Valley for the first time on Friday night, April 30. Now tonight I am hearing it for the first time in the swamp near the Tai Peng Community Garden. They must have taken advantage of that big rain and made their move.

Gunther's frog sounds a bit like a dog barking with a one or two note call that is quite different from any others on Lamma. It often calls during the day but can most reliably be heard after dark.
