Frogs night-out in the swamp (lots of photos)

Postby tropicbreeze » Sat Jan 03, 2015 11:18 pm

Last night saw a lot of raucus behaviour in the swamp on my place. The rains had finally set in and water was piling up. Come nightfall and the frogs erupted in a deafening cacophony of sounds. Spent quite a few hours out there with the camera. The grasses still haven't had time to grow up so a lot of the swamp was open and easy to get through. So I was up late into the night and spent a lot of today sorting out and cropping/resizing most of the couple of hundred photos taken. Not all were of frogs though. I narrowed the frog ones down to 57 but won't post that many now. Haven't had time to check all the IDs.

Anyway, here they are, generally in order they were taken and not grouped together. They're numbered for easier reference. (Not sure how this will work out with so many photos on the one post.)

Looks like a great night, makes me excited for next week - especially seeing all those pairs in amplexus. Did you need help with any of the ID's in particular?

Yes, the rain's become quite reasonable and is persisting. They were out in force again last night but I didn't go out. Tonight I did venture out for a short while. Only new one I found was Crinia bilingua. Surprisingly didn't see any Giant Frogs nor Marbled Frogs. The Giants were out before the rains came, quite common in fact. The Marbled are usually fairly common but not a sign.

Help with IDs would be good thanks. This is what I've managed so far.

Number 28 is an interesting one, I would say based on the uniform dorsal pattern they are Litoria tornieri in amplexus. Interesting observation with the crab, I wonder how common it is for them to eat frog spawn.

Thanks for those IDs. Is it Platypectrum now for the Ornate? On 28 I'm not game to say. Had second thoughts about calling it L. pallida but then was less sure about it being anything else. Those crabs are very common but they don't swim. So with frogs eggs mostly floating up at the surface they wouldn't get to them.

The rains are easing here but ramping up in the Kimberleys. By next week though it should have eased there. But most likely anything not bitumenised will be closed. Still, see how it goes when you arrive.
