Do Brown (whistling) Tree frogs change colour for a reason

[Jess]

I'll have to take pics of mine aswell :P. Last night they were a really dark brown almost black, this morning they're a creamy golden, though like dlord said they go pale at night.

It happens to my Green and Golden Bell frogs too. At night they will be pale almost a glowing gold and in the morning they will go back to their normal dark colouration.

It's really fascinating isn't it? These are my first frogs, so I had no idea that they did that :P. I've learnt a LOT about frogs since I've had my boys, they are really awesome animals!

Yes it is fascinating, I didn't know frogs changed colour based on the light either. I think it might be a camoflouge thing. You should make an album of your frogs

i was wondering why too, and heres some videos of my ewingi tadpoles changing colour, i wonder if its there blood or something this link here: " http://www.frogforum.net/tree-frogs/...html#post71774 "

heres a video of 2 ewingi tadpoles, the dark tadpole has just been taken from its black plastic lined 'aquarium'(small puddle in terrarium really) and placed in a 20 L clear plastic container where you'll see a lighter coloured ewingi tadpole that has been raised in there, not long after an hour or so the dark tadpole became light too
