What up with their chin flub?

[charlamanda]

About a week ago I noticed that some of the larger of my Gray Tree frogs have started inflating their chin flub. There has got to be a name for this...anyone? It is new to me and them and I was wondering what's going on? Is this normal? I have only seen the adults outside do this when they call and so far none of mine have made any noise, much less call. Here are a few pics. Any info would help and make me feel a lot better. Thanks.

This is perfectly normal, and nothing to worry about. I don't own any Gray Treefrogs, but my Pacific Chorus froglets have begun to do this as well. I've even heard some tiny calls coming from a couple of them. Just means your little ones are doing their excercises and you might start hearing some calling in the near future. Congrats!

Looks like you have some vocal sac action going on. They are probably practicing their chorus line so they can attract the females.

Females of most tree frogs use multimodal signals (audible and visual cues) to select their breeding partners. I am sure the males understand these things and want to get an early start.

Thanks, that's a relief. Ah, my little babies are growing up....uh oh, calling? There not going to break out in full chorus mode are they? Yesterday, I found two frogs, one on top of each other, in the pool, the one was flub chin and a great big ?female. There are not going to start this are they?
Here is a pic, forgive my sucky camera!
I put glass marbles in the pool for them to hang on to. I watched one in there one night and he/she kept slidding down the sides, so I put them in so they could hang on and soak comfortably.

Thanks, I hope not too much calling, these guys are loud, loud, loud!!!!

Right now, I have one full grown male Pacific Chorus frog, Yoki, who went into a full blown mating call starting at midnight and lasting for 2 hours Thursday night. It was so loud, it woke up my entire house (and I have two tenants who live downstairs). As if that wasn't bad enough, my Green Treefrog, Rongo, joined in the last half hour and proceeded to drown out Yoki. I say you and I jointly invest in some earplugs!!

Will males call if theres no females around and do they have to be a certain age before calling.... not looking forward to telling the hubby calling might happen. I didnt prepare for that
