What kind of tree frog croaks in the day?

This is the only semi decent picture I have of Frodo and his puffed out chin flub while calling...

That looks cool.

During my fake rainy season I'll get a random daytime chirp every now and then from one of my boys. Maybe he's just your only boy and he's letting the girls know a stud lives next door. I think that's my boy's way of saying there's going to be action tonight.

<---that's Waldo, Gray Tree Frog, in my avatar singing at 7pm with all the lights on with no encouragement besides me and the cats as a captive audience. He not only sings whenever he likes, he's not at all shy about it

He's also pretty reliable at singing when I mist the cage, maybe 50/50, as he's doing in the attached photo at 2pm. Spontaneous afternoon and morning calling occurs as well, especially when it's raining outside, but it happens at any time and in any weather.

Grays in the wild will also call at any time. Much more frequently in the late evening and during rainy times, but it happens all the time.
