Help Identifying A Noise???

[u/Parking_Clerk_8058]

Hey guys, so I have 2 white’s tree frogs (or dumpy tree frogs) that are between 1.5 to 2 years old. They’re healthy, plump lil guys in a bioactive setup. I’m pretty sure one is a male and the other is a female (since only one ever croaks). It’s not unusual to hear the one croaking at night. Last night though, I heard something I’ve never heard before and I’m trying to figure out if it was the frogs. Around 1 am, I heard a loud sharp noise that sounded like a duck? It wasn’t the typical croaking call, it was a singular sharp quack. It was also EXTREMELY loud. The first time I heard it, it was about 5 quacks. After 10 minutes, I heard it a second time just once. I thought maybe my cat had somehow made the noise but he was laying in the same spot on the couch and looked absolutely bewildered. I checked the frogs and they were facing each other on the ground. I’ve been trying to find info/literature or videos on different types of sounds these frogs can make but I can only find stuff on the regular croaking call. Maybe the male was irritating the female and she was telling him to leave her alone? If anyone has any videos or info on sounds other than the normal mating/territorial call I would highly appreciate it. Honestly, it thoroughly freaked me out last night and I’m just trying to figure this out both to make sure my frogs are okay and to put my mind at rest. TIA

My whites tree frogs croaks sound like quacks especially as he's still learning how to get to croak properly, sometimes they do it if one frog has jumped on a male, the male will squeak to basically say hey don't do that, I'm a male frog!
