Default Cope Gray Treefrogs(CGT)

Amazing year for CGT's here in Northern NJ. My yard sounds like a South-American jungle tonight with all of the frog activity. Looks like I'll be collecting eggs tomorrow. I began collecting eggs from puddles drying up and hatching them 2 years ago and releasing once they were actively hunting FF's. Maybe my efforts resulted in this years explosion. I found the CGT eggs were mixed with common Eastern toad eggs.

That's so great! Sounds so fun to see them grow and then release them

It's help make my 2 boys(15 & 11) naturalists like me. Both are very comfortable handling reptiles, amphibians, insects(including bumblebees and honeybees) and are the neighborhood snake and snapping turtle whisperers...

It's great to see wildlife thriving here in NJ.

What county are you in? Any chance you could get a recording? I'd be curious to hear it. I'm in Gloucester county and this isn't even considered part of their range... I usually don't hear any chrysoscelis unless I'm down in Cape May County (or out of state in Delaware/Maryland).

I will try tomorrow night. According to sources I've read they extend into Canada. There is a Southern and a Northern sub-species which overlap and probably hybridize. We catch them on our windows from time to time but tonight the number of them calling is tremendous.

How are they as captives? Could be a cool biotope for a viv...

Good question... I never really kept them. We have always just raised the tads and released them once they morphed. I never had the feeder supply I have now. I felt we were increasing their chances of survival if we got them past tad stage.

The two species in New Jersey are 'Eastern' Gray Tree Frog (Hyla versicolor) and the Southern/Cope's Gray Tree Frog (Hyla chrysoscelis).

You can find info in the state field guide. http://www.njfishandwildlife.com/ensp/pdf/frogs.pdf

There's calls of each here:

I'd bet you are actually hearing Eastern Gray Tree Frogs - Hyla versicolor.

Versicolor are very cool frogs with a very interesting call. I remember very loud choruses growing up. Shouldn't be a problem keeping them so long as you are ready with lots of food and a good size viv.

You are correct carola, I have always just referred to them as Cope's Gray Treefrogs since I was 1st introduced when I was young. Old habits...

I haven't heard them nearly as much in the last week but am hoping the showers forecast this week will bring them back out.

I'm tempted to collect a few, or their eggs/tads, and set them up in, yet another, terrarium. Perhaps I will think about it for a few weeks until the opportunity passes. Anyone know NJ's rules on this?

I have both Copes and VA Greys. They are great frogs to keep.
Very active during the early afternoons and if you have more than one male they will call often in spring and fall. Beautiful sound to hear indoors too.

Personality wise, they are extremely bold. When kids visit and they want to hold a salamander, I turn to my largest female Copes and left them hold her instead. They will readily eat from your fingers and often will curl up on you once they find a warm spot.

Great for beginners and kids. They can be spooked of course, and when that happens they are all legs haha~ and they can pee long distance too so do be aware and keep the loaded end pointed away from your face
