Default What triggers toad/frog croaking?

Our toals and tree frogs are now on full. They start and stop at
interesting times. Does anyone know what triggers them?

We rae wondering if it is temperature? They run for inconsistent lengths of
time and at different times of noght...tho they start as it gets dark.

We will monitor temperature for a while to see.

I think they croak when water and air temperatures reach a certain range.
Why breed if your eggs are going to freeze?
Bullfrogs usually breed when air temperatures are about 77F and water
temperatures are between 68F and 89F.
I know mine usually started courting here in SE WA about the end of June.
Our Junes can be chilly at times.

Thanks for the idea of dual monitoring.

We will begin to monitor both water and air temp....hmmm, slunds like and
indoor/outdoor thermometer might do the trick!

Any thoughts baout why they start and stop at different times in the
evening/night?

Do you mean when they start in spring or when they start and stop in the
course of a few minutes?

Our water temps are in that range, the lower part, but air temps have
yet to reach mid-70s, yet yesterday I saw several bullfrog tads in my
back pond. The grown bullfrogs are sitting on the bank every day but
haven't yet started their deep throating. (calls!)

Were they fairly well developed tadpoles? An inch long as compared to emerging
taddies from the egg?
Bullfrog tadpoles will winter over and then change
the following spring. Again, all temperature (and I'll be food) dependent.
Greenfrog tads will also winter over.
The adult bullfrogs will try and eat their babies both in tad and emerging frog
form. I had thousands of eggs laid and the following year I found one large
taddie.

I am thinking about at night. Sometimes they go on to midnight or more.
Other times they stop after as little as an hour. Reason?

Ah. That's probably weather.

If you were talking about more frequent variations it might have been
threat communications.

Yes, they were just about an inch. no sign of feets, though.

Bullfrog tadpoles will winter over and then change the following
spring. Again, all temperature (and I'll be food) dependent.
Greenfrog tads will also winter over. The adult bullfrogs will try

No kidding? Over winter? I love this group! Always something to learn!

Okay, I'll take a guess. All the male frogs
found their lady loves and once the earth moved
and the stars came out they laid around smoking little cigarettes, just like in
the movies with music, say One Enchanted Evening, playing in the background.

Or maybe a temperature shift, a rain storm is coming, a predator is sniffing
around, the ladies
all have headaches, neighbor cat on the prowl,
they ran out of wine and cheese, the ladies who
showed up are as ugly as frogs.

of the BAND practice this week, you
get a little addled.

Some folks will do anything for their frogs. ) K30, I really think this
sacrifice is not necessary, what would we do without you? ~ jan
