Is there an online register of different frog species' sounds that you would recommend?

There is no one good place to go, but

iNaturalist.org has a lot

xeno-canto.org just added frogs, and is probably the best in terms of data and UI

Macaulay library has some

FonoZoo is horribly built but has quite a few

Museum für Naturkunde Berlin's Animal Sound Archive is horribly built but has quite a few

Hope that helps!

Tonight at the Frog Census we heard the unique call of the Victorian Smooth Froglet!

Their special call has two parts! Waaaaaarrk Pip Pip Pip Pip Pip!

The “Waaaaarrk” is territorial to warn other males away and the “Pip Pip Pip Pip” is to attract the ladies!

He's right behind us! Sleep tight.

Hanging out tonight with @briar-rosette at a very large mid Missouri pond. Happy Frog Friday.

Boreal Chorus Frog (Pseudacris maculata)

Today’s post is dedicated to the chorus frogs, of which there are many. Due to the amount of different species in the US (12 in total not including Spring Peepers) I decided to split them up based on appearance and similarity of call.

We begin with the Boreal Chorus Frog today as it is the most widespread of the 3 species we’ll discuss. It can be found as far north as the Northwestern Territories in Canada, as far south as New Mexico and North Texas, as far west as Idaho, and as far east as New Hampshire. This range is the main aspect that defines it as it sounds and looks almost identical to 2 other species of chorus frog.

Two of the other more common species of chorus frog are the Western Chorus Frog (Pseudacris triserium) and the Upland Chorus Frog (Pseudacris ferarium). These two species physically have the same tan backs, pale underbellies, and dark streaking that the Boreal Chorus Frog has along with the same distinctive dark eye mask that most chorus frogs possess.

Auditory-wise all three sound identical with a trill similar to the sound of someone pulling back the bristles of a comb. When in groups it can almost sound like bells which often gets them mistaken for Spring Peepers (Pseudacris crucifer). This is why, similar to the situation with cricket frogs, your location at the time of observation is really important when identifying these species.

The Western Chorus Frog, contrary to its name, has the most east range of these species. While it used to be thought to extend well into the lower midwest and some of the Great Plains region, those populations were discovered to actually be Boreal Chorus Frogs. Now this species is known to mostly occupy Michigan, Indiana, and Ohio with some populations in northern Kentucky, eastern Illinois, and western Pennsylvania.

On the other hand the Upland Chorus Frog is found pretty exclusively in the southeastern US extending from west Texas to New Jersey. There is some overlap of course amongst all of these such as southern Indiana and Pennsylvania for crossover between the upland and western species, and southern Missouri for the boreal and upland species, but for the most part location will narrow down which species you’ve found.
