The next major group to be covered on XC is the Frogs and Toads of the world. As a start, we publish a set of recordings from the late 1960s to the end of the 20th century by Marinus Hoogmoed, former curator of herpetology at Naturalis Biodiversity Center, covering over 100 species from South America. His collections and corresponding notebooks at Naturalis have recently been digitised, made possible by NLBIF funding. Among those collections were these nice recordings. In many recordings, Marinus made comments while recording (in Dutch). These can usually be found at the end of the recordings.
The frogs are here!

What is xeno-canto?
xeno-canto is a website dedicated to sharing wildlife sounds from all over the world. Whether you are a research scientist, a birder, or simply curious about a sound that you heard out your kitchen window, we invite you to listen, download, and explore the wildlife sound recordings in the collection.
But xeno-canto is more than just a collection of recordings. It is also a collaborative project. We invite you to share your own recordings, help identify mystery recordings, or share your expertise in the forums. Welcome!

Thanks for noticing. Special appreciation to the eBird team for providing me with training in sound recording and editing. eBird and Idea Wild also provided the audio recording equipment that has made the recordings possible. Look forward to continuing to contribute more sound recordings.
Great to hear all of that Jonathan. Keep recording!
