About This Blog

I guess I should include a brief description of the purpose of my Frog Blog.

I am interested in capturing, identifying and disseminating recordings of frog calls from around where I live (San Antonio, Texas) and from where ever I travel.  

The species I have recorded are listed on the right hand column.  I have them sorted alphabetically by genus name, but have added their common names as well for those who might be more comfortable with those names.  The common names are written "backwards" to make them easier to sort on the list.  So the Cane Toad is listed as Toad - Cane right next to the (unrelated) Toad - Couch's Spadefoot.  Some taxa ended up on the list under two common names.  The Spring Peeper (Pseudacris crucifer) is listed as Peeper - Spring and Frog - Spring Peeper.

Rather than have a single post per species, I have found it easier to just post new posts about the same species when I have something to add, so you will see multiple posts including a particular species.  If you click that link, it will bring you to all the posts that include that species.

I also have a few "groups" of posts about frogs from Texas, Costa Rica, Australia and some groupings comparing frogs that are similar looking or sounding for comparison ("confusing species").   

---------------------------------------------

There are commercial recordings of frog calls available for many areas of the world and a variety of sites where they can be heard online, however getting free access to recordings that you can download and save for use in the field is a bit more challenging.

So I decided to make my recordings available to anyone who wishes to use them for non-commercial purposes under the guidelines of the creative commons license.


Creative Commons License

This work is licensed under a Creative Commons Attribution 4.0 International License and all rights are reserved under that license. All of the recordings included in this site were recorded by Chris Harrison and remain his intellectual property even after they are downloaded.

This means you can
  • download them to your phone or portable player for taking with you in the field.
  • download them to your computer to help you learn your frog calls.
I also strongly support their educational use so you can feel free to
  • use them in non-commercial presentations.   I do expect attribution/credit for any use such as this.  You can just mention where you got the recordings or my name on the last slide, etc..
  • use them for educational presentation or other educational uses.  If you have a permanent educational display in a museum, etc.,  and want the recordings to play to your guests, feel free.
  • If you are getting paid or receiving an honorarium for a presentation, that isn't non-commercial.  You would need to contact me for specific permission in that case.
What you can not do with them would include:
  • copy them to a CD and sell that to others
  • include them in any commercial recording, either as is or "sampled" and altered.
  • any other use which violates the principles of the license under which I have distributed them.
---------------------------------------------

In order to make them easily available, I sometimes put a direct link to the mp3 after the recordings.  Depending on your browser you can right click and choose "Save As" or just click it and it will open in a new window where you can save it. 
I have stopped doing that in more recent posts because in up to date browsers (I tested IE 11, Chrome), you can right click on the audio player icon (the "play" icon) and it will give you the option to save the recording, copy the URL or open in a new tab.  You can then either save it directly or open it in a new tab and save the recording from that tab by going to the "Save Page As" option on the menu bar.  (NB - I have tried it recently in MS Edge and it doesn't appear to work - working on a solution).

  1. Hi! I was wondering what is the name of the program you are using to look at the spectrograms?

    thank you!

    1. I use a free program called Audacity. It is an excellent cross-platform sound editor.

      I have some information about using Audacity in this web post -
