I wish these were under a creative commons license, but luckily I have found a few other sources of wildlife sounds that are. (Wanting to put wildlife sounds in a hobby gamedev project I have going on.) Stuff like this confuses me because they state in their about section that one of their primary purposes is for use in "the arts", but then in the terms of use it says: "Any other uses (including but not limited to commercial, promotional, or administrative uses), reproduction, alteration, modification, public performance or display, uploading or posting onto the internet, transmission, redistribution or any other exploitation of the Website or the Content, whether in whole or in part, are prohibited without prior written permission." That doesn't seem to be very "arts" friendly to me, unless they are liberal in letting people use them for those purposes but simply want to give the permission.
