They have recently published videos of native people giving some vocabulary in four endangered African languages: Punu, Mpongwe, Akele and Benga. The words are about body parts, numbers, colors and common phrases.
I have enabled these languages for editing at OmegaWiki and added all the words mentioned in the videos. By doing so, these translations are not only available to people speaking English, French or Spanish (the three languages of the video), but to all the other languages at OmegaWiki.
We now have 28 expressions in Akele and Benga, 59 in Mpongwe and 78 in Punu.
If you know about more resources (vocabulary) for endangered languages, you are more than welcome to mention them.
