Welcome to skullsite

Skullsite is undergoing a complete makeover. Content is still being added from the old site so if you can’t find any information you are looking for, bear with us as we fully load the site.



Almost 1600 species of birds are present in the database, use the search form at the bottom of this page to look for species you are interested in, or go to the order and family overview to browse the photo’s.

We are grateful to several museums that provided us with photographs of extinct species or allowed us to take pictures of different skulls in their collections.

The dodo (Raphus cucullatus) is extinct since the second half of the 17th century. The dodo pictures show the only intact skull in existence (still covered with skin on one side), which was taken from the last surviving mounted specimen. Many thanks to the Oxford University Museum of Natural History for providing us with these pictures. View the dodo and other extinct species.

This site offers a large amount of information on bird skulls and anatomy, displaying species from all over the world.

No bird has been killed to get its skull or skeleton for this collection. All wild birds died of natural causes or accidental, and in a few cases due to legal hunting by others, or died in captivity. The Experimental Zoology Group of Wageningen University has been authorized by the Dutch authorities to own protected European birds after their death. The permit nr is: FEF 27/06/2/98/0051. The Wageningen University also has a CITES exemption, nr NL004.
Who wants to keep (part of) a found bird should inform oneself about the local laws on bird protection.
