Hi Wikipedia. I am interested in birds, particularly large extinct ones and try to add any information to them that I know. Apologies for any mistake.

My favorite kind of birds are waterfowl, rails (the family), and ratites

Extinct bird work:

–––––––––––––––

Articles Created:

Namornis

Struthio oldawayi

Tsondabornis

Articles Expanded a lot:

Pachystruthio

Struthio anderssoni

–––––––––––––––

Current Project:

- Nothing in particular

I was counting previous edits so this may be slightly off:

[edit]

Mass added to 27 species (last updated August 3 2026)

Wingspan (or height for flightless) added to 20 species (last updated July 30 2026)

Egg dimensions and/or mass added to 73 species (last updated August 4 2026)
