Mostly, Rufous-crowned Sparrow (formerly known as European Bison Man until he forgot his password) works with bird articles. As a birder, he is fascinated by all of the species abroad that he is likely never to see.

So far, he has started forty-three pages of varying quality: Gallirallus, New Caledonian Rail, New Caledonian Lorikeet, New Caledonian Owlet-nightjar, Beck's Petrel, Horned Parakeet, Crow Honeyeater, Azure-rumped Tanager, Guadalupe Junco, Thick-billed Parrot, Maroon-fronted Parrot, Stripe-cheeked Woodpecker, Coiba Spinetail, Nino Konis Santana National Park, Attmore-Oliver House, Poecile, Fan-tailed Warbler, Pariente's Fork-marked Lemur, Columbina, Claravis, Lava Heron, Red and White Bundle, Titanohierax borrasi, Gunnison Sage-Grouse, Daniel Alomía Robles, Humphrey-Parkes terminology‎, Swallowtail Shiner, Sand Shiner, pecten, uncinate processes of ribs, Rallicola extinctus, List of North Carolina birds, Phyllophaga nebulosa, Sansevieria cylindrica, Strophomenida, Desmoxytes, Desmoxytoides hasenpuschorum, Polydesmida, Heteropoda dagmarae, Periophthalmodon schlosseri, giant skippers, List of Maryland birds, Appalachian Azure, Christian Jouanin, and Columbicola extinctus.

Outside these and the shiny boxes at the top of the page, Rufous-crowned Sparrow is also particularly proud of his contribution to the Antiguan Racer, Carrikeri Harlequin Frog, and Philippine Eagle articles.

He has learned that plans he sets for Wikipedia tend to fail, and if history repeats itself, contributes in short bursts. In 2010 he planned on finalizing Djibouti Francolin for a FAC run while bringing Great Auk and Philippine Eagle up to GA. From there, New World vulture and Labrador Duck would have been targeted while he attempted to update Cape Fear Shiner for a possible FAC. He had decided to dedicate 2009 to improving Wikipedia's articles on the 190 critically endangered species of birds, with an overly ambitious plan to get 52 of them to either GA or FA status by December 31. He failed, but he still is interested in bringing critically endangered articles up to higher statuses. For a page detailing this project, go here. He also wants to start Rododendron vaseyi.
