Missing location for Spearow?

Question

It can also be found in Celdon City via headbutt and it only said Vermilion, some routes in Johto, and Azalea Town.

There's a thread for location guide improvements: http://pokemondb.net/pokebase/meta/14511/corrections-improvements-to-our-location-guide?show=14511#q14511

Perhaps you could put it there.
