Source: Webster's dictionaryAs late as the 1930s, a caged throstle was placed beside the touchline during matches and it was said that it only used to sing if Albion were winning. Source: Internet
In the mid-1970s, a more abstract version of the throstle was used on the club's shirts, while in the late 1970s through to the mid-1980s, an embroidered WBA logo was displayed, a common abbreviation of the club's name in print. Source: Internet
The throstle was chosen because the public house in which the team used to change kept a pet thrush in a cage. Source: Internet
