Bird was ordained as a priest on 17 May 1975 and appointed Bishop of Ballarat on 1 August 2012.[2]
In January 2016, Bird became the first bishop in Australia to publicly join a global movement showing support for clergy child sex abuse victims by tying bright coloured ribbons to the Loud Fence outside St Patrick's Cathedral, Ballarat. Bird said that "If there is just silence between two people, then one doesn’t know what the other is thinking" and that "This gesture is a way to recognise the suffering and publicly show support to victims, survivors and their families."[3]
In 2016, Bird announced that the estate of a former Bishop of Ballarat, Ronald Mulkearns, which had been left to the diocese, would be set aside to help victims of child sexual abuse committed by priests in the diocese. As bishop, Mulkearns had facilitated moving the priests to different parishes.[4]
In August 2019, Bird acknowledged former Melbourne bishop George Pell's ties to the Ballarat diocese and also apologised for the history of sex abuse in the diocese.[5]
