Gang Gangs versus Galah

7 Gang Gangs landed in the tree near the bird bath to come in for a drink, there was a Galah eating grass roots nearby and wasn't happy to share the birdbath with them. The juvenile Gang Gang challenged it and then they had a dispute. The Galah took off and the gang Gangs continued their drink the juvenile was not hurt by the tussle with the Galah. I was watching this as well as the wildlife camera recording it.
