'Disgusting move'
Battling for the lead ahead of the final lap, Bird had bumped into the back of race leader Andre Lotterer, resulting in the Techeetah driver suffering a puncture.
With Lotterer out of the race, Bird was able to storm to what he thought was his second win of the season.
"I tried to go down the inside and Andre [Lotterer] late defended," Bird said when asked about the contact. "It's a big shame and my heart goes out to him."
Lotterer was far less diplomatic about the manner in which his race ended, branding the move "disgusting."
"If they let that go, I don't know what we're doing out there. I don't know what I could have done different," he said after the race, still visibly angry.
"The race was fair up until that point but that's what you call a disgusting move. It's not really the way we should race. I lost it thanks to him."
