Terrible. Which suburb?
City of sydney Ecology report noted the following:
The wildlife rescue organisation Sydney Metropolitan Wildlife Services reported a peregrine falcon in Ultimo - residents also reported them in the CBD - and a red-bellied black snake in the Royal Botanical Gardens, while local residents reported sightings of red-bellied black snakes in Redfern and Glebe.
City of Sydney ecology manager Katherine Oxenham said red-bellied black snakes are unusual in the Sydney LGA. They were reported by residents along heavy and light rail corridors in Redfern, Glebe and Pyrmont where there was still some of their preferred moist, long grassy habitat. While these could be from remnant populations, they could also have hitched a ride into the city on a train or a truck, she said.
