It's just a regular day and you're killing some time working in your shed when you hear a banging noise coming from the side of the house. Noisy neighbour? Intruder? If you're in Australia, it's probably a five-foot goanna lizard drumming on the drainpipe with its tail.
That's pretty much what happened to long-time New South Wales local Eric Holland earlier this week when he emerged from his shed to find a supersized lace goanna (Varanus varius) in his backyard. (Despite the shock, he managed to grab a camera and get a shot of the visitor.)
“I was just doing a repair job in my shed when I opened the door and I saw this huge thing run across the ground and out of sight,” Holland tells The Border Mail.
“I went inside after I saw it in the backyard and heard a banging noise coming from the side of the house. When I went outside I saw him on the side of the house with his tail hitting the drain pipe,” he adds.
Goannas (better known as monitor lizards) belong to the family Varanidae, which also includes the world's largest living lizard, the Komodo dragon. They can grow as long as two metres (over 6.8ft) and the largest adults can weigh as much as 20 kilograms (44lbs). They're also well known for their appetite for eggs.
As for Holland's uninvited guest, local wildlife officials have said it's not unusual to spot the reptiles in this part of New South Wales. But the goanna kept its visit short and has not been seen since.
