KILLER kookaburras are wreaking havoc on their own kind as development encroaches on their homes.
The much-loved native birds are waging a war among themselves in Burua, Beecher and Calliope because their habitat is shrinking.
Evicted from their homes by another species, they are faced with the choice of fighting to the death or moving out.
The ongoing developments within the rural areas are leading to the clearing of land and in turn increasing the birds' aggressive natures.
Burua resident and mother-of-three Ainsley Cambridge said the sound of manic kookaburras was becoming a common occurrence.
"It is the most horrible sound you can imagine," she said. "I would never have thought it was kookaburras until I saw it myself.
"My daughter later found a dead kookaburra lying next to our mailbox covered in blood.
"It was quite gruesome."
A spokesman from the Gladstone and District Wildlife Carer's Association said the species was instinctively territorial.
"Preserving habitats is a big issue with our local population, and has been for a while," she said.
"There also isn't as much food with developments occurring.
"Without assessment it would be difficult to narrow it down to just an issue of habitat, however."
She said it would be interesting to watch local kookaburra populations in coming summer months, the nesting period which typically exposed nasty behaviour.
"It could just be as simple as nature taking care of itself," she said. "Natural disease controls revealing the survival of the fittest."
Developers in the area did not respond to The Observer's requests for comment.
Ms Cambridge said while living in Burua for the past eight years, she could not recall ever witnessing such brutality from kookaburras.
