Burnett Trees was contacted about a peewee that had been snagged on fishing line 40 metres up a Norfolk Island pine and was being attacked by crows, which would most likely have killed the small bird.

They dispatched arborist David Bampton, who scaled the tree and eventually released the bird, which escaped its attackers and flew to safety.

Burnett Trees performed the operation for WIRES free of charge.

"Native animals, in particular small birds and sea life, are unnecessarily injured on a regular basis because of incidents with fishing line, hooks and other litter that can entangle, trap or maim them," WIRES spokesman Justin McKee said.

"It's possible to help prevent these injuries by keeping our marine environments and the surrounding area free of potential hazards by disposing of rubbish thoughtfully and appropriately.

"Birds can become entangled with fishing line quite easily.

"Unfortunately this can lead to severe damage as the bird attempts to free itself, and this in turn can render the bird unable to fly, leaving it vulnerable to predators.

"During 2013, WIRES received over 1700 calls to rescue sea birds alone; 244 of these were Australian pelicans and we also received calls to help 807 sea turtles.

"Large sea creatures like turtles and sea lions, which are not uncommon on parts of the NSW coast, can ingest debris floating around the oceans, which inevitably makes them sick or kills them."
