ONE Wollongbar man has taken the decline of kookaburras into his own hands by installing a nesting box in a tree near his home.
In their spare time, Jakob Pfaeffli and his wife love to play their part in protecting the laughing kookaburra.
"We had a box in our backyard in Lismore and we raised about 15 kookaburras over 10 years or so," Mr Pfaeffli said.
"It's good fun to watch them."
Mr Pfaeffli hopes to see kookaburra numbers improve.
"Kookaburras are in decline ... they've declined about 40% along the east coast and they think it's because of habitat loss," he said.
"This was a green paddock five years ago ... they nest in hollow logs in trees so if you cut down trees there's less and less chance for them to do it."
Mr Pfaeffli and Tree Lopper Pete Bedford installed the nesting box on Wednesday with the aim of attracting a kookaburra pair.
"I think they'll be onto it pretty quick," Mr Pfaeffli said.
"It's about the start of their laying season, so it might just be right for them to lay eggs."
Jan Olley from Byron Bird Buddies said there are steps the community can take to help the bird's population.
"People can help by identifying trees in their properties that kookaburras would nest in," she said.
"A lot of them nest in old ant nests in gum trees, or in hollows, so if you have those on your property they need to be conserved."
She also said to avoid using poisons to get rid of rats and insects in order to avoid a kookaburra ingesting the poisoned pest as a meal.
DID YOU KNOW ...
- Kookaburras are loyal to their family and will have only one partner in their lifetime.
- They laugh to keep other kookaburras out of their territory.
- Kookaburras rarely drink because they get most of their moisture from the blood of their prey.
