Third-generation Porangahau landowner Rob McClean is on a mission to track the spread of bellbirds throughout the CHB and the Tararua districts.
"I'm keen to hear from people as to where they are seeing them or hearing them, and when the birds started to return. I think it's important as it will give people an idea of what can happen when you get rid of possums and allow birds to thrive."
Rob has worked with the Hawke's Bay Regional Council on biosecurity for years, but his love of the environment was triggered long before that.
"My father's stories started it all. He was born at Whangaehu in 1925 and he could remember the shearwaters and the cormorants on the cliffs.
"The kiwi were gone by then, but his father - my grandfather - could remember the kiwi running around his hut. He told me he used to compete with wood pigeons for plums. I was brought up hearing bird stories.
