Report rook sightings in North Canterbury
Environment Canterbury media release; 22nd September 2026
Just when we thought rooks had flown the coop in Waitaha Canterbury, a recent sighting in North Canterbury has biosecurity staff asking the public to keep their eyes and ears open.
A possible rook was reported near Hawarden earlier this month, prompting Canterbury Regional Council (Environment Canterbury) biosecurity officers and contractors to visit the area and investigate.
While it's not yet clear whether the bird was simply passing through or has decided to stick around, one thing is certain: early reports give us the best chance of responding quickly.
Why this sighting matters
Environment Canterbury Biosecurity Officer Rob Kent says community reports are critical to helping locate any remaining birds.
"Rooks are highly intelligent and extremely wary, which means they can be difficult to find and control," says Rob.
"The public plays a vital role in helping us track down any remaining rooks. If you spot a bird that looks or sounds like a rook, report it as soon as possible. The sooner we know about it, the better our chances of locating it and responding effectively."
Rooks are a declared pest in our region. They can cause significant damage to newly sown crops by pulling up seeds and young plants while feeding and can also damage pasture by tearing up the ground in search of insects and grubs.
For decades, Environment Canterbury has worked to completely eradicate rooks from the region. Once numbering in the thousands across parts of Canterbury, these birds are now rarely seen thanks to sustained control efforts and support from local communities. However, ongoing vigilance is needed to stop rooks from re-establishing and undoing years of progress.
What does a rook look like?
Rooks are members of the crow family and can be identified by:
- Glossy black feathers with a purple-blue sheen.
- A pale grey, featherless patch around the base of the beak.
- A distinctive "kaah" call.
- Fluffy feathers on their legs make it look like they are wearing trousers.
- Larger size than a magpie.
Seen one? Let us know immediately.
If you think you've spotted a rook:
- Take a photo if you can do so safely.
- Note the location.
- Call Environment Canterbury on 0800 324 636.
Please don't approach or attempt to shoot the bird. Rooks are highly mobile and can quickly move on if disturbed, making them much harder to locate and control effectively.
Your reports could help us respond quickly and support Canterbury's ongoing rook eradication efforts.
