It's Springtime and that means one thing for Cuckoo watchers here, the birds migration here.
The New Zealand Migration Cuckoo projects gathers information about two species: the shining cuckoo and the long-tailed cuckoo.
People from around the country note the first time they hear a cuckoo call and record it on a form.
This year some of the cuckoos having been arriving late. To tell us about the project is Michael Anderson, a postdoctoral Fellow in the Evolutionary Ecology Group at Massey University. You can check out the Facebook page here.
