The year at a glance
Lighter bars mean it happens in some years or for some birds.
All year round
- Dogs are the main killers of adult kiwi in Northland. Kiwi of all ages are at risk from dogs all year. Visitors bringing dogs and cats to Northland are a threat.
- Feral cats seem to breed for most of the year in Northland, compared with October breeding further south.
- Chicks are the most vulnerable stage. They need 6 months to reach 1200 g, heavy enough to fight off a stoat.
- Some pairs have 3 clutches a season, so females can be gravid (carrying an egg) and chicks about for much of the year. First hatchings are in late September (reaching 1200 g by March), the last in April (1200 g by October).
- Whangārei birds seem to nest earlier than those further north.
Kiwi can be anywhere, anytime.
