Frequently Asked Questions

Why should we care about falcons?

The New Zealand falcon is Nationally Threatened. They are rarer than the Kiwi, and despite already being at unacceptably low numbers, their populations are still declining.fern.jpg

What does it mean when something is threatened?

Threatened species are under threat from becoming extinct. The Department of Conservation, in partnerships with top academics from around the country has set a classification scheme for the threat status for each native species. Those that are threatened are a priority for conservation and while they aren’t critically endangered (as some endemic species now are), if their populations continue to decline they will become critically endangered at which point it is very difficult to bring them back from the brink of extinction.

Doesn’t the Department of Conservation (DoC) look after threatened species?

New Zealand has nearly 3000 threatened species and DoC only has funding for 250 of these animals – it is imperative that local communities get behind those native creatures such as the NZ falcon, that do not currently have a conservation program in place

How well can they see?

Falcons have eyesight 8 times better than humans

How fast can they fly?

They can reach speeds of over 200 kphFern flying-.jpg

How big are they?

The males and females are different. The female is close to one third larger than the male: Female falcons weigh around 500 grams and are approximately the size of a magpie; Male falcons weight about 350 grams and are approximately the size of a domestic pigeon

Where do they nest?

On the South Island, Falcons almost always nest on the ground. They create a ‘scrape’ on the ground, usually in the depression underneath a large boulder or under a fallen tree to give them cover from the elements and to protect them from any aerial attacks. While it may seem counterintuitive to make a nest on the ground, we must remember that falcons evolved with other birds of prey (such as the Haast Eagle) as their main predators, so nesting on the ground actually provided more protection from above than nesting in a tree would have. 

How many eggs do they lay?

How long does it take for eggs to hatch?

Eggs hatch after 31 days, with the chicks leaving the nest about a month after hatching. In this time, their parents feed them around 10x per day.



What to chicks look like?

When chicks are born they are totally dependent on their parents for food, warmth and shelter. They can’t even see.

They are born with a fine down that helps to keep them warm. Once they reach about 12 days of age they develop a thick grey down which helps keep them warm so mum can help dad hunt for more food. By the time they are 35 days old, chicks are fully grown and have developed most of their flight feathers.



Aren’t falcons only a high country bird? Why are you releasing them in valleys?

A common misconception about falcons is that they are solely ‘high country animals’. This is not true, without persecution, introduced mammals, electrocution, and habitat destruction, falcons would be found all over NZ.

What do falcons eat?

Falcons are extremely well-adapted to hunting avian prey, but they do sometimes catch mammals (mainly rabbits and mice), reptiles, and insects. Scientific research conducted in Marlborough by Dr. Sara Kross has shown that falcons prefer to hunt for introduced birds and actually select against eating endemic bird species, even when they are available in the surrounding habitat.

How old can they live?

In captivity some falcons have lived for about 15 years. The oldest known wild falcon was a female who lived to be 9 years old.falcon nest.jpg

What noise do they make?

Falcons are normally silent, counting on stealth to hunt for their prey. When they do make noise, it is often in territorial defense- this noise is called ‘Kekking’. Falcon chicks sometimes ‘Whine’ to beg their parents for food. Female falcons also whine to tell males they need more food for the chicks or themselves. Falcons can make a ‘Chittering’ sound which is often heard after copulation or during play.

I saw a raptor in the sky- was it a falcon?

Because falcons are so rare, it’s a good chance that you didn’t see a falcon. Harrier hawks are much more common and tend to hunt by soaring through the air and looking down to spot carrion or easy prey. Falcons, on the other hand, usually hunt from a perch, from which they will swoop down and fly directly at their prey using quick wing beats and looking straight ahead.

Don’t falcons eat native birds? Why would you want to increase their numbers?

Research in Marlborough has actually shown that even though falcons evolved hunting native birds, they actually prefer to eat introduced birds. The vast majority of falcon prey are introduced finches. This may be because endemic birds evolved with falcons as their main predators and therefore have better antipredator behaviours. Or there may be a nutritional explanation.feeding.jpg

We want to increase their numbers because ecosystems cannot function naturally without predators present, and the Falcon is the only endemic bird of prey left in New Zealand (several other species are now extinct). Predators are needed to keep their prey populations in check, and without predators there are often more cases of disease outbreaks and starvation in prey species.

How high can they fly?

We don’t know! We often get this question from children and can’t give them a true answer. We know that we’ve watched falcons fly so high into the sky that even with binoculars they actually disappear from view altogether! 

Do falcons eat roadkill?

Falcons almost NEVER eat carrion. Falcons prefer to eat food that they have caught themselves.

Where are falcons found?

Falcons are found throughout New Zealand in areas South of Auckland. On the South Island, falcons are often described as being a high-country bird because this is where they are most often spotted. However, this term is incorrect. Falcons were found throughout almost all of the habitats in New Zealand prior to human settlement, and have only been driven into the high country because of persecution by humans and the introduction of predatory mammals.

What is the MFT?cat predation.jpg

We are a locally-run Charitable Trust working to increase numbers of Falcons in Marlborough.

Aren’t you just doing this to help the vineyards?

NO! This project is about increasing the numbers of falcons and raising the profile of falcons in the community. We are releasing falcons into territories at the edge of the known range of wild populations in Marlborough. These locations often are vineyards, but not necessarily so. We choose release sites that are the most appropriate for the falcons.
