Crash Landings (Fallout)

Fallout  –  What does this mean?

Crash landings or ‘fallout’ (term used in scientific literature) of Hutton’s shearwaters occur in and around Kaikoura during the breeding season (September to April) when birds fly from their mountain colonies to the sea. These flights take place at night and birds can become disorientated by the artificial light spill of the Kaikoura settlement which lies within their flight path. Often compounded by poor visibility weather conditions, birds mistake the lights for navigational cues and end up colliding with lamp or power poles and lines or just land prematurely within or around the township instead of the sea, predominantly along Kaikoura’s coastal roads (e.g., Beach Rd and The Esplanade).

From September to February (during egg laying, incubating and chick rearing), what you will find are adult breeding birds which are essential to the survival of their chick. A single parent will not be able to raise a chick alone if the partner has died. Being experienced flyers, crash landings of adult birds usually occur infrequently and in low numbers. Yet, recent events in October 2017 showed that even they can get caught out in considerable numbers under adverse conditions.

The majority of stranded birds you will be finding during March and April (the fledging season). Adult birds will have mostly left Kaikoura by this time, leaving their chicks behind in order for the little ones to lose weight and get ready to fly out themselves for the very first time. It appears that our young birds on their maiden flights are more susceptible to disorientation as we observe much higher numbers of birds crash land during this time.

Once on the ground, birds are unable to take off again. It is as if they cannot make sense of this unusual environment and just remain where they are. Waiting. They will need help to get some water under their feet and some wind under their wings to get going again. As such, they also won’t budge for approaching cars and can end up as roadkill. They also can’t get away from cats or dogs and fall victim to predation. Plus, left alone unattended they will eventually succumb to starvation.

Most birds (except for those dying upon impact) have a good chance to survive if they get rescued, kept safe and released the following day.

Read more about the phenomenon of fallout in Hutton’s shearwaters in our publication on “Investigation of fallout events in Hutton’s shearwaters (Puffinus huttoni) associated with artificial lighting”  Notornis, 2017, Vol. 64: 181-191.



  • Watch out for crash landed Hutton’s shearwater in the streets or on your property and assist in the rescue of these birds.
  • Reduce speed when driving through Kaikoura at night or early morning hours to avoid roadkill.
  • Keep your cats and dogs contained or on a lead at night to prevent predation.
  • Minimise your light spill by
    • directing light sources downwards with hoods or covers;
    • dim or switch off lights where possible;
    • closing curtains at night.



  • Pick up gently with wings contained and place into non-airtight container (e.g. cardboard box) and take the bird to an assigned ‘DROP OFF & RELEASE’ station.

How to pick up a bird?

Approach bird from behind and not up front. Place your hands around the bird so you do contain its wings. You can use a towel to carefully put over bird before you pick it up but remove towel once you placed the bird in a box.


From September – February:

  • Take the bird to Encounter Kaikoura (96 Esplanade, open 7 days 7:30am-6pm) for safe release out at sea.

If you found the bird at night:

  • Keep the bird safe in a dark, dry and cool place, do not feed or water or further handle the bird until release the next day.
  • Please do not attempt to release the bird onto the water at night, as it might become disoriented again.


From March – April (FLYSAFE fledgling rescue campaign):

  • Take the bird to the HUTTON’S HUB on 115 Ludstone Road, Kaikoura.
  • The Hub is open 24/7 and you can drop off a bird anytime.
  • Please use the Hub as the single drop off point!
  • Record your rescue in the ‘Hutton’s Shearwater Rescue Log’ provided at the Hub.

The Hutton’s Hub is a shelter adjacent to the Department of Conservation office; opposite the Kaikoura High School entrance on Ludstone Rd; behind the big DOC shed (follow the signs).


At the Hub you will find wooden boxes (“Hutton’s Hotel”) into which you can place the birds. From here we will examine and safely release birds back to sea.

If all wooden boxes are occupied, please use one of the pet carrier boxes provided in the shelter and place underneath the ‘Hotel’ boxes.

If you are unable to drop off the bird straight away, keep in cardboard box in a cool and dark location; DO NOT water, feed or further handle the bird.

  • Injured birds

We currently have no facility available to tend to injured birds immediately at night and birds will have to be held at the Hub until further examination in the morning. To minimise handling stress to the bird, avoid placing it into the wooden boxes of the “Hutton’s Hotel” and keep in pet carrier box (provided at Hub) or the one you brought the bird in (if appropriately closing to ensure both safety and air flow for the bird), label ‘injured’ (using sticker and marker pen provided at Hub) and place underneath the wooden boxes at the wall.

During business hours you can call or take the bird to Vetcare Kaikoura (03 319 5693) who are kindly offering assessment and potential euthanasia for severe cases free of charge.

  • Dead birds

If not crushed or flattened on the road, you can pick up dead birds and leave at the Hutton’s Hub in the ‘dead bird bin’ next to the Hutton’s Hotel boxes. Please don’t put into wooden boxes which we want to keep free for live birds.

It is advisable to wear gloves or use plastic bag to pick up bird.


Trouble identifying the bird you found?

Please refer to our photo ID guide


Unable to drop off at the Hub?

If you cannot deliver the bird to the Hub, ring the HSCT on 021 0491486 for assistance.


Your Health & Safety

  • Make sure conditions are safe before you pick up a bird from the road.
  • Drivers: be aware of traffic around you when braking or pulling over for a stranded bird.
  • REDUCE SPEED at all times when going through Kaikoura. This is what will keep both you and our birds safe!
  • Wear gloves or disinfect / wash your hands after handling birds.



The occurrence of fallout in relation to artificial lights has been observed in many bird species. Among seabirds it appears to be particularly apparent in nocturnal species, where birds commute to and from their nesting sites / burrows at night, like the Hutton’ shearwater. Together with researchers from the University of Canterbury, the Trust is working toward understanding the factors which may cause birds to crash land here in Kaikoura. We also try to determine what proportion of the population is actually affected by this and how many birds die per year. Findings from these studies will support the development of mitigation measures (e.g., upgrading existing lighting networks to more seabird friendly applications) in collaboration with Kaikoura District Council.

We will need your help to collect data!

Please report sightings or rescue by filling in logs at the Hub or send an email or photo incl. date, number of birds and location to

During FLYSAFE, we are also trialling a data recording app among our night patrol volunteer teams. If you want to become involved, you can register your interest by emailing


FlySafe Campaign

During fledging season (March to April), when young and unexperienced birds become grounded in and around Kaikoura almost every night in varying numbers, the Hutton’s Shearwater Charitable Trust (HSCT) is promoting an increased awareness programme via the FlySafe campaign to encourage maximum input from the Kaikoura community and visitors, enabling the collection and release of as many crash landed birds as possible. Procedures for rescue and release are as described above.
