In 2004 the authorities killed almost 60% of an already endangered resident dotterel population with brodifacoum poison

Bill Benfield writes in his book The Third Wave (pp 76-77), on the use of brodifacoum poison, an anti-coagulant used by the Department of Conservation in NZ to kill pests. It is seen under the trade names of Talon and Havoc. An animal may get a small sub-lethal dose of brodifacoum, and later more doses until a critical poison level is reached & the victim dies. A single sub lethal dose however can remain with an animal for its whole life. Brodifacoum has a half life of 157 days in the soil. Some insects can consume brodifacoum baits and have no ill effect but of course if they are part of a bird’s diet they can be catastrophic.

As DoC do not monitor insects before and after brodifacoum operations, the consequences of their activities on endangered species is unknown.

This is how it was that the Auckland Regional Council poisoned nearly 60% of the resident population of endangered North Island dotterel at Tawharanui Regional Park in 2004: through eating brodifacoum baits and poisoned sand-hoppers!

When I read of these incidents I’m always left pondering as to whether the NZ agencies that purport to be saving our native birds are actually being truthful?

Connect the dots here…
1) DoC doesn’t monitor insects before & after poisoning operations
2) Insects eat brodifacoum
3) Dotterel EAT insects
4) 60%, in this instance, of the already endangered dotteral population dies

Is this really rocket science people?

Hear the birdsong in the Ureweras, they’ve hosted rats, stoats, possums & deer for over 100 years & no 1080 drops (the GrafBoys)

Published on Oct 5, 2014

The Department of Conservation says it needs to use 1080 poison to kill rats and stop rat plagues. Rats have been present in New Zealand forests for over 700 years. This clip looks at various areas where 1080 poison has never been used, and one example of where it has. This is an observation only, but does raise some questions about areas where 1080 is used …

In 2011, DoC Killed 77% of Tagged Kea with 1080 Drop in North Okarito

From thecontrail.com
Oct 31st 2011

Historical evidence of the destruction that 1080 wreaks. Time for this poison to be shelved.

Last month (article dated 2011 note) 7 out of the nine tagged Kea monitored by radio tagging during the recent North Okarito aerial 1080 drop were found dead.

DoC assured the public that 1080 bait types had been modified so Kea would not be affected. In fact, we think all they did was to reduce the wax content of the manufactured pellets in the assumption that they would be hard enough to deter the birds from eating them.

The  iconic parrots, Kea and Kaka have very powerful beaks they use to tear apart tree limbs to access food.  GO FIGURE~!
