Our overarching goal is "Improving the world for birds, one predator at a time."

Background information

The Huia trapping group was established in 2018 by Sam McClatchie, Brendan Boughen, and Dave Minty, who are the administrators of the group. Our goal was to bring together neighbours who were already involved in predator control, and those who would like to be involved, in a mutually supportive group. More experienced trappers provide advice and help to solve problems. We have sourced traps that have been loaned to new trappers, and used to increase our spatial footprint. We continue to obtain small grants to fund new initiatives, like monitoring bird song, or expanding the number and variety of traps that we can deploy. We are particularly interested in assessment of new trapping and monitoring technology. We use the scientific expertise in the group to analyse trapping data and conduct applied research. We have surveyed trapping activity in the Huia community using online polling, and in the future we plan to participate in community outreach by attending the Karamatura Farm Day.

We gratefully acknowledge financial support by Ecomatters, Waitakere Ranges Local Board and kind support of Andrew Stein of the Auckland City Council.

This article in the Medium magazine "Towards Data Science" describes some of our trapping efforts, incorporating videos to illustrate animal behaviour around traps.

Improving the world for birds, one predator at a time.

This article in the same magazine describes a trial use of the Cacophony bird monitor as a tool to monitor trapping success at Huia.

Here's how we add value to the citizen science data we are generating.

Huia trapping group effort over time
Trapping effort in Huia has increased over the past 4 years. The plot shows traps that have captured at least one predator. © S. McClatchie
Finding a way to monitor the success of our trapping in improving the world for birds:
Testing the Cacophony bird monitor to detect effectiveness of our trapping
We are using the Cacophony bird monitor to test whether it is a useful tool for monitoring the success of neighbourhood trapping. These are some of the data that we have collected so far at Huia. This monitoring is continuing, and will expand as we acquire more bird monitors. © S. McClatchie
Comparing the catch efficiencies of our different trap types:
Using our trapping data to compare trap efficiencies
We are interested in the relative catch efficiencies of different traps, and are using our data to compare DOC200 and Goodnature A24 catches of rats and mice. © S. McClatchie
