Since 2005, the MFBRP has focused much of our research on the Maui Parrotbill (Pseudonestor xanthophrys). With a single population left in the wild (502 +116) and only a small captive flock, the Maui Parrotbill is at a high risk of extinction. Our research focuses on the mechanisms of Maui Parrotbill survival and productivity. To this end, we hope to isolate limiting factors for the survival of adults and young birds as well as for nest success in order to better help the Maui Parrotbill endure into the future.
Our recovery program goals are to:
- Maintain and increase current population
- Establish a second population on the leeward side of Maui
What we need to know:
- Is the population declining, increasing or stable?
- How do known threats limit population size?
To meet these goals we are currently:
- Color-banding and resighting Maui Parrotbill in Hanawi NAR at two field sites
- Locating and monitoring nests to investigate productivity
At what age do Maui Parrotbill first breed? What proportion of the population is breeding? What is their breeding lifespan? What is their recruitment rate? What is their egg fertility? Is their annual variation in productivity?
- Continuing predator control in areas with active Maui Parrotbill breeding activities
- Mapping territories, densities and distribution
- Observing foraging activities in native and non-native habitats
- Supporting the captive breeding efforts through the collection of eggs and adult birds from the wild
500 birds is barely a viable population and vulnerable to extinction from stochastic and demographic events
