In late February our colleagues at Wild at Heart Legal Defense Association sent two delegates to the Annual Jeju Wildlife Research Center Workshop on Jeju Island, South Korea. Jeju Island, along with Taiwan, Southern Japan, and Southern China are the breeding areas for the IUCN Red Listed Fairy Pitta Pitta nympha. Dr Lin Reuy-shing of the Taiwan Endemic Species Research Institute and Mark Wilkie of Wild at Heart Legal Defense Association delivered presentations on the Fairy Pitta in Taiwan.

Dr. [Scott] Lin Reuy-shing, Assistant Senior Researcher at the Taiwan Endemic Species Research Institute has studied the Fairy Pitta for the last decade and is considered an international expert on the species. Dr. Lin delivered a presentation titled (abstract below), "A review and perspective of Fairy Pitta research in Taiwan."

Mark B. Wilkie, a South African expat, works as a naturalist for Wild at Heart Legal Defense Association, Taiwan. He has been involved with Fairy Pitta conservation in Taiwan for the past five years. He also serves as a super moderator on Birdforum the net's largest birding community dedicated to wild birds. Mark Wilkie delivered a presentation titled (abstract below), "Conservation and threats to the Fairy Pitta: The Huben IBA, Taiwan." The presentation included the likely negative impact that the Hushan Dam Project will have on the Fairy Pitta and other threatened species such as the Swinhoe's Pheasant Lophura swinhoii and the unique Taiwan population of humpback dolphins Sousa chinensis.

Introduction

Contact with Jeju Wildlife Research Center (JWRC) was first established in January 2007 before the 2007 Jeju Wildlife Research Center Workshop. We were not able to attend this workshop but interest in the work of JWRC developed. Contact was maintained through e-mails with Yong-chang Jang, JWRC External Cooperation Director. Yong-chang Jang also had contact with Wilkie through Birdforum.

In August 2007 Eun-Mi Kim, JWRC President, attended the 2007 International Symposium for the Fairy Pitta held in Dounan, Taiwan. She delivered a presentation titled, "The distribution and habitat of the Fairy Pitta on Jeju Island, South Korea." At the symposium Kim met both Lin and Wilkie. The idea of future cooperation was discussed at the symposium and Lin and Wilkie were invited to the 2008 Annual Jeju Wildlife Research Center Workshop. JWRC kindly offered to host Lin and Wilkie for the period of the workshop and Wild at Heart Legal Defense Association (Wild) agreed to fund the airfare and additional costs.


Goals

The goals of the trip were:
- To establish cooperation on Fairy Pitta research between Korean and Taiwan researchers.
- To propose the use of standardised research methods for better comparison of regional data at an international level.
- To give Korean researchers a better understanding of Fairy Pitta research that had been undertaken in Taiwan and to share ideas on future Fairy Pitta research and conservation.
-To create awareness of the threats to the Fairy Pitta in Taiwan and the conservation shortfall.
- To gain a general overview of the nature of Fairy Pitta habitat and nesting sites on Jeju and threats facing the species.


The Trip

Friday, February 22, 2008


                             Folklore & Natural History Museum of Jeju.

We arrived at Jeju International Airport just before 14:00 and were met by Eun-Mi Kim, JWRC President, and her husband, Chang-Wan Kang, a well known Korean wildlife photographer. From the airport we went to the Folklore & Natural History Museum of Jeju where we met the museum's Wan-Byung Kim. Mr Kim introduced us to the natural history of Jeju Island and also allowed us to examine two Fairy Pitta specimens in the museum's possession.

From the museum we proceeded to the National Ecology Experience Exhibition Hall at the Halla Arboretum where we were to meet up with other delegates. The hall was also the venue for the workshop. There was about an hour before the other delegates from Seoul arrived so we were able to spend a little time going around the arboretum and doing a little birding.

About an hour later we met up with local JWRC members and delegates from the Korean mainland. We viewed a photographic exhibition of Jeju birds and other wildlife that had been put up for the workshop and were also able to go around the National Ecology Experience Exhibition Hall.

Sunday, February 24, 2008


                                        Hallasan National Park.

This day was spent in the field. The group started the day going around the Halla Arboretum. From the Halla Arboretum the group split and embarked for Southern Jeju. The second group, led by Mr. Nam-Joon Ji, traveled south via Hallasan National Park. Mount Halla (1950m) is South Korea's highest mountain. Hallasan National Park is a UNESCO World Natural Heritage Site. Jeju's unique lava tubes are a not to be missed sight on Jeju. From Daepo-dong on Jeju's southern coast the group followed the coastline eastwards through wetlands and coastal areas all the way back to Jeju City in the north.

Monday, February 25, 2008

Monday was devoted to Fairy Pitta research. Eun-Mi Kim, Chang-Wan Kang, Ruey-Shing Lin, and Mark Wilkie spent the day visiting and viewing Fairy Pitta habitat and known previous nesting sites. Fairy Pitta arrives in Jeju in mid to late May. This is about a month later than those arriving in Taiwan.

Tuesday, February 26, 2008

We planned to visit two nesting sites on Tuesday morning before our flight back to Taiwan. Because of weather conditions we were only able to visit one site. Snow prevented us from getting to the second site.


Conclusion

The Workshop was a great success. For us, it helped in establishing future cooperation for Fairy Pitta research and conservation and gave us all a better understanding of where research is at in South Korea and Taiwan. It also gave us a greater understanding of threats to the species within its international range. It allowed us to share ideas. Eun-Mi Kim will be coming to Taiwan in late April for about a week. She will deliver a presentation to the Taiwan Endemic Species Research Institute and also spend time in the field in the Huben-Hushan area with Dr. Lin and his team.

ABSTRACT

Tropical and subtropical Asia is currently confronting particularly severe forest conversion pressure. The vulnerable Fairy Pitta (Pitta nympha) is an understudied passerine which breeds in the low-elevation forests of eastern Asia and probably winters on Borneo. Because of severe habitat loss, suitable habitat within its breeding and wintering ranges as well as on its migration routes might not be sufficient to maintain its population. Additionally, there are few published intensive studies on migrating pitta species. Thus, there is an urgent need to establish knowledge of all aspects of their ecology and biology and then to propose suitable management measures to conserve this threatened species. In this speech, I will first illustrate what we have done between 2001 and 2007 in Taiwan, and then make a brief introduction to some of our ongoing research projects. Finally, I will outline a conservation plan for the Fairy Pitta over the next decade based on our current knowledge.

Historically, Fairy Pitta was believed to be a rare summer breeder in Taiwan. After a preliminary survey in Huben Village, Linnei Township, Yunlin Couty in west-central Taiwan in 2000, we found it probably was not as rare as previously thought and we thereafter initiated long term studies. At first, we tested the effectiveness of using playback of recorded calls to census the presence and abundance of Fairy Pitta in early summer of 2001. Since the detectivity of Fairy Pitta was significantly increased when playback was used, we then started using playback to survey the distribution of Fairy Pitta and to monitor the population status on different spatial scales, i.e., Huben Village, Linnei Township and Douliou City, and finally the whole of Taiwan. Additionally, the data was used to model the potential spatial distribution in areas we did not visit.

The diet of nestling Fairy Pitta was also studied by videotaping from 2000 to 2002. Results indicated that Earthworms were the most important food item for all broods and occurred in more than 73% of the adult’s feeding visits. Also, adults usually brought 1-3 items at each feeding visit to nestlings, and the prey sizes were usually 2-10 cm in length. The total number of food provisionings to provide food for nestlings was estimated to be around 900-1000 based on a brood observed for the entire nestling period.

In order to propose feasible habitat management strategies for land managers, we studied nest site selection and the possible effects of habitat conversions, i.e., bamboo plantation, over three breeding seasons from 2004 to 2006 on Fairy Pitta in Huben Village where the area is predominantly planted with bamboo (Dentrocalamus latiflorus). In general, Fairy Pitta chose to nest in areas with increased canopy cover and a diversity of trees coupled with decreased shrub density immediately around the nest and moderate small shrub density near the nest and situated at a moderate distance from the nearest tree. Also, nests built in places with higher overhead cover, with a steeper downward slope and with greater difficulty to access were more successful. Although bamboo density was not included in the best nest site selection models, it did significantly negatively correlate with the diversity of trees. Therefore, we recommend that managers protect remaining broadleaf forests and restore similar habitat in areas of rough terrain, usually found along valleys, to enlarge areas of suitable habitat.

Since nest predation is the most important factor causing nest failure for Fairy Pitta, we monitored their breeding success in Huben Village from 2003 to 2007 and identified their nest predators by continuously digital video-taping during the 2006 and 2007 breeding seasons. Snakes were the most important predators, followed by large mammals, such as macaque, mongoose and civet. A Crested Serpent Eagle was observed once attacking nestlings.

Finally, we report on some resighting records from 152 color-banded Fairy Pittas that were captured in 2001, 2004 and 2005 to index their breeding site fidelity and to compare the differences in return ratios between adults and fledglings, and also between males and females within the Huben Village study area. Between 2004 and 2007, we resighted Fairy Pitta with bands 19 times, and of those, ten individuals were identified from fifteen resightings. The return ratio of fledglings (1/99) was significantly lower than it was in the adults (9/53). Among nine adults, only two were female. However, the difference between the two genders was not significant. The mean distance between banded and resighted positions was around 130m, ranging from 19-300m. Since the diameters of the various Fairy Pittas’ territories also ranged from 100-300m, it indicated that adults often returned to sites close to or in their original territories. The return rate of adults in Huben Village was around 16-26%. However, this value has probably been underestimated because of their secretive habits.

Currently, we are using the telemetry technique to study the fluctuations of home range and activity pattern within the breeding cycle and the movement and survival rates of young and adults during the period that Fairy Pitta stay in Taiwan. In addition, we are refining the spatial prediction models of Fairy Pitta in Taiwan and trying to estimate their population size. Probably, we will also model their spatial distribution within their breeding and wintering range. Since the connections between breeding and wintering populations are important for the conservation of Fairy Pitta, we plan to use molecular approach and isotopes to construct the spatial population structure among South Korea, Japan, China and Taiwan. If the population structure is significant, we then can use these tools to link the breeding and wintering populations in the future.

Conservation research of the migratory Fairy Pitta is generally more complicated than the other non-migratory pitta species. Based on the status quo and analyses of priorities, we outline current issues, set conservation goals and propose actions to accelerate the conservation of the Fairy Pitta over the next decade.

Conservation Issues

Inadequate understanding of population size and distribution, especially in south-east China and in its wintering range: Sighting records and surveys in small areas has been compiled. However, no extensive surveys across its distribution range have been made. Additionally, the actual wintering grounds for the species, has until now, remained somewhat of a myth.
Habitat loss, degradation, and fragmentation: Breeding habitats in south-east China and wintering habitats probably have been destroyed at a rapid rate. In other breeding areas, afforestation and modification in broadleaf forests have continuously degraded the remaining habitat.
More research work: Research is urgently needed on the ecology of habitat requirements, especially on specific structural features, landscape configurations, and amounts of habitat that are required to maintain a source sub-population in developing scientifically based management measures, such as designs of land-use projects, protected areas and habitat restoration.
Impact of climate change: Although the impact is not clear, it has the potential to affect the Fairy Pitta population through increasing temperature and uncertainties in rainfall that will certainly affect its distribution, food resources, and habitat requirements, and also through the changes in weather patterns on migration routes.

Conservation goals

Improve our understanding of the distribution of Fairy Pitta and its habitat requirements.
Initiate an international conservation action plan to reflect current knowledge.
Promote a coordinated international network of conservation partners to implement the action conservation plan.

Recommended actions

Conduct surveys throughout their distribution range to assess their population, distribution and conservation status.
Implement a standardized monitoring program within the breeding range. This is critical for all stages of conservation planning and important for monitoring their population trend, especially before the identification of wintering grounds.
Identify critical wintering habitat and study the linkage between breeding and wintering populations. These are necessary for protection and restoration because areas of their wintering habitat might be severely degraded in the near future. Methods for identifying the wintering grounds should be developed.
Monitor and track the amount, condition and configuration of the important habitat used in all phases of the Fairy Pitta annual cycle by GIS and remote sensing techniques.
Conduct research to identify areas of high-quality habitat and landscapes in terms of fecundity and survival across their annual cycle, and frequency and scale of dispersal among populations across their range. This information is valuable for their conservation.
Create well-coordinated partnerships to accelerate the implementation of conservation actions in nations where the Fairy Pitta stays or passes through.
Protect known important hotspots and retain remaining high-quality habitat. Restore similar habitat to defragmented and enlarged forest tracts that are large enough to support several source populations and other priority species. Also, examine the birds’ responses to management measures.
Develop community-involvement and scientifically sound forest management measures in areas of important breeding habitat.

The challenges of Fairy Pitta conservation reflect the status quo of many threatened forest birds in this region. To effectively conserve migratory landbirds, it is necessary to raise more conservation awareness and place more effort on carrying out well-coordinated monitoring studies beyond political borders.


Conservation and threats to the Fairy Pitta Pitta nympha:
The Huben IBA, Taiwan.

Abstract

Taiwan falls within in the breeding range of the Fairy Pitta (Pitta nympha). In mid to late April this dazzling insectivorous terrestrial suboscine passerine arrives in Taiwan to breed. The Fairy Pitta has been listed as vulnerable (BirdLife International 2001) due to a sharp decline in numbers. The Huben Important Bird Area (IBA) in Yunlin County, west-central Taiwan is an important breeding area for the species. Taiwan has a total of 53 internationally identified IBAs. For its size, Taiwan has a very high number of IBAs. Only 11 or 21% fall within totally protected areas. 17 IBAs or 32% fall within partially protected areas. That leaves 25 or 47% of Taiwan’s IBAs without any protection. Huben falls amongst those IBAs without any protection (BirdLife International 2004).

The Huben-Hushan area has been listed as one of Asia’s key sites for conservation (Birdlife, 2004). The details of the Huben IBA are as follows:-

Name: Huben IBA.
Number: TW017.
Category: A1.
Admin Region: Yunlin County.
Coordinates: 23° 43’N 120° 36’E.
Altitude (highest point): 519m.
Area: 2,200 ha.
Habitats: Artificial landscapes (terrestrial); Forest.
Threatened Species: Fairy Pitta Pitta nympha.
Protected Area Status of the IBA: Unprotected.

In this presentation delegates will be introduced to the Huben IBA and the threats facing it, most notably, loss of habitat through construction-related so-called development projects such as the Hushan Dam Project and the concreting and barricading of streams to allegedly reduce erosion. In many ways the Huben IBA can be seen as a microcosm of what is happening to the Fairy Pitta throughout its range. Briefly, some of the conservation measures and efforts that have been taken to address the plight of this species will be looked at. Finally, the point that meaningful Fairy Pitta conservation can’t take place without international cooperation is made in the hopes that a multinational effort to address the plight of this delightful forest passerine can be brought about.
