Hi all,

Please read the details of this research project, we need your support,
all sightings and photos are welcome.
And feel free to pm/email for any query. Thkq!

Asian Raptor Research & Conservation Network (ARRCN)
Spizaetus (Hawk-Eagle) Distribution & Habitat Mapping Project (SDHM project)

The Bird Ecology Study Group (BESGroup) will be acting as a local coordinator for Asian Raptor Research & Conservation Network (ARRCN)’s Spizaetus Distribution & Habitat Mapping Project (SDHM project) in Singapore. This project started in 2005, following a meeting during the 4th Symposium on Asian Raptors in Dec 2005 held in Taiping, Malaysia.

The main aim of this project is to compile data on the Hawk-Eagle genus (Spizaetus) - population, distribution and habitats and to advocate for their conservation in Singapore. Secondly, this project aimed to encourage and promote the study and research of bird ecology with the assistance of fellow birdwatchers, photographers and nature-lovers in Singapore.

Singapore has only one species of resident hawk-eagle, Changeable Hawk-Eagle (Spizaetus cirrhatus). Although this raptor may be found over many parts of the main island and some larger offshore islands, it is still uncommon. The Blyth’s Hawk-Eagle (Spizaetus alboniger) is the other species seen, but it is a rare visitor to Singapore.

Help from Birdwatchers Needed
Birdwatchers and nature-lovers can play an important role in this bird study and research project by sharing and contributing their sightings and records of this bird (current as well as past). Please send all all information on sightings, nests, nesting behaviour, breeding data to email address:

BESGroup as Coordinator
As coordinator, BESGroup will collect, check, verify and collate data from all keen to take part in the project. The data will then be sent to the Main Project Coordinator in Japan after which it will be posted on the ARRCN website:

Data Collection and Data Form formats
All sightings and records are to be entered into a Data Form, which is available from the ARRCN website above or from us.

In addition to the Data Form, any record (current as well as past), e.g., digital photos of the bird, habitat, nest & other behaviours will help us better understanding their behaviour and their habitat.

Sensitive Data
Sensitive data, such as photography or exact GPS coordinates of the bird’s nests/nesting locations, and nest sites are not to be included in the main Data Form. However, they may be included in a separate SDHM Data Form marked as “Nesting Location / Site and Nest/Nesting Spizaetus photos Data Form”. Exact GPS coordinations of the birds will not be uploaded to the SDHM project section on the ARRCN website in order to protect the birds from possible poaching and other indiscriminate human activity.

For an easy reference, participants may submit data using maps / locations from the Singapore Street Directory, Google Earth or any GPS system available. All submission must reach us by the End of September 2006.

Calling for Volunteers!
If you are interested in participating, please contact us at our email address: or log on to Bird Ecology Study Group website at for information updates.

We needed Volunteers to look out for these magnificent birds and report their sightings to us. If you and your friends would like training on how to spot these birds, etc, we will be more than delighted to conduct workshops aimed at getting volunteers familiar with these birds and to promote bird study among more birdwatchers.

For queries and to get a copy of the Data Form, you can contact me at: . Thank you.

All sensitive Data shall be kept confidential for the sole puropse of research and study of this bird and analaysis of their habitat, populations and distribution and not revealed to other source.
