Percentage of bird surveys from each study the birds in the Great Western Woodlands. The Great data source. Western Woodlands is a 16 million hectare area incorporating much of the Goldfields, between the wheatbelt in the west and the Nullarbor in the east (see photo and map, front page). It is the largest intact Mediterranean woodland on Earth. Because of the size and remoteness of the area, little is known about the distribution and ecology of the birds, the impacts of introduced species, fire, and human disturbance, or how we should best manage the area to help conserve the birds present. As a result, BirdLife Australia will be studying the birds of the area over the next few years. BirdLife Australia will be conducting surveys throughout the Great Western Woodlands in each season to the end of 2014 and we need your help to get out there! If you’re interested in birdwatching in some spectacular parts of the state please contact the Project Coordinator, Liz Fox at liz.fox@birdlife. org.au or phone 0427 947 009. At the end of 2011 BirdLife Australia received an Environmental Community Grant from the WA Department of Environment and Conservation in order to collate existing bird data from the Great Western Woodlands, and to conduct community engagement. Below is the outcome of that grant. • DEC threatened fauna database Existing bird data • DEC fauna survey database In order to collate all previous bird records from within the • DEC waterbirds database Great Western Woodlands (GWW), a literature search was • Hooded Plover database conducted for all bird data recorded from within the GWW boundary. The search included the following: • Journal articles and reports • Environmental survey reports for mining companies, • Bird Atlas 1 (BirdLife Australia) conducted by consultants • Bird Atlas 2 (BirdLife Australia) • Unpublished data held by individuals • BirdLife WA database All data were collated into a single database. In total, the • Global Biodiversity Information Facility (online database database contains bird records from 3330 locations (Figure containing records from numerous museums and 1).

The database does not yet contain Figure 1. All bird survey locations in the Great Western the data derived for this project from the Easter Woodlands. tagalong surveys (see below). Based on the number of surveys conducted, the BirdLife Australia Bird Atlasses contributed the highest number of records (Figure 2), with almost three quarters of the data coming from this volunteer sourced database. The Bird Atlas is an invaluable source of information as the data are recorded in a standard way, all recorded in a single database, and can be used for analysis many years later to answer questions not even considered when the bird surveys were first conducted. If you have any Bird Atlas forms lurking away in a cupboard somewhere, make sure to send them in as you never know when they will form a vital part of some analysis! The total number of bird species recorded from within the GWW is 206. This includes several rare species, such as a Yellow Bittern recorded from Kalgoorlie in 1967 (the first record of the species in Western Australia), and historical records of species now extinct from the region such as the Thick-billed Grasswren. Excluding these rare records, there are approximately 180 Page 4 Western Australian Bird Notes, No. 143 September 2012 Birds in the Great Western Woodlands, ctd ‘common’ species occurring in the GWW.
