I have booked to go to Melbourne from 23 to 29 May. This is mainly to attend the RAOU (BA) AGM & Members' Day to be held on 25 May and I thought I might as well stay for the BOCA AGM on Tuesday night as well. (Members will have received notices about time & place.) I will have stocks of the following report there, for anyone interested. I also intend to have a poster display about it. It is an opportunity to obtain it without postage costs etc.

The long-awaited report: "Canberra Birds: A Report on the first 18 years of the Garden Bird Survey" is now available and already selling fast. It is pleasing to note that the response I have had from people so far about it has been impressive. It is full of good stuff that has never appeared before, at last a fitting tribute to all those who have contributed to the GBS.

This is a detailed analysis of the Garden Bird Survey (GBS) that has been run by Canberra Ornithologists Group (COG) since July 1981. The report is based on the first 18 years of continuous data, from 46273 observer weeks of data, from 1151 observer years of data, from a total of 277 sites. It for the first time, fully describes the survey's history and methods. It includes a summary of urban bird surveys throughout the world (especially Australia). It addresses how observer activity affects results and the importance of habitat at the range of sites. It demonstrates observer differences in results. It details how recording rate relates to assessed abundance of birds and how the connection alters, according to the migratory and social behaviour of birds. It makes vital comparisons between results of the GBS and the COG ACT Bird Atlas. It describes frequency distribution by year at which species were recorded and found breeding. It shows how species diversity and total abundance of bird fauna varies over the year (by month). It describes how residency of birds is assessed. There are 34 Figures (graphs) and 2 data Tables in this first section. (There is a total of 303 individual graphs in the book.) Conservation aspects are also addressed.
It has 41 pages of text (in standard sequence with one exception) on 163 species where the data are sufficient. This covers monthly patterns of abundance and/or long term trends in abundance, such as increases, decreases and stability. Also timing and duration of all stages of breeding is given (if recorded). Monthly patterns are interpreted relative to migration, changes in habitat use over the year, seasonal changes in behaviour and breeding. It includes 15 pages of clearly set out graphs of both monthly and long-term abundance, over the 18 years, for 120 species. It includes 8 Appendices of detailed statistical and other supplementary information (statistics on occurrence and breeding of all species and statistics on all sites, plus other items) and 149 references and a comprehensive index.
The report is 128 pages in length, printed in plain black and bound. It is set out very compactly (avoiding blank space). Although it is in part based on the same dataset, this report includes an extra year of data and far more detailed analysis and none of the pictures that are in the book Birds of Canberra Gardens. (But it does have three original pictures) That book, that you have probably seen, was published in 2000 by COG (and usually retails for something over $30). This report is very different in concept, coverage and design.
This price on this report is $19.00 (normally plus package and postage of $3.50) and will be available only from:
