From the first week in May 1987 until the end of 2018, when they were on their property "Koobabbie" in the Northern Wheatbelt of WA, Alison and John Doley collected data on every species of bird they saw each week. Data were recorded on a booklet prepared by CSIRO Division of Wildlife and Rangelands Research for its 1987-1990 bird atlas (Saunders and Ingram 1995). This booklet provided a list of all species known to have occurred in the central wheatbelt and divided the year into 12 months and each month into four weeks; that is, each year had 48 weeks of potential observations. Any species seen on "Koobabbie" that was not listed on the booklet was added to the list. The Doleys also made extensive notes about their observations at the back of each year’s booklet. These notes, together with the raw presence data, comprise this data set. The data recorded each week consisted of a tick for every species seen that week. For example, one Red-capped Robin seen once during a week was recorded as a tick, as were 100 Galahs seen every day of that week.

During 1970, Carnaby's Black Cockatoos, C. latirostris were shot in Western Australian pine plantations at Gnangara and Somerville (now the Perth suburbs of Murdoch, Winthrop and Booragoon) and in pine plantations and native forest to the east of Mundaring and Sawyers Valley. These photographs are of Carnaby's Black Cockatoo tails and have an accompanying excel file with recorded specimen data, derived from original specimen sheets.
