This citizen science endeavour enabled everyone from school children, senior citizens, families and community groups to participate in capturing a snapshot of Australia’s birds. In doing so, these citizen scientists played a vital role in providing important information to Birdlife Australia to help increase our understanding of the bird species that utilise backyards and gardens. The Backyard Bird Count also raises the profile of bird species throughout Australia highlighting the importance of these species and promoting a national passion for Australian birds. Birds in Backyards (BIBY) In 2000, 20 per cent of Australia’s bird species were assessed as being either Threatened or Near Threatened in The Action Plan for Australian Birds. The 2006 World Wildlife Fund’s report to the Nairobi conference on climate change predicted that 72 per cent of rainforest bird species in north-east Australia could become extinct if global warming continues unchecked. These are just two science-based messages that many of Australia’s bird species are in danger. For those of us who love and value birds, these figures are appalling. However, for many in the general community they have little meaning. The Birds in Backyards (BIBY) program is a research, education and conservation initiative which was conceived and designed primarily in an effort to make these potential bird losses meaningful to the 85 per cent of Australians living in urban and regional areas, as well as gathering data to help clarify the issues. By involving local communities and citizen scientists, the general public are helping to undertake scientific research to determine trends in bird diversity and distribution in backyards, gardens, parks and other public urban areas where the research outputs will help contribute to developing and implementing conservation strategies. 2014 Aussie Backyard Bird Count Statistics The following statistics relate to the Macedon Ranges Shire Council region during the Aussie Backyard Bird Count that ran from the 20th to 26th October 2014: 120 observers registered and submitted 187 checklists ranging between 1 and 10 checklists submitted per observer (average of 1.5 per observer) The combined duration that observers surveyed over was 56 hours and 50 minutes Bird recordings ranged from 1 to 184 per observer, with an average of 45 birds recorded per observer A total of 5,405 individual birds were observed and recorded during the week 136 bird species were recorded (Table 1, Figure 1) Policy Number: Aussie Backyard Bird Count 2014 Date: March 2015 1 Table 1: The complete species list, number of individuals observed and reporting rate within the Macedon Ranges Shire Council boundary during the 2014 Aussie Backyard Bird Count.

Please note that bird observations that were recorded in a single survey overlap due to having the same GPS co-ordinates. Policy Number: Aussie Backyard Bird Count 2014 Date: March 2015 5 Species List: Least Common The 20 least commonly observed bird species recorded within the Macedon Ranges Shire Council boundary all corresponded to one single observation and included: Australian Darter Hooded Robin (NT) Azure Kingfisher (NT) Little Grassbird Black Swan Red-capped Robin Brown Falcon Red-rumped Parrot Cattle Egret Rock Dove* Eastern Barn Owl Satin Flycatcher Eastern Koel Song Thrush* Eurasian Skylark* Swamp Harrier Fairy Martin Tawny Frogmouth Grey Butcherbird Tree Martin Three species are introduced species (denoted by *), while two species, the Azure Kingfisher and Hooded Robin, are listed as Near Threatened (NT) in Victoria (Department of Sustainability and Environment, 2013). Two of the least commonly detected species are nocturnal (the Eastern Barn Owl and the Tawny Frogmouth), while only one is a water bird (Black Swan). Species List: Most Common The 20 most commonly observed bird species recorded within the Macedon Ranges Shire Council boundary ranged from 68 to 595 observations and included both native and introduced species (Figure 2). All 20 species are considered to have secure populations within Victoria. Introduced Species The four most commonly observed introduced species within the Macedon Ranges Shire Council boundaries during the 2014 Aussie Backyard Bird Count were the Common Blackbird, the Common (Indian) Myna, the Common Starling and the House Sparrow (Table 2). All four species overlap in their distribution and were observed all throughout the region, with the southernmost area having the highest number of observations (Figure 3). The high bird count relative to surveys conducted indicates that observers encounter multiple individuals either throughout the duration of the survey period or all together (e.g. in a flock; Table 2).

A total of seven individuals were detected in these three surveys (Table 1). Two of the three surveys which detected Powerful Owls were situated near the North eastern Council border. Seven species with a listing of Near Threatened in Victoria were also recorded within the Macedon Ranges Shire region during the 2014 Aussie Backyard Bird Count (Figure 4; Department of Sustainability and Environment, 2013). Number of individuals sighted for these species Distribution ranged from 11 four to one 1).

Policy Number: Aussie Backyard Bird Count 2014 Date: March 2015 9 Data Limitations An annual backyard bird survey occurring in gardens across Australia has the potential to be an extremely valuable monitoring tool for Australian bird species and communities. Over years, data collected from regions can be used to detect population trends for target species (both native and introduced), for different species guilds and for bird communities within specific areas. For example, detection of regional and/or national changes in the abundance and distribution of species especially those of management concern, such as downward trends of native species, or upward trends of pest species. Subsequent management actions can therefore be implemented in response to the survey results. However, some caution must be taken when interpreting the results from such a survey. The backyards that are surveyed will not constitute a random selection of backyards across Australia. Previous analyses of surveys of a similar nature have suggested that participants are more likely to be interested in birds and have more ‘bird-friendly’ gardens than the country as a whole (Dunn et al., 2005; Spurr, 2012). If this is correct, the number of birds reported from surveyed backyards could be higher than the average number present within a typical Australian backyard. Furthermore, some regions may have small sample sizes, with some areas being under-represented (or not represented at all) which will influence data interpretation and population trends within an area and across the country. Additionally, bird species that are more likely to utilise habitat associated with backyard gardens are more likely to be recorded, thus represented, in the dataset than species that are specialised to other habitat types such as forests or water bodies. The lack of presence of these species within the dataset does not imply low abundance or scarce distribution but rather their specific habitat was not represented in the survey. Survey results are also subject to temporal biases as only provide information of bird communities within a one-week period during Spring. Hence, the Aussie Backyard Bird Count survey can be said to monitor population and distribution trends within the backyards of participants during the particular time period but results may not necessarily be applicable to Australia as a whole, or the entire region specifically being analysed. The skill and experience of observers conducting backyard surveys in correctly identifying birds will vary and also influence the validity of the survey results. There were some obvious incorrect species identifications and while all efforts were undertaken to vet the data of incorrect bird sightings in regions where species are unlikely to occur, it is still probable that some mis-identifications of birds will be included in the dataset and caution is needed when analysing the results. However, a previous study has implied that identification of species occurring in participants backyards are more likely to be correct as these species are familiar to the observer and are likely to be relatively common species (Cannon, 1999). What Birds in Backyards (BIBY) Can Offer We are fortunate in Australia to have such a diverse and colourful range of native birds that live amongst us in the urban landscape. These birds provide an opportunity for people to appreciate and connect with wildlife on a daily basis and increasingly, research is linking biodiversity with a person’s quality of life. In Britain, bird life is so valued that the UK government uses information about their wild bird as a measure of the health of the environment as a whole. This environmental indicator is published alongside more familiar economic and social indicators and reinforces the point that the maintenance of biodiversity is a key part of sustainability. Policy Number: Aussie Backyard Bird Count 2014 Date: March 2015 10 But our urban bird communities in Australia are changing. Small birds, like Eastern Spinebills and Superb Fairy-wrens, were once more common in parks or gardens are now disappearing and being replaced by large and aggressive species like the Noisy Miner and Pied Currawong. Changes in our gardening practices and increasing urbanisation seem to be largely responsible for this – the simplification of our gardens and the loss of shrubs has removed important food, shelter and nesting locations. If vegetation in gardens could be managed to promote a diversity of native bird species, it will provide a valuable secondary habitat for conserving native bird populations, particularly as natural habitat continues to be destroyed. In the urban landscape, engaging with the wider community is necessary in order to turn around this habitat loss and provides a unique opportunity to engage large numbers of the general community actively in the conservation of biodiversity. Birds in Backyards encourages people to learn in their own space in order to establish an initial connection with the natural world in a somewhat unnatural setting. It is not simply about providing people with information about birds in their local area but it is about building on that initial interest and encouraging people to learn more and then take action for birds. The Birds in Backyards Program can work with your council to provide resources or collaborate on projects.
