2020 Spring bird survey results from (1st September to 30th November) The percentage % frequency of bird observations at Folland Park, River Torrens Linear Park, Mutton Cove and Barker Inlet South Council reserves is the main measuring indicator used for this summary report. The below frequency category defines the frequency size from a given observation sample. For example, the Noisy Miners in the below chart indicates a frequency of 28%, this means that the bird fits within the large observation frequency category. Note that species frequency is calculated by how many times you observe that species in each individual survey and is an important statistic to measure species abundance in a given habitat. Below is an example of a 100m transect at Folland Park with 4x (50x50m2) quadrant titles:

4 2020 Spring Bird Survey Report

Discussion of Results It appears that large frequency of White-Plumbed and Red Wattlebirds were observed at Folland Park over the spring months. The large number of Red Wattlebirds observed maybe due to the nectar from flowering of the Red Mallee and a variety of Acacia species through this period as the weather has become a little warmer. It is disappointing to see again a large frequency of Noisy Miners at River Torrens again. This has been a common trend observed throughout 2020 along with high numbers of Rainbow Lorikeets. Hopefully as the 2018 revegetated zones establish at Pittman Park other such as New Holland Honeyeater and other small honeyeaters maybe attracted to occupy in this area. We may need to encourage the growth of native creepers such as Hardenbergia to provide hiding places for honeyeaters and increase the native grass patches to provide a seed source for small birds to feed from in the coming years. There was a medium frequency of Singing Honeyeaters observed at Mutton Cove Reserve, higher than any other time reported probably due to the various eucalyptus and acacia species flowering in the warmer months along the northern buffer of Mutton Cove Reserve. Barker Inlet Wetlands South is the first survey addition picked up in this report. Other wetland survey results will be included in the report as we gain more observations. As you can see there is high number of species diversity as you would expect from a freshwater wetland system, however the above pie graph indicates that there was generally a low number of individual bird species observed. There will be more commentary to come on local wetland birds as we gather more observations in future months. Coastal Sand dunes, Biodiversity Park, Dry Creek, Barker Inlet Wetlands and Whicker Road Wetlands observations were not extracted for this report as there was not enough individual survey observations undertaken across the spring period at these sites to discuss observations. If you want to find out more information about these sites please go to the Atlas of Living Australia “Port Adelaide Enfield Flora & Fauna Monitoring Project” Webpage. To find out more about these bird surveys and trends you can visit the CityofPAE Biodiversity webpage where you can find more detailed reports about bird research undertaken locally and across Greater Adelaide area. Stay tuned for the next project report summary from summer 2020-21.
