AVA’s Relative Abundance Survey for Urban Birds 2015

The AVA carried out the second RASUB over two Saturdays in April this year with the help of the public. The species counted were the Javan Myna, Common Myna, Rock Pigeon, Asian Glossy Starling, Asian Koel, House Crow and Black-naped Oriole. The Black-naped Oriole was included as it is known to foster the Asian Koel.

A total of 1,606 birds were counted in 50 locations compared to 784 over 23 sites in 2014. The Javan Mynas topped the list just like in 2014.

Results: Javan Mynas 832, Rock Pigeons 531, Asian Glossy Starlings 96, Black-naped Orioles 52, House Crows 48, Common Myna 39 and Asian Koel 11.

The results of this year’s survey is similar to the survey carried out in 2014, where Javan Mynas were the most commonly seen species and achieved the highest count among the target species. House crows and Asian Koels showed similar distributions in locality, confirming that Asian Koels are brood parasites of House crows in Singapore.

The AVA intends to continue with this census every year in order to monitor the trend of these urban species and supplement its own surveys and studies.
