We hypothesize that the Rose-crested Blue Pipits may have been affected by certain activities at their old hangout location at the alleged dumping site. From Task 1 we see they had been found there in large concentrations pre-2014, had stopped singing in 2014 which shows they may have been under distress, and had moved away from there since 2015. These observations point to the high possibility that something bad had happened at that location in year 2014 which caused them to move away.
On top of these observations centered around the Pipit, it was also found that another 7 species of the 19 species had obvious changes in their numbers and/or their spatial distribution in years 2014 and 2015, and these 7 species do not live near the dumping site. It seems the problem is more than just the alleged dumping site and the Rose-crested Blue Pipits, as nearly half of the species had shown signs of moving away or reductions in numbers and spatially these effects are observed throughout the Preserve, not just at the alleged dumping site.
From Task 2 we found that only two out of fifteen test files were recordings of the Rose-crested Blue Pipit, and both these files were recorded at locations far away from the usual hangout locations of the species. In addition, some of the fifteen test files do not appear to be recorded in the Preserve, as their spectrograms did not match any of the 19 species identified and provided by Mistford College. Overall, the set provided by Kasios did not support their claim that the Pipits are being found across the Preserve.
As many species started showing signs of change in 2014, we should investigate the movement of vehicles and visitors in the Preserve in the year 2014, considering the fact that in mini-challenge 1 2017 the dataset was only from May 1 2015 to May 1 2016. As the effects from negative externalities are not only constrained to around the dumping site but also observed throughout the Preserve, this may be related to the finding in mini-challenge 2 from 2017 that Methylosmolene was detected in their smokestack emissions, and if that was true, that could be causing the air in the Preserve to be undesirable for the birds to live in. Therefore investigations should also be carried out about the smokestack emissions and general air quality in the Preserve.
The current collection strategy does not ensure an equal number of recordings being collected each period, which makes it difficult to support or refute the claim that the Pipits or any species are still living happily in the Preserve because it is compounded by the fact that some years have more recordings than other years overall. What seems like a reduction in species numbers during spatial analysis could actually be due to the reduction in recordings for those years. Moving forward, a consistent methodology for bird recording collection should be adopted. Explore the possibility of replacing the human collectors with sensors, so that the sensors can be configured to collect recordings at equal time intervals of the day, month and year.
