Are Pipits actually thriving across the Preserve? Probably Not.
There are still a big amount of Pipits across the Preserve; However, the Pipits are not thriving as before based on the following reasons.
- The number of Pipits keep growing till 2015, but had a sharp decrease from 2016.
- The gathering area of Pipits moved away from the dumping site since 2015.
We can conclude that the Pipits were not thriving since 2015. But we don't have 100% confidence that the Pipits were influenced by dumping site due to 2 reasons.
- We are not sure of the exact construction time of dumping site. 2015 was just a hypothesis we raised based on the visualization.
- The population of other bird species also decreased at the same time even if they live far away from the dumping site.
Does the set of bird calls are Pipits? No.
By combining the visualization and machine learning methods, only 1 out of 15 test birds can be confirmed as Rose-crested Blue Pipit. And 2 out of 15 are similar with the Pipits. In addition, The Pipits confirmed as Rose-crested Blue Pipit lived away from the dumping site.
