Task 1 Insights

Using the bird call collection and the included map of the Wildlife Preserve, characterize the patterns of all of the bird species in the Preserve over the time of the collection. Please assume we have a reasonable distribution of sensors and human collectors providing the recordings, so that the patterns are reasonably representative of the bird locations across the area. Do you detect any trends or anomalies in the patterns? Please limit your answer to 10 images and 1000 words.

Note: Since we only have sufficient data points for most of the species from Year 2010 onwards, we will exclude any bird recordings before Year 2010. Also, as we have recordings only for Q1 in 2018, Year 2018 is also excluded from our analysis.

• Bent-beak Riffraff: They are predominantly found in the western region of the Preserve, but their hangout spots are not consistent through the years.
• Blue-collared Zipper: In Year 2014, they were only making calls and not songs. In Year 2015, they were not spotted in the Preserve at all. In Year 2016, they returned to the Preserve and went back to their favorite spot pre-2015.
• Bombadil: They have stayed in the same location in the northeastern part of the Preserve between 2010 and 2017, and no major changes in their spatial distribution were observed.
• Broad-winged Jojo: They have a favorite spot at the southwestern part of the Preserve. There was an anomaly in year 2015, as high concentrations of them were found away from their favorite spot. They were only making calls and not songs. They returned to their favorite spot in Years 2016 and 2017, but overall their concentrations have dropped. This suggests that something may have happened in Year 2015 which caused them to stop singing, and subsequently experience a drop in their numbers overall.
• Canadian Cootamum: They have a favorite spot in the northwestern part of the Preserve. No major changes in their spatial distribution were observed.
• Carries Champagne Pipit: They have a favorite spot at the southeastern part of the Preserve and had not moved away from it throughout the years. While they consistently make calls in that location each year, their songs are rare in general and they are found singing in different parts of the Preserve in different years.
