Here is the code that I used for this assignment
1. In which year did I observe the most individual birds? How many?
In 2014, you observed 211,249 birds.
2. In that year how many different species of birds did I observe?
210 different species
3. In which state did I most frequently observe Red-winged Blackbirds?
Missouri (MO)
4. Filter observations for a duration between 5 and 200 minutes. Calculate the mean rate per checklist that I encounter species each year. Specifically, calculate the number of species in each checklist divided by duration and then take the mean for the year.

11 2020 0.503
12 2021 0.267
13 2022 0.442
5. Create a tibble that includes the complete observations for the top 10 most frequently observed species. First generate a top 10 list and then use this list to filter all observations. Export this tibble as a .csv file saved to a folder called “Results” folder within your R project and add link to the markdown document.
