 <b>i. Import two CSV Files (Birds)</b>
-* 2081 Training Birds (Metadata)
-* 15 Test Birds (Provided by Kasios)
-<b>ii. Fix Data Quality Issues</b>
-* Change File ID from numeric to character
-* Change coordinates to numeric
-* Change Date from Character to Date
-* Omit the two NA values for the Y coordinate.
-* Clean the Dates (All standardise to m/d/y. For missing month/year, I will replace with NA. For missing day, I will impute as 1st day of the month.)
-* Clean the Timing (Standardise all to 24 hour formatting. Use “.” instead of ":")
-* Clean the Vocalisation Type (Standardise all to lower case. For values consisting of both ‘song and call’, change to ‘call’, assumed as a sign of distress while ‘song’ is assumed as the default)
-* Clean the Quality (Recode ‘no score’ as ‘NA’)
 <b>iii. Data Manipulation</b>
-* Extract out the “Year” and “Month” from the date, as new columns
-* Create a new column for Quarter (Q1,Q2,Q3,Q4) & Season (Spring, Summer, Fall, Winter)
