New-Zealand's bird of the year
Every year New Zealanders vote en masse to decide which species gets the bird of the year trophy. The contest is organized by the Forest & Bird agency which allows each person to give points to up to five birds (first pick gets 5 points, second 4, …). Your job is to decide this year's winner from the messy dataset that's been pre-loaded for you as bird_df.
The dplyr package has been pre-loaded for you.
