How it works

Starting on April 28th, follow David Steel (@SteelySeabirder) on Twitter for the World Cup of Seabirds (#SeabirdWC2020). Every day, David will post polls allowing the Twitterverse to vote on their favourite seabird!

The voting opens at the time and date (in GMT) on the roster and will be open for 24 hours! Winners will be posted on this site and on Twitter!

Maybe you like it because of it's interesting life history, or maybe their extreme attributes, or maybe you just like the way they look! May the "best" seabird win!

Species selection

Because there are around 350 species of seabirds in the world, it would be impossible to have a competition that captured every single one. To get around this, the team decided to limit the number of species to 32, which would allow for 15 rounds of voting (4 birds per round for 8 rounds, 2 birds per round for 4 quarter finals, 2 semi finals and 1 final) starting on April 28th and ending on May 5th with the winner being announced on the last day of the World Seabird Twitter Conference (May 6th; #WSTC6).

The team weighted the selections by the 5 major ocean basins to take into account the fact that some oceans have fewer species than others. This led to a selection of 2, 5, 4, 16, and 5 species for the Arctic, Atlantic, Indian, Pacific and Southern Oceans respectively.

The team each selected the assigned number of species from each ocean basin. The selections were compared and species with the highest number of votes were added to the tournament roster. However, in some cases, the full roster was unable to be filled due to multi-way ties in the number of votes. To overcome this, the team had a second round of voting to select the final roster.

Competition rounds were randomised.
