A Quick Statistical Look

(An American White Pelican was seen by the DVOC team during the 1984 event)

As people ask about the World Series one of the most common questions is "Do you get (the name of a species)"? The answer is almost always - Yes! Frankly in order to get the totals we get we need to "get everything".

Here is a brief statistical analysis of the DVOC's 25 years of the World Series
Total species identified - 278 species
Highest single year - 231 species - 2003
Number of species identified all 25 years - 106
Number of species missed one year - 22
Number of species missed two years - 20
Number of species missed three years - 14
Number of species missed four years - 8
Number of species missed five years - 6

Number of species identified only once - 11 (American White Pelican, White-faced Ibis, Common Eider, Purple Gallinule, Ruff, Black-headed Gull, Arctic Tern, Yellow-bellied Flycatcher, Cave Swallow, Orange-crowned Warbler, Lapland Longspur)
