There
are four types of "probability" plots. The first type is not probability at all but rather shows the number of times
a particular species was observed by week number from 1986 through 2009. There are 5 such plots
covering all 135 species seen to date. Note that some of these are not really identified birds but are
identifed types of birds. At the top of each of these 5 plots I list the birds that are plotted.
That will to help you find a particular bird (using Find in Page) as the order of birds plotted is somewhat random. The remaining
3 types of plots are similarly presented. They are probability of observing a species of bird by week
number from 1986 through 2009, probability of observing a species by year, and an estimated probability
of observing a species by week number for 2009.
