This is the start of a short series about boobies. I feel my reasons for liking the bird are quite obvious, despite its species' obvious racist tendencies.
Some may claim that it isn't racism, on account of their being different species, however I think think that their choosing is based on a superficial difference (i.e. their blue feet). While two animals are said to be of species if they would naturally mate to produce fertile offspring, I feel that the blue footed booby's racism is the driving factor between the differences here.
Note the display of racial acceptance inherent in the boobies' mating rituals. Sometimes the youtube video below doesn't render; if so, refresh.
You can practically hear them saying, "I have blue feet. I have blue feet. Let's make a master race through exclusive breeding."
