Sterna

Sterna is a genus of terns in the bird family Laridae. Sterna is derived from Old English "stearn" which appears in the poem The Seafarer; a similar word was used to refer to terns by the Frisians.[1] It used to encompass most "white" terns indiscriminately, but mtDNA sequence comparisons have recently determined that this arrangement is paraphyletic. It is now restricted to the typical medium-sized white terns occurring near-globally in coastal regions.[2]

Genus Sterna - typical white terns

For the "brown-backed terns" see genus Onychoprion.

gollark: But it isn't the average, and is... maybe the sum, I can "check".
gollark: No idea, I don't actually know how it works beyond something something time domain frequency domain.
gollark: I found a video™ which explains that the peak at zero occurs because the numbers are not centered on zero.
gollark: This would be easier if I actually knew anything about which frequencies each index corresponds to, hmm.
gollark: Maybe I should take the logarithm of it instead.
