Least Tern (Sternula antillarum)
Date: 5 September 2008
Location: Schell-Osage Conservation Area (Missouri, United States)
Number observed: 3
Notes:
Flying and calling. Call was not like the adult birds I'm used to hearing, so I theorized that they were immatures. The birds were quite distant, but what I could see of the plumage seemed to support this idea.
