A migrating muster of storks

Yesterday I spotted a muster of storks (sometimes, at least according to Wikipedia, called a phalanx of storks) overflying the Zurich airport in Switzerland, at an altitude that made them nearly impossible to see:

In fact, I could not see whether they were in fact storks. Fortunately, I had my camera with me, and it has a terrific photographic lens:


I mentioned in an earlier blog that when storks are juveniles in Europe they are taught flying skills by their immediate peers, and there are in fact two groups of storks: those with lessor flying skills that overwinter in Spain, and those with better flying skills that overwinter in Africa.  Interestingly, scientists have attached accelerometers to storks, and they can determine within seconds to which group of flyers the storks belong.
