Asters or What to look for in September/October

My gosh, I’m late!  I forgot all about writing a phenology for September and now the month is nearly gone!

To make up for this omission, here’s a backward glance at what we missed in September and a look ahead into October.  At this time of year we can expect to see:

  • The nighthawks left by early September.  Chimney swifts are gone by early October.
  • Warblers and thrushes pass through in September.  Look for duck migration in October.
  • Watch for an increase in the number of crows and starlings.
  • The most numerous species at hawk watches changes from broad-winged hawks in September to sharp-shins and red-tails in October.
  • Asters and goldenrod are still in bloom.  I have asters in my back yard that don’t fully bloom until October 1.  Here they are – and it’s almost October.
  • “Hitch hiker” seeds are everywhere.  Burdock, beggar tickseed and tick trefoil grab onto pants and socks.
  • In September, even before the trees and shrubs begin to change color, they lose some leaves and the canopy thins out.
  • Watch for maximum fall color around Columbus Day.

Unlike me, Chuck Tague has kept up with the season.  Read his early and late September phenologies and the almanacs on his blog.
