For a week now there have been squawks in the sky around here as the sandhill cranes announce their return.  Can spring be far behind these birds as they return to Wisconsin wetlands?  I'd not seen them until yesterday.  Driving around I saw a couple staking out some marshy area in a corn field.  Doubt they'll nest there but still nice to see them scoping out the neighborhood.  Gave me a chance to use my 300mm Nikon lens on the subject I purchased it for!
