Springtime in Longmont: Grackles have returned

It must be Spring because I heard (that unmistakable rusty-hinge call) a common grackle for the first time this morning in suburban Longmont. Thirteen days later than last year when I saw one on March 15. As reported here, I noticed them fully vacated right around Halloween; a break of about five months (~149) days from Colorado

Let's see how a few of them have spent their winter vacation in Texas:

• Ft. Worth Hires Hawks to Solve Pesky Grackles
  
  
• Austin Grackle Invasion
  
  
• Grackles Fill the Sky in Waco
  
  

In other words, just their normal holiday down south!
