Mackinac Straits Raptor Watch 3/16/2017

  March is the beginning of raptors passing through Michigan from their overwintering sites to their summer breeding grounds. Around the middle of this month eagles and some large hawks make a significant push along their favored routes.  As they pass north through the lower peninsula they are funneled toward the Straits of Mackinac in order to navigate to the UP and points beyond. 
  Today I traveled to the Mackinac Straits Raptor Watch in Mackinaw City in hopes of observing this yearly phenomena. 

Here are some photos taken from the watch location.
   More than 260 Golden Eagles have been counted in the month of March in each of the last two years.

   This Bald Eagle was determined to be one of a local pair.

  Finally an update on the planet Venus.  We are just 9 days from Venus moving from the evening sky to the morning sky.  It now displays a 4% illuminated crescent the spans almost on arc minute in diameter (for reference the Moon is 30 arc minutes in diameter).
