I arrived late today, just before 9 AM.  The action was slow in the 
beginning, but soon picked up as the temperature rose.  Lots of birds, 
but not a lot of diversity.  Best birds were an adult Bald Eagle (the 
first I've seen there - it flew right over my head only 50-75 feet up - 
binocs not required) and two Red-tailed Hawks.

One of the RTHAs was extremely pale, the tail much lighter than the 
Krider's illustrated in Sibley.  At first I thought it was a harrier 
because when viewed from the side while flying, the rump looked 
brilliant white.  Eventually it identified itself by a typical RTHA 
screech, whereupon its friend (mate?) took off from the ground near me. 
  The friend was a typical eastern adult RTHA.  The only puzzling thing 
about the pale RTHA was that its throat was brown, unlike the Krider's 
illustration.

Can somebody tell me how (un)common Krider's RTHA is around here?  The 
only places I've seen them are southern Manitoba and just west of Houston.

Also, how common are Bald Eagles at Blue Mash?
