The bird is showing nicely, at least it did so in the 1:00-2:00 time frame. 
From the visitor center proceed on the something loop trail until you come 
out onto a field. To your left is a line of tree separating two fields.  It 
has been frequenting that line of trees.  This afternoon it was perching 
nicely on  a tangle next to a green bush about 2/3 of the way down the tree 
line.

The bird, by the way, is a young Northern Shrike.  The scalloping is visible 
on the breast and it has a narrow black mask with little white above or 
below.
