I was up at Horicon Marsh a couple weeks ago. 

The following link is a photo of a Great Blue Heron.  What is this behavior?  
The bird held its wings out low and wide for several moments.  In addition, it 
called out several times to other birds to it's right.  Is this an act of 
aggression or a show of dominance?

So, I was on the auto route and just beyond the large parking lot there is a 
pond to the left.  There were numerous Egrets in the area.  I watched several 
picking and eating these slimy little creatures.  Is the meal a leech or some 
worm?

Lastly, along the boardwalk that traverses the pond, there were many swallows.  
But, for a brief moment, the bird shown in the next link rested.  This is the 
best photo I could get before it flew off.  What bird is this one?

Thanks in advance for your comments.
