I'm wondering if this pair of osprey are planning a big family, because they keep increasing the size of their nest.
Every time I have gone there in the last week,  the nest keeps getting bigger.  While I was there tonight, I saw the osprey go into the water and come up with what I thought was a fish.  But, after looking at the photo more closely, I think he was carrying a big scoop of mud. 
Next, he went out and found this big branch to add to his new home!  He carefully placed the branch securely, before he took a rest.  I love watching them!  Can't wait to see what they do next.
