Nests???

 Out for a sunday walk this afternoon we came across this tree.  I have seen nests in trees before but this one seems to be the best one yet.  Look at all the nests.  I'm assuming they are nests.  I'm no expert but they sure look like nests to me.


Have you ever seen a tree like this before with so many nests?


If you have an idea about it let me know I'm curious.


Ok till next time
