2 Nests for 2sDay

It's 2sDay ... the day for sharing some photos I've taken with 2 of the same thing in it.

Just look at these 2 big nests that I saw in the same tree on one of my walks down by the bay.  They are in the trees right by the water's edge.

 Here are the same 2 nests taken from the opposite side.  They are 2 big, deep nests that make me think they are squirrel nests.  Yet on my walks I really don't see a lot of squirrels by the water.

I wonder who lived in these nests or who still lives in them.  I'll be checking them out on future walks to see if I can see any birds or animals in them.

 Do you have any thoughts who might of built these nests? Thanks for visiting today. It's a rainy 2sDay here.  Hope you are enjoying some sunshine where you are.
