Nesting Blue Bird's.

I've been watching the

Blue Bird Box for a while,

I believe there has been

one sitting and now this is

the second. There are 4 eggs 

when I checked yesterday.

Blue Bird's are very tolerant of humans.
Inspecting the nest box doesnt seem to
bother them. I usualy check several times
during each nesting.

I sometimes open the Box and take photos
of the inside of the nest, and eggs.
I may do that later, but not just yet.
I enjoy watching the progress of the nesting.
