Vulture watching Sun. Coincidence ???

I have probably posted one or two of these pictures before.
I have, however, not placed them in such proximity to each other
and have not pointed out this peculiarity:

The Vulture seems to be looking at the still distant Sun.

His head is directed to his far left.

This close-up shows the direction of the Vulture's head 

more clearly.

The Sun has come considerably closer to the tree

and the Vulture's head is following the Sun's path.

This cut-out again (below) shows the Vulture's head

clearly directed to the new location of the Sun.

The Vulture is peering down at the Sun,

which now has moved directly behind the tree.

once again the close-up shows the Vulture's head more clearly.

What is this then?

Is it a Vulture interested in the Sun's precise location?

Or is it simply a funny coincidence?

You be the Judge!
