Top o' the Morning

Walking out in Baloo's big field one chilly morning, I saw quite a few birds using the treetops to announce their claim on various territories.
 

 
This cardinal made use of the top branches of a big, grape vine covered autumn olive bush.

 
The red-winged blackbird chose the very tip of a young tree that also had some grapevines trying to overtake it.

 
The poplar was popular with the robin.

 

The pileated woodpecker found a dead oak branch to announce his ownership of a different section at the edge of the field.

Then, he flew off to perch on another corner of his territory to delineate his domain.
