Tulip Poplar which is a high risk of hazard (HRH).

First, the tree is over a road often traveled (target).

Notice that the branch is competing in size with the trunk.  Branch collars are unique in the manor they can support large cantilevers.  However, when the branch grows to equal size with the trunk, the unique feature is compromised.  Take a closer look at the size in the next picture.

 

 

 

 

 

 

 

Second, when symplast maintaining branches bend abruptly upward or downward where tips of large branches were cut off - tipping -   the tree is a high risk of hazard.  

This tree is a mature beautiful tree.  It's important to properly diagnose high risk of hazard trees rather than removing trees that do not pose a risk out of the ignorance of tree biology.  I would recommend removing this tree or moving the road.  There are people in the world that have moved houses, roads and other targets rather than removing the tree.  One group is called the "Outdoor Circle".  They are some of the finest people in the world. 

Removing the two questionable branches would be over pruning.  I would recommend removing the top and placing the trunk back into the woods as a nurse log.  It would help the health of the system.  Wood plays a key role in soil, stream and river health - "One Reference on streams".
