Depicted by the red arrows is the DOOR BRANCH of the H.M.K.T.
It is the preferred perch before entering the nest box. It also is used for hunting or just guarding the entrance.
It is a great perch when the fledglings come out of the nest box. They can jump or practice fly to other branches of the H.M.K.T.
No predators have ever used this perch, it is guarded very well by FK and MK.
