Mantled Guerezas (from the Archive)

This is really kind of a crummy photo, but seeing these two Mantled Guereza monkeys (Colobus guereza) leaping from tree to tree in the Bwindi Impenetrable Forest Reserve (see Bwindi Impenetrable Forest) with their long white mantle trailing behind was breathtaking. 

...faces among the leaves,
being ears and eyes of trees,
soft hands and haunches pressed on boughs and vines

Then - wha! - she leaps out in the air
the baby dangling from her belly,

they float there,

-she fetches up along another limb - and settles in.
