We give a geometric classification of regular ends with
constant mean curvature $1$ and finite total curvature,
embedded in hyperbolic space. We prove that each such end is
either asymptotic to a catenoid cousin or asymptotic to a
horosphere. We also study symmetry properties of constant mean
curvature $1$ surfaces in hyperbolic space associated to
minimal surfaces in Euclidean space. We describe the constant
mean curvature $1$ surfaces in $\hi3$ associated to the family
of surfaces in $\m3$ that is isometric to the helicoid.
