  In this note, we provide a bijection between a new collection of words on
nonnegative integers of length n and Dyck paths of length 2n-2, thus proving
that this collection belongs to the Catalan family. The surprising key step in
this bijection is the zeta map which is an important map in the study of
q,t-Catalan numbers. Finally we discuss an alternative approach to this new
collection of words using two statistics on planted trees that turn out to be
closely related to the Tutte polynomial on the Catalan matroid.
