Recent results on decays of the charmed strange pseudoscalar meson, the {ital D}{sup +}{sub {ital s}}, are presented. The data were obtained in Fermilab photoproduction experimental E691. Topics discussed include: a probe of the weak annihilation mechanism by studying the decays {ital D}{sup +}{sub {ital s}}{r arrow}{rho}{pi}{sup +} and {ital D}{sup +}{sub {ital s}}{r arrow}{omega}{pi}{sup +}; an observation of the decay {ital D}{sup +}{sub {ital s}}{r arrow}{ital f0}(975){pi}{sup +}; two independent measurements of {ital D}{sup +}{sub {ital s}}{r arrow}{eta}{pi}{sup +}; comments on the vector-vector decays {ital D}{sup +}{sub {ital s}}{r arrow}{phi}{rho}{sup +} and {ital D}{sup +}{r arrow}{ital {bar K}}{sup *0}{rho}{sup +}; and an accounting of measured {ital D}{sup +}{sub {ital s}} decays.
