This paper is devoted to the study of the propagation dynamics of a mutualistic model of mistletoes and birds with nonlocal dispersal. By applying the theory of asymptotic speeds of spread and travelling waves for monotone semiflows, we establish the existence of the asymptotic spreading speed
$c^*$, the existence of travelling wavefronts with the wave speed 
$c\ge c^*$ and the nonexistence of travelling wavefronts with 
$c\lt c^*$. It turns out that the spreading speed coincides with the minimal wave speed of travelling wavefronts. Moreover, some lower and upper bound estimates of the spreading speed 
$c^*$ are provided.
