  We study the flocking model introduced by Vicsek in the "coarsening" regime.
At standard self-propulsion speeds, we find two distinct growth laws for the
coupled density and velocity fields. The characteristic length scale of the
density domains grows as $L_{\rho}(t) \sim t^{\theta_\rho}$ (with $\theta_\rho
\simeq 0.25$), while the velocity length scale grows much faster, $viz.$,
$L_{v}(t) \sim t^{\theta_v}$ (with $\theta_v \simeq 0.83$). The spatial
fluctuations in the density and velocity fields are studied by calculating the
two-point correlation function and the structure factor, which show deviations
from the well-known Porod's law. This is a natural consequence of scattering
from irregular morphologies that dynamically arise in the system. At large
values of the scaled wave-vector, the scaled structure factors for the density
and velocity fields decay with powers $-2.6$ and $-1.52$, respectively.
