  We provide new evidence that the holographic dual to a strongly coupled
charged Fermi Liquid has a non-zero fermion density in the bulk. We show that
the pole-strength of the stable quasiparticle characterizing the Fermi surface
is encoded in the spatially averaged AdS probability density of a single
normalizable fermion wavefunction in AdS. Recalling Migdal's theorem which
relates the pole strength to the Fermi-Dirac characteristic discontinuity in
the number density at $\ome_F$, we conclude that the AdS dual of a Fermi liquid
is described by occupied on-shell fermionic modes in AdS. Encoding the occupied
levels in the total probability density of the fermion field directly, we show
that an AdS Reissner-Nordstr\"{o}m black hole in a theory with charged fermions
has a critical temperature, at which the system undergoes a first-order
transition to a black hole with a non-vanishing profile for the bulk fermion
field. Thermodynamics and spectral analysis confirm that the solution with
non-zero AdS fermion-profile is the preferred ground state at low temperatures.
