  The properties of the thermal Abelian color-magnetic monopoles in the
maximally Abelian gauge are studied in the vicinity of the
confinement-deconfinement phase transition in the lattice $SU(3)$ gluodynamics
and lattice QCD. We compute the density and interaction parameters of the
thermal monopoles. We find that the density of the thermal monopoles $\rho(T)$
jumps up near the transition temperature $T_c$. Additionally we present new
results on the percolation transition in $SU(3)$ gluodynamics which is known to
coincide in gluodynamics with the confinement-deconfinement phase transition.
