A Remark on Neutrino Oscillations Observed in Kamland Experiment

It is demonstrated that the observation of neutrino oscillations in the atmospheric (K2K) neutrino experiments and unitarity of the mixing matrix implies that disappearance of the reactor $\bar\nu_{e}$'s discovered in the KamLAND experiment is due to $\bar\nu_{e}\to \bar\nu_{\mu}$ {\em and} $\bar\nu_{e}\to \bar\nu_{\tau}$ transitions. At $\theta_{23}=\pi/4$ the probabilities of these transitions are equal.
