We present the first search for the weak radiative decays and using a data sample of 980~fb $^{-1}$ collected by the Belle detector operating at the KEKB asymmetric-energy collider. There are no evident or signals. Taking the decays and as normalization channels, the upper limits at 90% credibility level on the ratios of branching fractions ${cal B}(Lambda_c^+ to Sigma^+ gamma)/{cal B}(Lambda_c^+ to p K^{-} pi^+) < 4.0 times 10^{-3}$ and ${cal B}(Xi_c^0 to Xi^0 gamma)/{cal B}(Xi_c^0 to Xi^- pi^+) < 1.2 times 10^{-2}$ are determined. We obtain the upper limits at 90% credibility level on the absolute branching fractions ${cal B}(Lambda_c^+ to Sigma^+ gamma) < 2.6 times 10^{-4}$ and ${cal B}(Xi_c^0 to Xi^0 gamma) < 1.8 times 10^{-4}$ .
