We first give a brief overview of the charmed baryon spectroscopy and discusstheir possible structure and spin-parity assignments in the quark model. Withthe new Belle measurement of the widths of $\Sigma_c(2455)$ and$\Sigma_c(2520)$ and the recent CDF measurement of the strong decays of$\Lambda_c(2595)$ and $\Lambda_c(2625)$, we give updated coupling constants inheavy hadron chiral perturbation theory. We find $g_2=0.565^{+0.011}_{-0.024}$for $P$-wave transitions between $s$-wave and $s$-wave baryons, and $h_2$, oneof the couplings responsible for $S$-wave transitions between $s$-wave and$p$-wave baryons, is extracted from $\Lambda_c(2595)^+\to\Lambda_c^+\pi\pi$ tobe $0.63\pm0.07$. It is substantially enhanced compared to the old value oforder 0.437. With the help from the quark model, two of the couplings $h_{10}$and $h_{11}$ responsible for $D$-wave transitions between $s$-wave and $p$-wavebaryons are determined from $\Sigma_c(2880)$ decays. There is a tension for thecoupling $h_2$ as its value extracted from $\Lambda_c(2595)^+\to\Lambda_c^+\pi\pi$ will imply $\Xi_c(2790)^0\to\Xi'_c\pi$ and$\Xi_c(2815)^+\to\Xi_c^*\pi$ rates slightly above the current limits. It isconceivable that SU(3) flavor symmetry breaking can help account for thediscrepancy.
