The recent results from the Bonn-Gatchina group are presented and discussed. The analysis of the new data on the η and η′ photoproduction off proton firmly confirms the existence of three nucleon resonances with masses around 1900 MeV. The combined analysis of the data on the kaon proton collision reactions indicates the presence of new states which were missed in the analysis of the separate data sets.
