Ladoga Ornithological Station is the main site of the field study of the Lab.
It was in 1960-1966 when the Biology Department of the Leningrad University initiated an extensive research focused at bird migration in the Leningrad region. As a result of this work, which involved many researchers from the Department staff, the entire Ladoga Lake coast
was explored. Gumbaritsy, an old village, appeared to be a place of special interest. Migration both of land birds and of waterfowl there is very intensive and, importantly, the topography of this place allows an opportunity for mass trapping of birds. Finally, two big Rybachy-type traps were erected in 1968, which was the result of joint efforts of ornithologists from the Leningrad University and Karelian Research Centre of Russian Academy of Science. The traps basically became a part of the landscape at Svir Bay coast. In addition, in 1979 the researches of Karelian Scientific Centre started their own observation site at Majachino, 13 km apart from Gumbaritsy. The simultaneous work of the two stations gave a unique opportunity to obtain a comparative data on the territorial behaviour, migration routes and wintering grounds of many species. The research staff of Gumbaritsy station in late 70s had done much for the organization of protected area at Svir Bay. This resulted in the establishment of Nizhne-Svirsky State Reserve at the Southern part of Ladoga Lake in 1980. The observation site, therefore, occupies a plot which is a part of this area. In 1998 Gumbaritsy observation site was awarded the official title of Ladoga Ornithological Station (LOS) of Biological Research Institute of the St.-Petersburg State University.

Research work The scientific work at LOS involves bird banding as well as studies focused on bird migration, moult, breeding and other aspects of bird ecology. Developing effective methods for bird trapping and for keeping them in captivity is also an essential part of the work. Every year up to 20 000 birds and trapped, ringed, measured and weighted at the station. The state of the feather coat, fat reserves is also recorded in the bulk of the birds. Scientific data obtained at LOS provided a background for four Doctoral dissertations and 20 PhD theses. In addition to this, more than 300 scientific papers and 5 monographic books have been published so far. It is also very important that dozens and dozens of graduate and PhD students have improved their field work skills while working at the station.
The data on ringing are stored in the computerized Data Bank of the Laboratory of Avian Ecology and Bird Protection.
