• Fig. 1. Nesting territories of Steller’s Sea Eagles (a scheme). Six territories are shown, of which four are active (have an active nest with eggs or nestlings), one is not active and one is no longer in existence
• Fig. 2. The Steller’s Sea Eagle global range and two study areas, «Lower Amur» (Khabarovsky Krai) and «Sakhalin» (Sakhalin Region)
• Fig. 3. Accumulation curves for Sakhalin Island and the Lower Amur, constructed from field data. There are three measures of sampling effort: the number of samples (the number of field seasons), time (the number of field days) and sample volume (the number of inspected nests)
• Fig. 4. Solid lines represent the Bertalanffy model, dashed lines are the Clench model, dotted lines are the Hill model, and long-dashed lines are the Weibull model. Measures of effort are the number of samples (or field seasons), the number of field days, the number of visited nests
