Between 2012 and 2019, 6523 raptors and owls (30 species) were ringed in Slovakia. The most abundant was the common kestrel (2811 individuals), then the western marsh harrier (664) and saker falcon (517). The proportion of nestlings among all the ringed individuals was 84.4%. In the given period, 340 recoveries of raptors and owls (23 species) were recorded in the ringing station database. This number included 160 recoveries of individuals colour-marked and also recovered in our territory. There were 83 recoveries of birds ringed in Slovakia and resighted abroad. The last 97 recoveries were of individuals ringed abroad and recovered in Slovakia. In summary, most of the recoveries (of all types) were of Eastern imperial eagle (62 recoveries), then red-footed falcon (51) and common kestrel (43). Most of the recovery circumstances were ring reading (44% in total), recaptures (15%) and findings of bird cadavers. Regarding raptors or owls, collisions with vehicles (5%) and electrocutions (5%) were frequent causes of their deaths.

The paper shows the results of experiments focused on the analysis of sustainability of a quality work team in an IT organization. The analysis has been carried out based on the evaluation of the new real dates. Data consists of competences and direction of the strategy of individual specialists, as well as the strategy of the IT team as a whole. The principles of the SWOT analysis and of confrontational matrix have been used to evaluate the strategy and focus of individuals. The next step of the solution assumes the use of the principles of artificial intelligence in the process of solving relations within organizations.
