In an environment which is in constant motion, the adaptive capacity is one of the primordial characteristics of the living organisms. Many researchers have studied this issue, but so far the subject remains open. Currently, there are 15 species of birds of prey which can be encountered in Moldova. We were able to confirm the breeding of 11 species out of these 15. During the cold season of the 2012-2015 years there were checked approximately 5,000 hectares of forest and 20,000 ha of open land in different parts of the country, in order to identify breeding raptors. These periods were chosen because the visibility in closed and semi-open land is higher. Later in the same years, but during nesting season (April to June), we checked again the before-mentioned places in order to determine the occupancy of the nests. In total, we identified and recorded using GPS devices 76 nests, 39 of them being occupied by various species of this order during our second check.
