The Commission's consideration require reports of observations of faunistically important species, i.e. those whose records are relevant for our knowledge of the national avifauna and alterations occurring in it. The current state of our knowledge is reflected in the list of the national avifauna. According to the general rule, liable to verification are:

- first occurrences of hitherto not recorded species (subspecies);
- first broods of hitherto non-breeding species (subspecies);
- records of species and subspecies specified in the tables below.

Records of escapes - except Canary Serinus canaria, Budgerigar Melopsittacus undulatus, and Cockatiel Nymphicus hollandicus - are also liable to verification. An observation of any species which is unusual in the light of the present knowledge may be reported, too.
