Diet and the conduct of Tengmalm's owl, in two different food situations,were compared.
Supply to mice was greater in Czechore-Mountains Than near the City Kauhava in West-Finland
With cameras were the numbers of food services and the nature of prey brought, to the nest a great topic.
In Tsjehie there were 990 turns, with food, This in six breeding places, In Finland 1.649 to nine breeding places.
In the Ore-mountains were mainly forest mice also burrow mice put on for the young birds, wile in the area of Kauhava barrow mice and shews were feed to the young birds.
The prey in Finland were considerably smaller than the preys in the ore-mountains ,but a greater number of higher food turns, the study turns to a equivalent two biomass.
This is translated into a similar number of young birds flown from the nest, this in Czech and Finland.
This study proves once again that the food supply is also very important for this species, also the habitat and management, this are living proof also the success of a good hatch once again the proof that this study also others are a of a great need.
