Abstract: The experiments of six different densities of artificial asphalt felt nest-boxes areas showed that the distribution patterns of laying nest-boxes of great tit (Parus major) deviated from random expectation in the direction of uniformity (R=1.1 to 1.4), as the same as the distribution patterns of established nest-boxes (R=1.2 to 1.6). The correlation between the densities of laying nest-boxes and the densities of established nest-boxes was not obvious (r=0.30). The suitable distance between established nest-boxes was about 30 to 50 m.It is easy to make asphalt felt nest-boxes and its cost is lower than that of the wooden nest-boxes The process of making asphalt felt nest-boxes was introduced and its suitabilities for great tits were discussed in the aspects of the average clutch-size and the survival of eggs and nestlings of great tits.
