Analysis of the Influencing Factors on Nesting Investment of Japanese Tits
Secondary cavity-nest birds are an indispensable part of forest ecosystems,and studying the investment of par-ent birds in nest during the breeding period is of great significance.2019-2022,we used artificial nest boxes,taking nest material quality and the proportion of hairy nest material quality as indicators,to investigate the relationship between the arti-ficial nest box setting,nest material composition,breeding period and the reproductive investment of Japanese tits(Parus minor)in Zuojia Nature Reserve,Jilin Province.The results showed that Japanese tits tended to select small entrance size(2.8 cm)nest boxes(68.35%)with high quality of input nesting material.The orientation of nest entrance had no signifi-cant effect on nesting material quality,but had significant difference on amount of hair use.The percentage of hair quality in northwest orientation was significantly higher than that in southeast orientation(p<0.05),and the percentage of hair quality in the small entrance size nest boxes in the southeast orientated nests was significantly higher than that in the large and medium entrance size nest boxes(p<0.05),while the opposite was true in the northwest orientated nests,where the per-centage of hair quality in large and medium entrance size nest boxes was significantly higher(p<0.05)than that in small entrance size nest boxes,but there was no significantly different in the percentage of hair quality in two orientated small entrance size nest boxes.The hair usage in the first brood was significantly higher(p<0.05)than that in the second brood during the breeding periods of Japanese tits.The research revealed that the orientation of nesting box,the entrance sizes,the percentage of hair quality in nesting material and the breeding period can affect the nest nesting input of Japanese tits.This bird can quickly change breeding strategies and breed offspring in suitable environment during the breeding period.
