Abstract: | Strange visitors to the pied flycatcher nest-boxes during the brood-rearing period were investigated in the Moscow oblast during 15 seasons. The total amount of visits was 760. Most of the visits (94%) were made by males and 5% and 1% were made by females and young birds with juvenile plumage, respectively. Both bachelor and paired males of various ages were among the visitors. Most of the adult birds and all young ones behaved as ??inspectors??; a part of the visitors tried to feed nestlings. Among them, only nine males and a female were constant ??helpers.?? |
