Abstract

The differences in morphology and age between single and paired males of an urban population of the European Blackbirds (Turdus merula) were studied in Żeromski park in the city of Szczecin (NW Poland) spanning 11 breeding seasons since 1998. The proportion of single to paired males in different age groups was established. Also, morphology features like the length of tail, wing and tarsus of 45 single males and 475 paired males were collected. We found that old males (after second year of life) formed pair bonds more often than the young males (in their second year of life). The probability of being a paired male in case of young males increased along with the tarsus length.
