Differences in the social context of song production in captive male and female European starlings.
Studies on singing behavior in Oscine focus essentially on males and are carried out during the breeding season. Singing in females appears rare and is not well documented. However, females of several species can produce a complex song. Does this lack of data correspond to a real difference in males and females or to a non appropriate context of observation? We studied the vocal and social behavior of captive male and female European starlings during two periods: breeding and non-breeding periods. Our results indicated that females sang mostly in a non-breeding context: their singing behavior was strongly diminished when nestboxes were present in the aviary. Moreover, females sang more frequently when their closest neighbor was a female whereas males sang mostly when they had no immediate neighbor. These results indicate a difference between males and females for the context of song production.
