Territorial male songbirds have the ability to discriminate between the songs of their neighbours and those of strangers and for a few species it has been shown that they maintain this ability from one breeding season to the next. To better understand the acoustic basis of this long-term discrimination ability we studied song stability across two breeding seasons in a migratory songbird with high inter-annual return rates and territory stability, the black redstart, Phoenicurus ochruros. Strophe repertoires of 14 males (≥2 years old) were stable from one breeding season to the next and high strophe sharing occurred for males within the same group of houses or hamlets (81%) in contrast to only limited sharing between different hamlets (15%). However, subtle differences exist between the renditions of the same strophe sung by neighbouring males and these differences equally show an inter-annual stability, providing an acoustic basis for long-term discrimination abilities. Playback tests showed the existence of a strong dear-enemy effect: males reacted less aggressively to the familiar, often shared song of a neighbour than to a stranger unshared song and this pattern was maintained when birds returned from migration one year later. We discuss on one side the possible mechanisms leading to the observed patterns of song sharing and on the other side the significance of stable vocal signatures for neighbour recognition.

AbstractSexual conflict over parental care can be mediated through differences in male and female overall feeding rates, brood division or both. At present, it is not clear whether post-fledging brood division occurs due to sexual conflict over parental investment or is due to bi-parental cooperation, e.g. increase offspring fitness. We provide evidence suggesting that brood division in the black redstart, Phoenicurus ochruros is due to sexual conflict. Males and females had similar feeding contributions during the nestling stage, which is common for most passerine species. After fledging, each parent showed long-term feeding preferences for particular chicks within the brood. In most cases (74%; 17/23) both parents provided care but males tended to feed less fledglings than females did and in about a quarter of cases (26%; 6/23) females fed the whole brood by themselves. The relative amount of male to female post-fledging feedings showed a significant negative relationship with the proportion of fledglings cared for exclusively by the male. These results suggest (1) a close link between the amount of parental care and brood division; (2) sexual conflict can be mediated through brood division; (3) female redstarts appear to loose this conflict more often than male redstarts, with in the extreme cases males showing post-fledging brood desertion. A literature review shows brood division to occur in at least a dozen of songbird species but male black redstarts have the lowest relative post-fledging parental investment, expressed either as feeding rates or number of chicks in care.

On the basis of literature and collection materials, as well as photographs with geo-referencing from various sources, the actual breeding range of the Black Redstart Phoenicurus ochruros (Gmelin, 1774) was compiled. For the Asian part of the range, a probabilistic model is constructed for the geographic distribution of the species by the maximum entropy method, which is used to refine the range in some of its regions. Based on the collection materials of the Zoological Museum of the Moscow State University (Moscow), Zoological Institute of the Russian Academy of Sciences (St. Petersburg) and Institute of Zoology of the Republic of Kazakhstan (Almaty), a comparison of the breeding plumages of adult male Black Redstarts from the Asian part of the range was carried out. The revealed differences made it possible to describe a new subspecies from Altai, Tuva, Northern China and Western Mongolia – Phoenicurus ochruros murinus Fedorenko subsp. nov., which is distinguished from the neighboring Turkestan subspecies Ph. o. phoenicuroides by the absence of any contrast in the colour of the head, nape and back; all of which are concolourous dark grey. From Latin, the subspecies name “murinus” is translated as “mouse grey”, which characterises the colour of the upperparts of the bird. A revision of other subspecies of the Asian Black Redstart group was carried out and a map of their distribution was compiled.
