Abstract

Our article deals with the problem of ‘nestlings’ - young adults who postpone the moment of entering adulthood. A brief review of data and research results indicates that delays in undertaking developmental tasks typical of adulthood refer to a professional job, starting a family or a relationship, and gaining independence (not only financially). We discuss cultural, economic and psychological contexts of nestling, and attempt to answer the question whether waiting for adulthood is a global problem or a problem specific to only certain countries or just to Poland. It seems necessary to undertake research on this phenomenon. Nestling ought to be explored not only from the adult child’ perspective but from the parental perspective as well.

Abstract

The population of House Sparrows in most of European cities declined in the end of the XX century (De Laet & Summers-Smith 2007). One of the presumable reasons of this decline is loss of nest sites. The House sparrow is a secondary hole-nester (Anderson 2006) and places its nest in holes of buildings, shrubs and nest boxes. The rate of nest box occupation depends on the location and competition with other species (Anderson T.R. 2006).

The aim of this study was to investigate the rate of nest box occupation by House sparrows in Zielona Góra, Western Poland, which can provide information about the availability of nesting sites.

Abstract

Species-specific features of blackheaded wagtail, Motacilla feldegg Michahelles, 1830, breeding biology were identified in the Rostov oblast of Russia. A tendency to current species range shift is traced.
