In the world-wide literature the role of predators and food shortage are considered as responsible for mortality of eggs and nestlings. In synantropic altricial hole-nestling birds such as sparrowsPasser domesticus (L.) andPasser montanus (L.) the predation plays unimportant role and in spite of this, mortality of eggs and nestlings can exceeded 50%.

Synanthropic sparrows in Poland and the Czech Republic were tested for Toxoplasma gondii antibodies by an indirect fluorescent antibody test (titre>/=10). T. gondii antibodies were demonstrated in 12.3% of 227 house sparrows (Passer domesticus) and 4.9% of 41 tree sparrows (Passer montanus).
Sparrows from central Poland were examined by a hemagglutination-inhibition test (titer > or = 20) for the presence of antibodies to arboviruses, between 1995 and 1996. In house sparrows (Passer domesticus) (n = 179), antibodies to Sindbis, West Nile, tick-borne encephalitis, Tahyna, and Calovo viruses were detected at seroprevalences of 1.1%, 2.8%, 1.1%,(More)
Animals can estimate breeding habitat quality by monitoring social information provided by the behaviours of others. While it is accepted that the value of public information erodes with distance from the source of information, the spatial and temporal ecology of public information acquisition and use is not well understood.

From 1995 to 1997, house sparrows (Passer domesticus) (n = 273) from suburban area close to Kunín in the northeastern part of the Czech Republic were examined by using a(More)
