The report concerns a married couple who were repeatedly invaded by pigeon fleas (Ceratophyllus columbae) over a period of 2 months. The source of the fleas was a pair of breeding feral pigeons (Columba livia). The birds' nest was located in the attic immediately above the couple's apartment, and the fleas found their way along an unsealed heating pipe. The people encountered up to 40 bites per night. With invasions repeated almost every night, the man gradually developed an allergic urticarial reaction. The most traumatic experience for the couple, however, was to learn that they were invaded by fleas (initially, they had presumed they were bothered by mosquitoes). This information resulted in severe psychological distress with phobic reactions and insomnia. Despite the successful removal of the fleas and the pigeons that were source of the pest, parasitophobia of the man persisted over the following 4 months. This case is discussed from the broader aspect of health risks related to feral pigeons and animal fleas. Also summarised are previous observations on people invaded by pigeon fleas.

The aim of this study was to compare ecophysiological basis for developing feral pigeons (Columba livia f. urbana) in various environments of Northern Poland. We examined heavy metals contents, lipid and protein peroxidation, antioxidant enzymes activity in individuals growing and feeding in the different polluted regions. Pigeons from urban area possessed high maintenance of cadmium in the blood, but low lead in comparison to birds from rural area. Our results suggest that increased level of heavy metals (Pb and Cd) in the blood of pigeons from different regions of Northern Poland tended to affect negatively initiate lipid peroxidation and increased oxidative modified protein content. Our results suggest that increased level of oxidative stress in birds is dependent upon environmental pollution. Statistical analysis (ANOVA and GLM) has shown that colony localization (urban or rural areas) modified antioxidative defense system, level of lipid and protein peroxidation, and blood total antioxidant activity.
