| [occurrence of parasites in indigenous birds of prey and owls]. | in the present paper a general overview on parasites in birds of prey and owls is given. this part is followed by a study investigating the prevalences and species of parasites in free-ranging birds of prey and owls in berlin and brandenburg state, germany. over a one year period, 84 birds of prey and owls of the following species were examined for the presence of endo- and ectoparasites: common buzzard (buteo buteo) (n = 32), kestrel (falco tinnunculus) (n = 20), sparrowhawk (accipiter nisus) ( ... | 2002 | 11852683 |
| pcdds/pcdfs, pcbs, and organochlorine pesticides in eggs of eurasian sparrowhawks (accipiter nisus), hobbies (falco subbuteo), and northern goshawks (accipiter gentilis) collected in the area of berlin-brandenburg, germany. | concentrations of polychlorinated dibenzo-p-dioxins (pcdds), polychlorinated dibenzofurans (pcdfs), polychlorinated biphenyls (pcbs), and organochlorine (oc) pesticides were measured in unsuccessfully hatched eggs of three different kinds of predatory birds: 3 eggs of sparrowhawks, 7 eggs of hobbies, and 16 eggs of goshawks collected in the german region of berlin-brandenburg. using toxic equivalency factors for birds, eggs of hobbies contained mean concentrations of 478 pg teq/g fat and 551 pg ... | 2002 | 11994791 |
| prevalence of trichomonas gallinae in northern goshawks from the berlin area of northeastern germany. | in recent years, the northern goshawk (accipiter gentilis) has colonized suburban and urban areas in berlin, germany, and elsewhere in europe. because of the high proportion of feral pigeons (columba livia f. domestica) in their diet, urban goshawks are suspected to have a high infection rate with trichomonas gallinae. therefore, from 1998 to 2001, we examined 269 nestlings from 90 nests for infection with t. gallinae by culture of swabs taken from the oropharynx and checked their oropharynx for ... | 2005 | 16107664 |
| environmental contaminants in liver and kidney of free-ranging northern goshawks (accipiter gentilis) from three regions of germany. | the northern goshawk (accipiter gentilis) is a top predator in the terrestrial food web of large parts of the holarctic. due to its sedentary nature and well-investigated feeding ecology, it represents the most suitable bird of prey species in continental europe for monitoring environmental pollutants. we analyzed the levels of organochlorine pesticides, polychlorinated biphenyls (pcb), and nonessential heavy metals in organ samples of 62 free-ranging northern goshawks found dead or injured in g ... | 2003 | 12948182 |
