| dcterms.abstract | In the study conducted during the two-year period (2017 - 2018) the cause of death of
certain protected and strictly protected wild bird species from the territory of Vojvodina
was analysed. During this period, 57 wild birds were brought for post-mortem
examination (a total of 9 protected species) to Scientific veterinary institute "Novi Sad".
A detailed macroscopic examination of all birds was carried out, while in certain cases
samples were taken for microbiological, molecular and toxicological analyzes.
Most of the examined wild bird carcaces were in good preserved state and condition. The
most dominant pathomorphologic changes observed in the organs of the gastrointestinal
system included hyperemia, thickening and edema of the mucous membrane of the
intestines with haemorrhages. Escherichia coli and Proteus spp. were determined by
bacterial analysis of the intestine, while the coccidial oocysts were found by
parasitological examination. A large infestation of adult forms of nematodes was found in
cormorants, which were localized primarily in the mucosa of the proventriculus as well as
in the lumen of the intestine and esophagus. In the crop and gizzard of protected eagle
species, partially macerated content of pink color was determined. Toxicological analysis
of the susceptible content showed the presence of carbofuran poison, indicating an
alimentary intoxication. The most frequent changes in the liver were in the form of
perihepatitis and the occurrence of focal necrotic fields. The most common macroscopic
changes in organs of respiratory system included congestion and haemorrhages in the
lungs. An infraorbital sinus edema and purulent sinusitis have been identified in two birds.
Macroscopic examination of the heart showed no pathological changes in most of the
birds. Kidney changes in the form of edema and congestion were observed sporadically.
Bone fractures with extensive subcutaneous hematomas, as well as the finding of large
blood clots in the abdomen indicated traumatic injuries in several bird species. A buckshot
was found in three birds indicating wounding by firearms, and bone and muscle ruptures
were detected at the necropsy.
Based on the above-mentioned pathomorphological changes and the results of laboratory
analyzes, it can be concluded that numerous etiological factors contribute to mortality of
wild birds. However, the results of this preliminary study indicate that the anthropogenic
factor is certainly one of the common causes of death of protected wild bird species and
in this regard, certain measures need to be taken to prevent people's illegal activities and
the negative impact on wild bird population. | En |
