Fecal samples originating from 15 Eurasian griffon vultures were collected during June 2012 in the territory of special nature reservation Uvac and examined for presence of enteric bacteria ...Escherichia coli and Salmonella spp. Salmonellas were isolated from five samples (33.3%) and serologically typed as Salmonella enterica subsp. enterica ser. Veneziana. E. coli was isolated from four samples (26.6%). Antimicrobial susceptibility testing revealed resistance to one and more antibiotics only in E. coli isolates.
Na otoku Cresu ovčarstvo je stoljećima bilo temeljna gospodarska djelatnost koja je čovjeku omogućila opstanak. Usporedno je upoznavao i sve ostale čimbenike toga područja pa je tako gospodarenje ...ovcom značilo i dijeliti otočki krajolik s bjeloglavim supom (Gyps fulvus). Pretpostavljamo da usputnim promatranjem te upečatljive ptice čovjek prepoznaje i neke obrasce njezina ponašanja. Ta znanja su se prenosila generacijama usmenom predajom. Isto tako se i odnos prema ptici vremenom nije bitno mijenjao i možda bi ga mogli opisati kao nekakav oblik simbioze. Postupno zamiranje broja ovaca jedan je od razloga i za smanjenje broja supova pa tu ugroženu pticu ornitolozi krajem sedamdesetih godina prošloga stoljeća počinju sistematično istraživati. Prisutnošću u različitim medijima svijest i znanja utkani su u recentni odnos prema tim pticama i suživot s njima. Rezultati znanstvenih istraživanja u određenoj mjeri usmjerili su rad u lokanoj upravnoj te turističkoj zajednici. Stvaranjem novih elemenata baštinskoga identiteta prostora, koji su jako zanimljivi i novim turističkim, ekološkim, ekonomskim, socijalnim i drugim kretanjima djeluje se i na oblikovanje odnosa. Spektar različitosti tih odnosa vidljiv je na individualnoj razini, ali i unutar geografskosocijalno- ekonomskih cjelina otoka.
Supplemental feeding is increasingly used to support vulture populations threatened by declining food resources. As the practice moves from a stopgap procedure to a management technique, information ...is needed on the effects of variations in feeding regime on vulture behavior. We provided food to Egyptian vultures (Neophron percnopterus) in the Negev Desert, Israel, under 2 regimes. A regular feeding station (RFS) was stocked daily with 5-10 kg of chicken carcasses, and an irregular feeding station (IFS) was stocked approximately twice monthly with 20-350 kg of livestock carcasses. At the RFS, numbers peaked at 20-30 birds; flock size at the IFS peaked at 30-40 birds. Adults feeding on chickens could dominate individual carcasses and fed in higher proportions than younger birds. Large carcasses and scattered scraps at the IFS could not be defended by individuals, and adults did not feed preferentially. Small, daily food deliveries favored adults and resulted in higher proportions of flocks feeding. Large, infrequent deliveries did not favor any age class; however, infrequent food deliveries may not provide sufficiently regular food for adults feeding young. Smaller competing scavengers at the RFS did not exclude Egyptian vultures from food. At the IFS, large mammals briefly excluded vultures but often improved access to food by tearing open carcasses. Eurasian griffons (Gyps fulvus) at the IFS excluded Egyptian vultures and consumed most of the available food. Eurasian griffons did not feed on chicken carcasses; hence, small carcasses can be used to feed small vulture species preferentially when species that specialize on large carcasses are also present.
