Feral Pigeons: Problems, Dynamics and Control Methods
Feral pigeons are birds now largely present with naturalized populations all around the world (Lever, 1987). The Rock Dove (Columba livia), which is their ultimate ancestor, was originally present in coastal and inland cliffs of central and western Palearctic and in the northern Ethiopian regions, as well as in those of the Indian subcontinent (Goodwin, 1983). These wild populations gave rise t...
متن کاملEffectiveness of Gel Repellents on Feral Pigeons
Millions of feral pigeons (Columba livia) live in close association with the human population in our cities. They pose serious health risks to humans and lead to high economic loss due to damage caused to buildings. Consequently, house owners and city authorities are not willing to allow pigeons on their buildings. While various avian repellents are regularly introduced onto the market, scienti...
متن کاملEnzymatic Digestion Pattern of Varicella Zoster Virus ORF38 and ORF54 in Chickenpox Patients Using RFLP Technique
Background: Varicella zoster virus (VZV) causes chickenpox in children and zoster (zona) in the elderly. Using RFLP-PCR method for detection of VZV specific SNPs ORF38, 54 and 62 could distinguish the profile of VZV isolates. The aim of this study was to investigate enzymatic digestion pattern of VZV ORF38 and ORF54 in chickenpox patients using RFLP technique. <b...
متن کاملShivering and digestion-related thermogenesis in pigeons during dark phase.
The pigeon's main source of regulated heat production, shivering, is especially likely to be used for thermoregulation during the dark phase of the day when there is little heat from locomotor activity. However, food stored in the pigeon's crop is digested during the night, and digestion-related thermogenesis (DRT) will provide heat that should decrease the need for shivering to maintain body t...
متن کاملUrban feral pigeons (Columba livia) as a source for air- and waterborne contamination with Enterocytozoon bieneusi spores.
This study demonstrated that a person with 30 min of occupational or nonoccupational exposure to urban feral pigeons, such as exposure through the cleaning of surfaces contaminated with pigeon excrement, could inhale approximately 3.5 x 10(3) Enterocytozoon bieneusi spores and that 1.3 x 10(3) spores could be inhaled by a nearby person.
