An Evaluation of 4-aminopyridine for Dispersing Winter Blackbird Roosts in Colorado
INTRODUCTION Blackbirds and starlings (Sturnus vulgaris) often establish large winter roosts in areas where their presence is objectionable because of economic, public health, and nuisance reasons. Several techniques are available for alleviating roost problems, including habitat manipulation, roost dispersal with mechanical and pyrotechnic devices (Mott et al 1978), and, where necessary, direc...
متن کاملCommunal Starling Roosts: Implications for Control
Roosting behavior is common to most avian pests of agriculture. Movements from highly aggregated distributions in roosts to highly dispersed distributions on foraging grounds determine pattern and severity of avian pest problems. This research seeks an understanding of how roosting behavior influences the dispersion of avian agricultural pests and the damage they cause. My focus is on why birds...
متن کاملDoes the roosting behavior of birds affect transmission dynamics of West Nile virus?
The potential role of many urban passerine birds in the transmission of West Nile virus (WNV) is well-documented by studies on host competency, seroprevalence in wild birds, and identification of vector blood meal source. In contrast, the impact of bird behavior on transmission dynamics is largely unexplored. Bird roosting (perching) behavior may be a critical component regulating WNV transmiss...
متن کاملRoosts and migrations of swallows
— Swallows of the north temperate zone display a wide variety of territorial behaviour during the breeding season, but as soon as breeding is over, they all appear to adopt a pattern of independent diurnal foraging interleaved with aggregation every night in dense roosts. Swallows generally migrate during the day, feeding on the wing. On many stretches of their annual journeys, their migrations...
متن کاملOdour cues influence predation risk at artificial bat roosts in urban bushland.
Odours that accumulate from roosting can attract predators and increase predation risk. Consequently, selection should favour strategies that allow prey to evade detection by predators, including changing roosts. Insectivorous bats that roost in tree hollows regularly switch roosts and roost in different sized groups, strategies that would alter the accumulation of roost odours and are hypothes...
