Birds attracted to citys waste landfills represent a significant hazard and additional inconvenience to people. It is necessary to understand not only the reasons for which birds enter the given territory, but also the economic components of the scaring process. The article analyzes the results of bird control management work at several waste management facilities. Based on these calculations, its possible to determine of costs level and select the optimal model for the work of specialists in bird scaring.

The problem of scaring birds, which has turned into a problem of protecting economic objects from biological damage caused by birds, was born in ancient times and remains relevant to this day. Elevators, fishing and animal husbandry facilities, and other agricultural structures have become the favorite habitats of synanthropic birds. The first ones cause irreparable economic damage to agriculture, destroying, in particular, crops in fields and gardens. One of the solutions to this problem, which became the goal of this work, is to increase the efficiency of protecting agricultural facilities from synanthropic birds with the help of electric bird repellents. To carry out this research work, an experimental stand was designed and constructed in the laboratory of the State Agrarian University of the Northern Trans-Urals, which received a positive decision for a patent. With its help, an analytical dependence of the magnitude of the scaring pulse on the mass of the bird was obtained; a method for calculating the minimum and maximum distances of the scaring range for the blue pigeon was developed.

Flocks of birds may cause major damage to fruit crops in the ripening phase. This problem is addressed by various methods for bird scaring; in many cases, however, the birds become accustomed to the distraction, and the applied scaring procedure loses its purpose. To help eliminate the difficulty, we present a system to detect flocks and to trigger an actuator that will scare the objects only when a flock passes through the monitored space. The actual detection is performed with artificial intelligence utilizing a convolutional neural network. Before teaching the network, we employed videocameras and a differential algorithm to detect all items moving in the vineyard. Such objects revealed in the images were labeled and then used in training, testing, and validating the network. The assessment of the detection algorithm required evaluating the parameters precision, recall, and F1 score. In terms of function, the algorithm is implemented in a module consisting of a microcomputer and a connected videocamera. When a flock is detected, the microcontroller will generate a signal to be wirelessly transmitted to the module, whose task is to trigger the scaring actuator.

In connection with the increase in the number of household facilities attractting birds and the widespread growth of synanthropic bird populations, the problem of ornithological safety is becoming more and more urgent. For effective scaring away of birds from territories where their presence is undesirable, it is necessary to understand what has brought these birds to this territory, its important to find out the reasons for the ornithological attractiveness of the economic object. This article describes a method by which its possible to calculate the ornithological attractiveness of any business object. These calculations allow to plan the place, time and mode of work of bird repellent specialists.

A brief history of the tradition of birds as motifs on textiles is followed by a catalogue of the birds in the Bayeux Tapestry and a discussion of their function. The possible significance of identifiable birds (cocks, doves, peacocks, storks), the birds of Aesop's fables and the creatures in the border ‘bird scaring scene’ is analysed. The individuality, in colouring and position, of all the border birds is demonstrated and the apparent interest which many of them take in the action of the main register is highlighted to suggest that the border birds present a commentary on, and audience-participation in, the narrative.

AbstractSeabird bycatch is widely regarded as the greatest threat globally to procellariiform seabirds. Although measures to reduce seabird–fishery interactions have been in existence for many years, uptake in fleets with high risk profiles remains variable. We recorded seabird bycatch and other interactions in the Namibian demersal longline fishery. Interaction rates were estimated for seasonal and spatial strata and scaled up to fishing effort data. Bycatch rates were 0.77 (95% CI 0.24–1.39) and 0.37 (95% CI 0.11–0.72) birds per 1,000 hooks in winter and summer, respectively. Scaling up to 2010, the most recent year for which complete data are available, suggests 20,567 (95% CI 6,328–37,935) birds were killed in this fishery that year. We compared bycatch rates to those from experimental fishing sets using mitigation measures (one or two bird-scaring lines and the replacement of standard concrete weights with 5 kg steel weights). All mitigation measures significantly reduced the bycatch rate. This study confirms the Namibian longline fishery has some of the highest known impacts on seabirds globally, but implementing simple measures could rapidly reduce those impacts. In November 2015 the Ministry of Fisheries and Marine Resources introduced regulations requiring the use of bird-scaring lines, line weighting and night setting in this fishery. A collaborative approach between NGOs, industry and government was important in achieving wide understanding and acceptance of the proposed mitigation measures in the lead up to the introduction of new fishery regulations.

The incidental mortality of seabirds in longline fisheries is a global issue. For reducing seabirds incidental capture, the implementation of deploying bird-scaring lines during the fishing operations is important. A set of bird scaring line was designed to provide the guideline of performance. Most of the components of the bird scaring line got from longline spare gears and the boat hardwares conveniently. The trials were conducted 33 trips in No.2 Yu-Shiun, off the coastal of southwest and east of Taiwan from 22 March to 3 November in 2005. A pair of birds scaring lines were towed in 3 different weights float respectively and the streamers suspend range has been measured from the stern of vessel at line setting. The average aerial coverage could reached 77.5~97.5 m over constantly under 7~10 kt vessel speed and 1.5~3.5 kg float was been towed. BTR were attached to the branchlines upper 2.2 m of hook. These data showed the depth of hooks may sink to 6.5 m by 7 kt setting . The results suggested that the streamers of recommend bird scaring line can suspend to 87.8 m astern of vessel provided a 3.5 kg float attached end of seaward under a variety of weather conditions and was fit in the minimum requirement standard. In the future, a fisherman-targeted education program might be developed and demonstrated how to make the bird scaring line and deploy. It is necessary to encourage the fishermen to deploy bird-scaring line and to promote the work of seabirds conservation.
