A system and method for monitoring the intensity and distribution of bird calls in the wild

Abstract

The invention provides a system for monitoring the intensity and distribution of birdsong in the wild, which includes a standing wave pickup microphone array, a control processing unit, a wireless data transmission unit, and a display and control unit connected sequentially; wherein, the standing wave pickup The sound microphone array and the control processing unit are connected by cables, and the control processing unit is installed in a waterproof housing; the standing wave pickup microphone array and the control processing unit are installed at the monitoring node in the field, and a number of birdsong signals in the field are collected and processed to obtain The best total bird song signal, through the wireless data transmission unit, sends the best total bird song signal to the display and control unit for display, realizing unattended automatic remote monitoring of bird song, and solving the problem of birds The rapid response to the monitoring of behavioral activities has broken through the technical bottleneck of remote automatic ecological monitoring of birds, and can be applied to the monitoring of birds and ecological environments in special environments such as islands and wetlands.

Description

technical field [0001] The invention relates to the technical field of ornithology, bird song monitoring and information, in particular to a system and method for monitoring the intensity and distribution of bird song in the wild. Background technique [0002] Islands are important habitats for birds, and they are also important places for the protection and utilization of the ecological environment of birds. Developed countries such as the United States and the United Kingdom have established national-scale bird monitoring networks and achieved good results. my country has also carried out a large number of bird surveys and monitoring work, mainly focusing on the research on the species, quantity and distribution of terrestrial birds in an area. In order to promote the monitoring of birds in my country, in 2011, the Nanjing Institute of Environmental Science of the Ministry of Environmental Protection organized a demonstration monitoring of biodiversity (birds), and explor...

AI Technical Summary

Problems solved by technology

At present, the traditional bird song monitoring method is mainly based on manpower, which is labor-intensive, has a small observation range, is greatly affected by the weather, and cannot record and analyze bird activities in real time.

In addition, field surveys and data analysis often require a lot of time, manpower, and material resources, resulting in high costs and low efficiency.

For island wetlands, there are still problems such as special geographical environment, inconvenient transportation, harsh and changeable climate, etc. As a result, traditional bird survey methods cannot achieve remote monitoring and are difficult to apply to the monitoring of island birds
