Description

A kind of voice drive bird method

Technical field

The present invention relates to one and drive bird method, particularly relate to a kind of voice and drive bird method.

Background technology

At present, birds are mainly concentrated both ways the destruction of the mankind:

First aspect is that airport bird is hit, and refers to the flight safety accident that aircraft occurs with bird strikes in flight course.Due to factor impacts such as the minimizing of wild birds habitat, fragmentations, comparatively speaking airport and peripheral region more can meet their three large demands, that is: food, water, sheltered situation.But along with the fast development of economy, the acting in conjunction of the factors such as the increase of the flight frequency, type increase, makes airport bird hit accident and occurs more and more continually, one of three large disasters even having become World Airways transport service.

Second aspect is the fruit in infringement orchard, and in recent years due to the enhancing of China whole people environmental protection consciousness, and a shot at a bird shoot bird, catching bird behavior is restricted, and kind, the population quantity of bird are gone up to some extent; But the insect on field, trees is owing to effectively being controlled by agricultural chemicals, the food source of birds is reduced.Meanwhile, orchard area increases, and the fruit of various taste gets more and more, and make birds using melon and fruit as one of main food source, this has had a strong impact on the economic benefit in orchard.

Existing voice drive the many sound by playing huge noise or birds natural enemy of bird method and reach effect on driving birds, but the natural enemy of different birds is different, cause the cry of certain birds natural enemy sometimes can not reach the effect of driving bird, namely existing voice drive bird method and can not carry out targetedly driving bird, and for a long time single sound that birds can be made to produce behavior is tired, certain effect on driving birds can be reached when namely starting, but along with the growth of Applicative time, the reaction of birds is generally: bird is nervous, continue to play, bird peeps, continue to play, bird is ignored after peeping, therefore existing voice drive bird method can not Long-Time Service.

Summary of the invention

For the problems referred to above, the object of this invention is to provide one and birds can be avoided to produce behavior fatigue, thus the long-time voice that can reach fine effect on driving birds that use drive bird method.

For realizing above-mentioned technical purpose, the present invention takes following technical scheme: a kind of voice drive bird method, and it comprises the following steps: (1) is treated the region of driving bird and investigated, and respectively record four season bird region to be driven birds kind and quantity; (2) according to kind and the quantity of the birds of record in step (1), record the cry of more than one natural enemies of each birds respectively, and the cry of each natural enemy records some grades according to the size of sound decibel respectively; (3) form of shuffle is adopted for each birds in the region of bird to be driven, according to the ascending cry playing the natural enemy of more than one kind of this kind of birds step by step.

In described step (2), the sound of the natural enemy of each birds records five grades according to the size of decibel, comprises 30 decibels, 50 decibels, 70 decibels, 90 decibels and 110 decibels, and the sound recording time of each grade is 5 seconds.

When playing the natural enemy cry of often kind of birds in described step (3), play ascending for the sound of five grades step by step, the sound reproduction time of each grade is 5 seconds.

The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention is due to the cry by the different natural enemy of shuffle birds, make it possible to avoid birds to produce behavior tired, thus can use for a long time and can both reach good effect on driving birds.2, the present invention drives bird mode what drive that bird region adopts ascending broadcasting birds natural enemy cry, hightails after making birds produce constriction.3, the present invention records the multiple natural enemy of each birds targetedly respectively, and the cry playing this kind of birds natural enemy targetedly drives this birds, effectively improves and drives bird efficiency.The present invention designs uniqueness, simple to operate, can not damage birds, can be widely used in driving in bird of each place.

Embodiment
