The number of guest birds at Jahangirnagar University is decreasing every year due to the influx of visitors

Hundreds of guest birds of various species fly to Jahangirnagar University (JU) every winter. Visitors gather to the campus to see the eye-catching naughtiness of the guest birds amidst the red water lily in the lakes.

However, this crowd is now becoming an infelicity for the guest birds. The number of guest birds is gradually decreasing in JU campus every year due to the harassment of visitors. Bird experts have also said that the destruction of the natural habitat is one of the reasons for the decline in the number of birds.

It has been learned that for the last three decades, guest birds have started coming to the JU campus at the beginning of winter. Guest birds began arriving on campus in late September. Since then the winter has increased, but the number of birds has not increased as expected due to the nuisance of visitors and lack of suitable habitat.

According to data from the university's zoology department, migratory birds usually start arriving in early September. As winter progresses, so does the number of birds. But this year the opposite has happened. In the beginning the birds came in groups but later they were rarely seen.

This year, the first migratory birds were spotted in the swimming pool area and at the Wildlife Rescue Center. After that, the birds flocked to the water body adjacent to the transport premises and the water body behind the new registrar's building, but at present the number of birds in these two lakes is low.

Bird experts say that these two lakes are on the side of the main road of the university, so the visitors gather more here. They come to see the birds and throw packets of chips and water bottles in the pond. As a result, the natural habitat of birds has been destroyed. Also, trying to get close to the birds and take pictures, the horns of motor vehicles on the road and the excessive noise disturb the birds. All in all, the birds are forced to leave the place.

Bird experts say the lack of water in the backyard of the university's new registrar's building and the failure to renovate the pool adjacent to the swimming pool have also contributed to the decline in bird numbers. It is also known that the visitors threw stones at the birds in the pond adjacent to the swimming pool.

Bird experts say there are no birds in the two lakes due to the crowds and noise of visitors. Apart from this, the water hyacinths adjacent to the swimming pool were not cleaned in time. Birds also need clear water in the pond. Birds do not feel comfortable in dirty water. That is why the birds are leaving the campus as well as moving to other ponds.

In this context, Professor Kamrul Hasan of the Department of Zoology said, 'The number of birds are comparatively less this time. Last year, more than 7,000 endangered birds of 12 species came to the campus. Which is the highest in the last three decades. The guest birds came more last year as the nuisance was less due to COVID virus. But this year, about four thousand birds of two species have come to the campus. However, the bird expert hopes that the number of birds will increase in the future.

The first guest bird came to JU in 1986. So far, 195 species of birds have been spotted on campus. Of these, 69 species of migratory birds. The rest are all native.
