Breeding Birds in Saidpur Cantonment Area, Bangladesh

Abstract/ Executive Summary:

Breeding status of birds in Bangladesh is more remarkable than that in other countries. Most of the resident birds breed here in the month of May, June and July. Because during these months all the insects lay eggs and finally these eggs are hatched into larva. So, in order to collect these larvae the birds lay eggs in their nests. Some birds like pigeon, dove, sparrow, babbler etc can lay eggs throughout the year. Maximum type of birds nest is twig or cup nest due to huge number of branch of the trees. There are some birds which build their nests with excellent or brilliant skill and some lay eggs in the tree holes. According to this research work minimum number of eggs’ laying is two and maximum is eight. Incubation period of the eggs depends on the egg size or the total components within the egg. Lowest hatching period is ten days with shrike and white eye and highest with cormorant and with adjutant, it is twenty nine days.

Commodity: Bird

Objectives:

Otherwise the research on birds breeding is limited. Maximum observations have been completed depending on specific birds. Breeding biology of birds like types of nests, number of eggs, hatching period, all these are so tough for observation. Besides research works depend on much more manpower, scientific instruments and so on. Already several steps have been taken for the conservation of birds through plantation programme. So, the numbers of birds have increased.

Methodology:

All the observations on birds like their breeding season, types of nests, number of eggs, egg colour and hatching period were completed skillfully. The breeding season on birds were observed by using video camera, placed it on the trees day by day. For the identification of the nest types and the height from the frond the nest materials were collected from the nest and appointed some manpower for this purpose. Some photographs were snapped with the high powerful zoom camera that helped for the identification of the nest types. Number of eggs and colours were identified with the help of climbing on the tree. Finally in order to observe the hatching period from the egg laying to the actual time the eggs were hatched have been considered. In case of nocturnal bird like nightjar, the torch light and video camera were used. From above all the observations were completed by high quality binoculars (8x50mm). Birds were identified by the using of some standard guide books on birds. The classification of birds was completed according to Salim Ali (Ali, 1941).

Achievement/Findings:

As our forest going to be extinct, but the present status of birds in Bangladesh are not bad. Moreover it can be said that most of these birds are breeding here successfully. But for having few numbers of high trees some birds like eagle, vulture, falcon, and accipiter cannot breed. Of the total birds of Bangladesh included all families most of the birds in the order Passeriformes. On the other hand the reproduction in the order Ciconiiformes is in second position. Old aged banyan and fig tree are the source for their breeding. Besides, Bangladesh is a temperate zone so all birds feels well here. At present, in Bangladesh, the IPM technique or biological control is applying for the protection of crops from insect so the use of insecticide is limited. Less use of insecticide is not harmful for nature. So, ultimately the number of birds is increasing. Awareness has increased in human beings for their existence or protection of nature. That is why they are taking some steps for their next generation to stay in this world.
