Programme offered: CBZ

OBJECTIVES:

1. 1. Arranging seminars & special lectures to enrich the students.
   2. Create awareness in students about life science which has direct dealing with their day to day life.
      The subject deals in depth about life process, control & coordination.
   3. To provide quality education in life science which helps them to understand nature better & develop harmonious relationship with it.
   4. To create awareness about ecological balance conservation of forest, & global warming.

Special Lecture Programme :

On 5/9/18, in our department we conduct special lecture programme for all CBZ students from I,II &III B.Sc, Prof. B. Siddaramaiah sir was invited as a resource person.

One Day Trip To Shukhavana :

The study  tour as per the curriculum was on exposure trip to a place of educational or historical important. On 22/02/2019, from our department we conduct one day trip to shuka vana  at Sri Ganapathi Sacchidananda Aashrama, Mysore for 1^st year CBZ students.

REPORT ON BIRD WATCHING

Bird Watching or birding is a form of wildlife observation of birds is a recreational activity and for the purpose of education. It can be done with the naked eye, through a visual enhancement device like binoculars and telescopes, by listening for birds sound, or by watching through camera.

Here in this report we are used to observe some local birds in our college campus and identify the birds with the use of details like plumage colour, beak, size and about habitat and finally we came to report the birds with their details. Purpose of the study is to know about the migration of birds and how they are actively involved in their life activities like food searching, nest building, reproduction and struggle for existence.

In our college campus, we are use to conduct an campus visit on 30/01/2020 at the time of 12pm to make an report on BIRD WATCHING  in and around the college campus. Our students are observed and identify some birds. The given following birds are identified in our campus they are,

1. COMMON PIGEON (Columbia livia)
2. COMMON MYNA (Acridothere tristis)
3. COMMON SPARROW (Passer domesticus)
4. COMMON CROW (Corvus splendens)
5. EAGLE (Haliacetus leucocephalus)
6. Common Pigeon: It has a dark bluish-grey head, neck, and chest with glossy yellowish, greenish, and reddish-purple iridescence along its neck and wing feathers. The iris is orange, red, or golden with a paler inner ring, and the bare skin round the eye is bluish-grey. The bill is grey-black with a conspicuous off-white care, and the feet are purplish-red. The nest is a flimsy platform of straw and sticks, laid on a ledge, under cover, often on the window ledges of buildings. They breeds at any time of the year, but peak times are spring and summer. Nesting sites are along coastal cliff faces, as well as the artificial cliff faces created by apartment buildings with accessible ledges or roof spaces.
7. Common Myna: The Common Myna is brown with a black head. It has a yellow bill, legs and bare eye skin. In flight it shows large white wing patches. The Common Myna is a member of the starling family and is also known as the Indian Myna or Indian Mynah. The Common Myna is closely associated with human habitation. In the evening, large groups of Common Mynas gather in communal roosts, mainly in the non-breeding season, in roof voids, bridges, and large trees, and numbers can reach up to several thousands. Common Mynas are accomplished scavengers, feeding on almost anything, including insects, fruits and vegetables, scraps, pets’ food and even fledgling sparrows. Common Mynas mate for life. During the breeding season there is usually considerable competition for nesting sites. Favored locations are in the walls and ceilings of buildings, making these birds a nuisance to humans. Nests are also placed in tree hollows, which are used by native birds. Nests are quite messy and consist of a variety of materials. Leaves, grasses, feathers and assorted items of rubbish are common materials.
8. Common Crow: The house crow also known as the Indian, grey necked crow. The forehead, crown, throat and upper breast are a richly glossed black, whilst the neck and breast are a lighter grey-brown in color. The wings, tail and legs are black. There are regional variations in the thickness of the bill and the depth of color in areas of the plumage. Due to a human population explosion in the areas it inhabits, this species has also proportionately multiplied. Being an omnivorous scavenger has enabled it to thrive in such circumstances. At least some trees in the local environment seem to be necessary for successful breeding although house crows occasionally nest on telephone towers. It lays 3–5 eggs in a typical stick nest, and occasionally there are several nests in the same tree.
9. Common Sparrow: It is a small bird that found in most parts of the world. Females and young birds are colored pale brown and grey, and males have brighter black, white, and brown markings. The house sparrow is closely associated with human habitation and cultivation. As an adult, the house sparrow mostly feeds on the seeds of grains and weeds, but it is opportunistic and adaptable, and eats whatever foods are available. In towns and cities, it often scavenges for food in garbage containers and congregates in the outdoors of restaurants. House sparrows can breed in the breeding season immediately following their hatching, and sometimes attempt to do so. Some birds breeding for the first time in tropical areas are only a few months old and still have juvenile plumage. Birds breeding for the first time are rarely successful in raising young, and reproductive success increases with age, as older birds breed earlier in the breeding season, and fledge more young.
10. Eagle: The bald eagle is a bird of prey. A sea eagle, it has two known subspecies,species pair with the white-tailed eagle (Haliaeetus albicilla). The plumage of an adult bald eagle is evenly dark brown with a white head and tail. The tail is moderately long and slightly wedge-shaped. Males and females are identical in plumage coloration, but sexual dimorphism is evident in the species, in that females are 25% larger than males.^[3] The beak, feet and irises are bright yellow. The legs are feather-free, and the toes are short and powerful with large talons. The bald eagle is usually quite sensitive to human activity while nesting, and is found most commonly in areas with minimal human disturbance. The bald eagle is an opportunistic carnivore with the capacity to consume a great variety of prey. Bald eagles are sexually mature at four or five years of age. When they are old enough to breed, they often return to the area where they were born. It is thought that bald eagles mate for life. However, if one member of a pair dies or disappears, the survivor will choose a new mate. A pair which has repeatedly failed in breeding attempts may split and look for new mates.
