A correlative study testing the impact of different urban congestions in Lahore upon the bird abundance and diversity was conducted in the monsoon and winter season. A platform of 6 feet diameter and 4 feet height, with a variety of seeds, was offered to attract the grainivorous birds. The number and variety of birds visiting the feeding station was noted, from Dawn to dusk after a period of 6 day installation, which depicted the bird's urbanization in the area. A significant increase in the abundance of birds was observed in the winter season. Areas with large sized pockets of vegetation supported the largest diversity of birds. Grain preference of the birds recorded in the different areas studied showed a relationship between the age long practices of feeding birds with the habituation of the birds.
In order of Preference Birds of most areas preferred Pearl Millet (Bajra) seeds, and Rice Seeds, over others. The next choice of food was shown to be Italian Millet and Red Italian Millet, when the amount of these decreased birds started feeding on, Sunflower, then Safflower, and Wheat. Mustard, corn and Chick peas remained feed of least preference. A weak correlation was found between urban population congestion and the number of pigeons, doves, babblers, house sparrows and silver bills. These birds are considered to be urbanized.
As shown in the Tables the results suggest that more grainivorous species and invasive species such as House Sparrows are present in the central parts of the city. The outskirts of Lahore, the sub urban areas enjoy a large diversity of avifauna. This finding is supported by Mathew and Naik (1993). Areas where a considerable amount of vegetation is present, such as parks, gardens or big lawns with a lot of vegetation provide a good habitat can be considered as "Pockets of Wilderness" These areas, provide food and habitat for a variety of bird species. Although an exponential increase in urban congestion of cities and a need for further development does not allow room for large areas supporting natural vegetation. However, a plan has to be developed which would ensure a set amount of area for vegetation, to support a healthy diversity of bird species.
