The proposed study was carried out at Changa Manga that is an important woodland forest in Punjab. In this study, main emphasis was given on the population dynamics of birds in relation to the woodland characteristics particularly different types of forest habitats, different seasons (summer, winter), relationship between different species of birds, seasonal changes, species identification, census of birds and their population assessment. They connect all of us, from city dwellers to rural communities, to the environment. Birds are an excellent indicator of the overall health of an ecosystem. On this research identification of nature and severity of problems being faced by birds both resident and migratory was identified and concluded as recommendation for the welfare of our avifauna at the site.
In the site of study area resident birds are common and winter visitors, summer breeder birds were also recorded. In the study area 51 residents, 5 summer breeder, 21 winter visitor and 1 year round visitor species recorded. The total number of birds observed in Changa Manga Forest is 78 that show the most common birds in Changa Manga Forest are House Crow, Common Myna, Bank Myna, House Sparrow and Bee-eater etc.
The data collected from Changa Manga in May (524), June (384), July (544), August (418), September (425), October (487), November (647), December (593), January (532), February (604), March (630) and April (466).
The relative abundance is showed by house crow (7.8531). It is a garbage feeder so can easily be seen in areas which are the places of public interest, where people use to create or spread solid waste (wrapper, plastic bags, food material etc). Common Myna (4.4143), Bank Myna (4.3969), House sparrow (4.1641) and Blyth's Reed Warbler (3.1128), Small Sky-lark (2.3416), Common Babbler (2.6398), Blue-cheeked Bee-eater (2.0016), Small Sky Lark (2.3416), Long Tailed Grass Warbler (1.6631) and Indian Robin (1.6681) have abundance respectively. Census index (0.2422) and Shannon Wiener (5.5495) values were also calculated. The trophic levels were mention according to these; there were 263 birds' herbivores, 411 were omnivores, 391 were insectivores and 112 were carnivore's birds in the study area.
Hence there is a strong need to restore, conserve and preserve these existing woodland to maintain and improve the distribution, diversity and abundance of populations and habitats of breeding, migratory and nonbreeding birds throughout the land forests of the Pakistan
