Urbanization on it’s development would also vary, as urban

Urbanization refers to the process of modifying a rural area into more urban and such that is executed by implementing more constructive projects in a specific area. It impacts the surrounding of the area through physical changes as well as through changes made to the nativeness of the place (McKinney 2006). It acts as a medium that impacts various factors of an environment, such as, natural patterns, animal movement, population characteristics and wildlife habitat (McKinney 2002, Hansen et al. 2005, Crooks et al. 2010, Riley et al. 2010). Important to this study, as urbanization widespread, it would decrease the types of species found in an area due to a major change in the natural setting, thus demonstrating impacts on biodiversity (Marzluff 2001, Chace and Walsh 2006). 
Although, the loss of biodiversity is related with many factors, the most important one relevant to this study is human population density and it’s correlation with urbanization. The relationship between human population density and biodiversity exists in the sense that if an area is more developed, thus has a high population density, it would have a low biodiversity due to lack of resources (habitat, movement, etc) available for species living and it would also relate to high competition present in that area. The type of species found in different areas depending on it’s development would also vary, as urban areas tend to have less native birds and more native birds would only be found in less urban areas; outwards from the core of the urban area (Godefroid, S). 
The main focus of this study was to observe that how does urbanization in the environments of downtown Calgary, public parks and rural forests affect biodiversity. The proposed hypothesis was that low human population density affects bird biodiversity due to the lack of human developed space. Human developed space is referring to the extent of urbanization of an area. If there is low human population density in an area, the area would be subjected to have high bird biodiversity because it had experienced less change of the natural setting of it’s environment. On the contrast, if an area had experienced major changes to it’s natural ecological patterns, then it would be subjected to have low bird biodiversity due to factors like loss of habitat. First prediction that is made if the hypothesis is true, is that, there will be a higher biodiversity of birds in areas of lower population density because those areas exhibit minimum to no change in the environment. Second one is that, in areas of low population density, there will more native birds because when an area has experienced minimum to no development, the habitat was preserved for birds that allowed them to stay instead of fleeing away for more resources. The third prediction made is that, there will be a bigger difference between some of the areas than other, as in there will be a bigger decrease in diversity between a park and downtown than there will be between a park and a residential areas because of the extent of urbanization that the areas have experienced.
