• Birds play important roles in many ecosystems.
  
• Birds are relatively easy to identify.
  
• The disappearance and/or appearance of certain species may reflect major habitat changes.
  
• Some birds are considered pests, others beneficial and each may be attracted to different habitats.

What birds should we study?

Bird researchers have found over 50 bird species in the Phoenix metropolitan area. The most numerous of these bird species are the: House Finch, Starling, House Sparrow, Mourning Dove, Inca Dove, Pigeon (Rock Dove) and Great-tailed Grackle. (see identification key)

After you become familiar with these 7 bird species and any other birds that are common in your area, you can begin making scientific observations.

What do they tell us about our urban ecosystem?

Data from the bird surveys, as well as experiments you design, will help CAP LTER scientists identify which urban areas attracts what types of birds. This information may help people living in Phoenix design landscapes that attract a wider variety of bird species. CAP LTER scientists will be able to analyze how city zoning ordinances and regulations might influence bird abundance and diversity.

CAP LTER scientists will also be able to create a data base of the number and kinds birds in the Phoenix area. They can use this data to document changes over time and space and to investigate why these changes occur.
