Description | ||
This experiment was conducted to investigate the relationship between the size of a bird and its perching behavior. Specifically, does the size of a bird affect the distance that it puts between itself and another bird, when both are perching on a wire? Crows and house sparrows were used as subjects for this experiment. | ||

1. For this experiment, the independent variable is the species of the birds that perch on a selected overhead power cable line (look for crows and sparrows in particular). The dependent variable is length of the distance between the birds when they sit on the cable. Position a ruler at a particular distance from the poles and calculate the length of the distance between the birds using ratios. The constants (control variables) are the distance between the ruler and the cable, the distance between the poles and the types of birds observed. 2. Look for overhead power cables or ..... |
