# Bird Perching Behavior

Medium
Ever wondered how the size of a bird affects its perching behavior? In this experiment, you'll measure the distance between crows and sparrows when they perch on a wire. Then, you'll compare the results to see if the size of the bird affects its perching behavior.

## Hypothesis

The hypothesis is that the crow, being a larger bird, will put a greater distance between itself and another crow when perching on a wire. The sparrow, being a smaller bird, will put a smaller distance between itself and another sparrow when perching on a wire.

## Method & Materials

You will look for overhead power cables or telephone cables that crows and sparrows often perch on. You will mount a ruler horizontally, some distance from the cable poles. You will measure the distance between the birds when they sit on the cable.
You will need a long ruler (transparent), a roll of duct tape, a measuring tape, an overhead power cable line or telephone line on which birds can perch, a calculator, and 2 sticks.

## Results

The results of the experiment showed that the hypothesis holds true: the crow puts a greater distance between itself and another crow when it perches on a wire. The sparrow puts a smaller distance between itself and another sparrow when perching on a wire.

## Why do this project?

This science project is interesting because it shows how the size of a bird affects its perching behavior. It also shows how birds have a way of measuring the distance between their perching neighbor.

## Also Consider

Consider conducting the experiment under different weather conditions (a sunny, cloudy, windy or rainy days). Also, identify a different species of bird for the experiment (eg. pigeons). How does their behavior compare with that of the birds in this experiment?
