A conservation biologist is investigating whether there is a significant difference in the primary nesting site preferences between two closely related migratory bird species: the Pied Flycatcher and the Spotted Flycatcher. The biologist records the primary nesting site choice for 180 birds during the spring nesting season.
Table displaying the nesting site frequencies for each species across different habitats
| Deciduous woodland | Coniferous forest | Urban gardens | Scrubland | |
|---|---|---|---|---|
| Pied Flycatcher | 45 | 12 | 8 | 15 |
| Spotted Flycatcher | 20 | 25 | 22 | 33 |
