| The high casualty rate among smaller birds can be partly attributed to the depredations of their natural predators, the sparrow hawk and kestrel. |
| Probably the most distinctive birdsong that I have ever heard belongs to the white-throated sparrow. |
| There you can find nesting the crissal thrasher and the black-chinned sparrow. |
| In the two first experiments, the experimental sparrow was placed in an aviary next to a cage containing either a rabbit or a cat. |
| He hid near nests of black woodpeckers, kingfishers, northern hazel hens and Eurasian sparrow hawks. |
| Songbirds also live here, including the snow bunting, raven, American tree sparrow, and hoary redpoll. |
