Passer domesticus: House Sparrow- The Race Rocks Taxonomy

 

Domain Eukarya
Kingdom Animalia
Phylum Chordata
Sub-Phylum Vertebrata
Class Aves
Order Passerifomes
Family Passeridae

Genus Passer
Species domesticus

Common Name: House Sparrow,  Passer domesticus

One of the worst introduced European species in North America because of their habit of preying on other nests in the area they are frequenting , 

Given that house sparrows are so common everywhere else, it is surprizing that they are rarely seen on Race Rocks. 

Normally this species can be quite damaging to other nesting birds but there are few other small birds that nest here other than the occasional barn swallow.

This bird was the subject of the Classic Paper by Bumpus on Limiting Factors
