Finches
These small, often colourful birds have a strong usually conical beak used for cracking the seeds, upon which they feed.
The Pine Siskin has a streaked breast, rather like that of the house finch, but it has touches of yellow on the wings. It is found around here throughout the year, but is most common in the winter and spring when its raspy call, zztweeeez is a staple of the season.

The American Goldfinch is almost always seen in flocks feeding on the seeds of trees or smaller plants. In the winter (shown here), both sexes look nearly alike: a dull yellow-olive, darker above with dark wings bearing white bars. In the summer the male becomes has a bright yellow body and a black forehead.

The Pine Siskin has an undulating flight pattern: between rapid wing beats it coasts with folded wings. Yet, when one sees the siskin in a steep climb yet with folded wings, as here, it does look odd.
