Pine Siskin, Spinus pinus |
|
![]() Pine Siskins look like House or Purple Finches, but are more closely related to the goldfinches, their cousins in the genus Spinus, a kinship seen in the yellow linings of their flight feathers. They nest in the mountains, and some years winter at higher altitudes as well, as with the bird above, photographed in November in the Santa Cruz Mountain foothills. Other winters, depending on food sources, they winter further down in the lowlands, including at our feeders in Silicon Valley, see bottom. |

![]() The bird above was nesting in the Chiricahua Mountains of southeastern Arizona. Below, another Arizona mountain nester, photographed in Madera Canyon. |
