Lawrence’s Goldfinch
Lawrence's Goldfinch
Spinus lawrencei
At a Glance
Uncommon and somewhat mysterious is this little finch of the far West. It nests very locally in the foothills of California and Baja, often near streams in fairly dry country. Its winter range varies: in some years, flocks spread well eastward across the southwestern deserts, but the reasons for these 'invasions' are not well understood. The twittering song of the male Lawrence's Goldfinch often includes brief imitations of the voices of other birds.

Behavior
Eggs
4-5, sometimes 3-6. Whitish to pale bluish-white, usually unmarked, sometimes with reddish spots. Incubation is by female only, probably about 12-13 days. Male feeds female during incubation.
Young
Both parents feed the nestlings. Young leave the nest about 11-13 days after hatching.
Feeding Behavior
Forages mostly in weeds, shrubs, and trees, often feeding quietly in a limited area, clambering about and occasionally hanging upside down to reach seeds. Sometimes feeds on the ground. Usually forages in flocks, even sometimes during nesting season.
Diet
Mostly seeds, some insects. Feeds mostly on the seeds of native weeds and other plants, such as fiddleneck, peppergrass, and chamise. Also eats plant galls, buds, and some insects. Will come to feed on salt.
Nesting
Does not seem to defend territory strongly; sometimes nests in loose colonies. In courtship, male follows female, perches near her and sings. Nest site is usually about 15-20' above the ground in a tree such as oak, cypress, sycamore, or pine, sometimes lower in shrubs or up to 40' above the ground. Nest is a small open cup made of grass, flower heads, plant down, feathers, animal hair. Female builds nest; male often accompanies her and may carry some material, but rarely provides any real help.
