Pintassilgo-americano
Spinus tristis
Ave
Pequeno pássaro canoro granívoro que se alimenta intensamente de sementes de flores compostas no fim do verão e no outono — especialmente sementes de Echinacea, Rudbeckia, girassol e áster. O pintassilgo é a razão canônica pela qual a recomendação permanente da NC State Extension para essas plantas é 'deixar as cabeças de sementes em pé durante o inverno'.

One of the canonical late-summer goldfinch food sources; goldfinch breeding timing in much of North America is synchronized with sunflower seed maturation.
Goldfinches and other small seed-eating birds will pick seed from spent marigold heads in late season; leaving some heads to ripen supports this foraging.
American goldfinches eat the soft, early-spring elm samaras when little other seed is available; the tie is real but opportunistic, so it is graded plausible rather than documented.
Composite seed heads feed goldfinches and other small seed-eating songbirds through fall and winter when seeds are allowed to dry on the plant.
The abundant small seed on the ripe spikes is taken by seed-eating finches; goldfinches readily forage low weedy seed heads, inferred from the genus's known value as bird seed rather than species-cited.
Goldfinches and other small seed-eating birds can pick over the ripening seed heads in fall if stems are left standing.
Goldfinches pick seed from the rounded ripening heads in late summer and fall — a reason to leave spent blooms standing at season's end.
Small seed-eating birds will pick over ripening or spilled oat grain where heads are left standing, a common draw of small-grain plantings.
Cosmos left to set seed is a noted food source for seed-eating songbirds; NC State Extension lists the plant as attracting birds.
Seed-eating finches will take the small seeds from dandelion heads, one of many wild composite seeds in their diet.
NC State: "Goldfinches eat the seeds with relish." Leave the standing seedheads through winter for goldfinch + other songbird forage.
Small-seeded finches feed on hemlock seed from the drooping cones in fall and winter; goldfinches and their relatives (siskins, crossbills) are typical visitors to seeding conifers, so the association is plausible as a generic finch-seed tie.
Small finches pick seed from the ripened standing heads in fall — a reason to leave the final flush uncut.
Goldfinches and other small finches eat the seeds from spent blanketflower heads in late summer and fall; leaving seedheads standing supports this foraging.
Small-seeded finches feed on spruce seed shed from the large pendulous cones in fall and winter; goldfinches and their relatives (siskins, crossbills) are typical visitors to seeding conifers, so the seed-foraging tie is plausible as a generic finch-on-conifer association.
Goldfinches feed heavily on Echinacea seed heads in late summer and fall — the canonical reason to leave seed heads standing.
Missouri Botanical Garden PlantFinder notes local songbird populations — particularly finches — love to feed on the seeds, and recommends saving seed heads to feed birds in winter.
