Petirrojo americano
Turdus migratorius
Ave
Zorzal abundante y ampliamente distribuido que divide su dieta estacionalmente: lombrices de tierra, insectos y otros invertebrados dominan en primavera y verano, mientras que las frutas blandas se convierten en el alimento principal a finales del verano, el otoño y el invierno. Los petirrojos consumen una amplia variedad de frutos nativos, incluidos cerezos silvestres, espinos, cornejos, amelanchiers y moreras, y dispersan semillas por el paisaje al moverse en bandadas invernales. La especie anida en una copa abierta, típicamente sobre una rama horizontal de árbol o arbusto, por lo que los árboles y arbustos frutales sirven tanto de alimento como de estructura de nidificación en un jardín.
Conservación
Lista Roja de la IUCN: Preocupación Menor. Se encuentra entre las aves terrestres más numerosas y ampliamente distribuidas de América del Norte, con una población continental estable o en aumento; sin estado especial de conservación.

NC State Extension names the American robin among the songbirds that eat beautyberry fruit through fall and early winter.
Robins and other fruit-eating birds strip the small persistent pomes in winter - and in doing so disperse the fertile seed far from the parent tree, which is the main way Callery pear invades new ground. This is real wildlife use, but it works against native habitat.
Robins overwintering in the north depend on persistent fleshy fruit rather than on invertebrates, and juniper cones are a staple of that diet. A pollinated female holding two seasons of cones at once is a longer-lasting resource than most single-crop shrubs.
Robins that overwinter north switch off earthworms entirely and onto fruit, and juniper cones are among the most reliable winter items available to them. Birds pass the seeds intact, which is the species' main dispersal route into old fields and pasture edges.
Robins take juniper cones heavily in late winter, when the persistent blue cones are among the few fleshy foods still on the plant. The two-year ripening cycle means a fruiting female carries both green and ripe cones at once, which spreads the resource across seasons.
Robins are among the heaviest consumers of small autumn drupes in eastern North America and gray dogwood fruit is the right size, timing and lipid content for them. Marked plausible rather than documented only because the Wildflower Center names bluebird, cardinal and downy woodpecker specifically and does not extend its list; the general fruit-eating record for the species is strong enough that this is a cautious label rather than a doubtful claim.
Robins and other fruit-eating songbirds eat the persistent red berries and disperse the seed - the documented mechanism by which Japanese barberry escapes into and invades natural areas. Bird use here drives the invasion rather than indicating habitat value.
Birds including robins and thrushes consume the ripening drupes in autumn; NC State Extension documents bird use of Viburnum carlesii fruit.
Robins forage heavily on the woodland floor and take large quantities of small autumn drupes, and a knee-high fruiting shrub puts the crop exactly where they already are. Plausible on the same footing as the waxwing: the general fruit-eating record for the species is firm, but no cited source names the bird.
Robins are among the heaviest consumers of small drupes in eastern North America and take persistent winter fruit readily. Listed on the same footing as the waxwing: the general fruit-eating record for the species is strong, but the cited source stops at a category rather than a species list.
Robins are among the thrushes that take dogwood fruit heavily, and they are usually the birds that empty a garden specimen. Wikipedia records at least eleven bird species feeding on the fruit of this species; the robin is the one a gardener will actually notice, because it feeds in the open and returns repeatedly to the same plant.
Distribución
Se reproduce en casi toda América del Norte, desde Alaska y Canadá hacia el sur a través de los Estados Unidos hasta México; las poblaciones del norte migran al sur en invierno mientras que muchas poblaciones son residentes durante todo el año.
