Jilguero pinero
Spinus pinus
Ave
Pequeño fringílido estriado con destellos amarillos en el ala y la cola y un pico fino y afilado, hecho para extraer la semilla de conos entreabiertos y de amentos. Es una de las aves más erráticas del continente: los jilgueros pineros siguen la cosecha de semilla de las coníferas y no el calendario, de modo que un bosque que alberga cientos un invierno puede no albergar ninguno al siguiente.

Pino blanco del este
De apoyo / Plantas con semillas
Works the cones for seed with a fine pointed bill, often hanging upside down to reach it. Flock size swings hugely between years with the size of the seed crop.
Abedul dulce
De apoyo / Plantas con semillas
Works the hanging catkins for seed with a fine pointed bill, often hanging upside down to reach them.
Abeto del Colorado
De apoyo / Plantas con semillas
Takes fir seed from the cones, in flocks whose size tracks the seed crop rather than the season.
Abedul de papel
De apoyo / Plantas con semillas
Birch catkin seed is one of its staples away from the conifers, and a heavy catkin crop is one of the things that decides where a wandering flock spends the winter.
Pícea oriental
De apoyo / Plantas con semillas
Siskins are small-billed conifer-seed finches that move in irruptive flocks and work shed and shedding seed on spruce, and a mature coning Oriental spruce in a North American garden is a plausible stop on that circuit. Plausible rather than documented for the same reason as the nuthatch: the tie is to spruce seed generally, not to this species specifically.
Coreopsis de las llanuras
De apoyo / Plantas con semillas
Listed on the same footing as the goldfinch and for the same reason - siskins are small finches that feed heavily on composite seed in autumn and winter flocks, and standing coreopsis stems hold their achenes above snow. Cutting a meadow to the ground in September removes this entirely, which is the practical point of recording it.

A small nomadic conifer-seed finch of the boreal and montane forest, and one that moves in irruptive flocks in response to the size of the regional conifer seed crop rather than to weather. Fir seed is among the small winged conifer seeds it works, taken from the cones and from the ground beneath as the cones shatter.
A regular forager on Douglas fir seed, working the cones with a fine bill and arriving in numbers that swing with the size of the crop.
Works the cones for seed with a fine pointed bill, often hanging upside down to reach it. Flock size swings hugely between years with the size of the seed crop.
Works conifer seed in flocks whose numbers track the crop rather than the season, and takes fir seed both from the crown and from the ground once the cones have broken up and scattered it. A heavy cone year in a grand fir stand can pull siskins in from a long way off.

Siskins work the same crop with a much finer bill, prising seed out of cones that have begun to open rather than forcing closed ones. Their irruptive movements track northeastern conifer seed the way crossbill movements do, so the two turn up together in a good red spruce year. Old cones persist on the tree and open in dry weather, which extends the resource well past autumn.
Takes fir seed in flocks in the same high-elevation spruce-fir forests, and like the crossbill it is an irruptive rather than a resident presence - a poor cone year in the mountains sends siskins far downslope and far south of where they nested.
Works the hanging catkins for seed with a fine pointed bill, often hanging upside down to reach them.
Takes fir seed from the cones, in flocks whose size tracks the seed crop rather than the season.
Distribución
Cría en bosques de coníferas de Alaska, Canadá, las montañas del oeste y el norte y los Apalaches de Estados Unidos. Fuera de la época de cría es irruptivo más que migrador en el sentido habitual: cuando falla la cosecha de semilla del norte, los bandos se desplazan muy al sur y al este del continente, y en los años buenos apenas se mueven.
