Tarin des pins
Spinus pinus
Oiseau
Petit fringille strié, marqué de jaune à l'aile et à la queue, au bec fin et pointu fait pour extraire la graine des cônes entrouverts et des chatons. C'est l'un des oiseaux les plus erratiques du continent : les tarins suivent la récolte de graines de conifères plutôt que le calendrier, si bien qu'un bois qui en abrite des centaines un hiver peut n'en abriter aucun le suivant.

Pin blanc de l'Est
De soutien / Plantes à graines
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.
Bouleau flexible
De soutien / Plantes à graines
Works the hanging catkins for seed with a fine pointed bill, often hanging upside down to reach them.
Sapin du Colorado
De soutien / Plantes à graines
Takes fir seed from the cones, in flocks whose size tracks the seed crop rather than the season.
Bouleau à papier
De soutien / Plantes à graines
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.
Épicéa d'Orient

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.
Coréopsis des teinturiers
De soutien / Plantes à graines
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.
Répartition
Niche dans les forêts de conifères de l'Alaska, du Canada, des montagnes de l'Ouest et du nord des États-Unis ainsi que des Appalaches. Hors saison de nidification, il est irruptif plutôt que migrateur au sens ordinaire : quand la récolte de graines du Nord échoue, les bandes descendent loin vers le sud et l'est du continent, et les bonnes années elles ne bougent presque pas.
