Trepador canadiense
Sitta canadensis
Ave
Pequeño trepador de vientre rojizo propio de piceas, abetos, tsugas y pinos, y el de distribución más septentrional de su familia en América del Norte. Excava su propio agujero en madera muerta blanda y después unta resina pegajosa de conífera alrededor de la entrada, atravesando el hueco de un salto limpio para no tocar su propia defensa. En los años en que falla la cosecha de conos del norte abandona por completo la franja de coníferas y aparece muy al sur de su área habitual.

Tsuga del Canadá
De apoyo / Plantas con semillas
Takes the small hemlock seed and gleans insects from the bark and foliage, and nests in soft dead wood in the same stands.
Pino blanco del este
De apoyo / Plantas con semillas
Takes pine seed and wedges it into a bark crevice to hammer open, and excavates its nest hole in soft dead wood of the same stands.
Pícea de Noruega
De apoyo / Plantas con semillas
A spruce specialist that takes seed from the cones and insects from the bark, and nests in soft dead wood nearby.
Pícea oriental
De apoyo / Plantas con semillas
A spruce specialist in North America that takes seed from cones and insects from bark furrows, and a regular visitor to planted exotic conifers of the right structure. Marked plausible rather than documented because the association is with spruce as a genus in North American plantings, not a published feeding record on Picea orientalis, which is not a tree this bird evolved alongside.
Abeto de Fraser
De apoyo / Plantas de refugio
A conifer specialist of exactly this forest type. It excavates a nest hole in soft dead fir wood and seals the entrance with sticky resin, and takes fir seed and insects from the foliage year-round.

Plantas de follaje · 1
Works the trunks and branches of spruce-fir forest head-downwards for bark insects and takes conifer seed as well, and it excavates its nest cavity in soft decaying wood - which the wood-rotting fungi and broom rust on this species supply in quantity. A structurally weak, rot-prone conifer is a better cavity tree than a sound one.
Plantas de refugio · 4
A specialist of exactly this forest type. It excavates a nest hole in soft dead conifer wood and then smears the entrance with sticky conifer resin, which balsam fir supplies more freely than almost any other tree in its range, and it works the foliage for insects and seed year-round.
A conifer specialist of exactly this forest type. It excavates a nest hole in soft dead fir wood and seals the entrance with sticky resin, and takes fir seed and insects from the foliage year-round.
A conifer-forest specialist that gleans bark and foliage for insects, takes conifer seed in winter, and excavates its own nest hole in soft, decayed wood - which is exactly what grand fir supplies. This tree's structural weakness, thin bark and no pitch defence against rot, is what makes it valuable here: a living trunk with a rotten core is a cavity resource, and grand fir produces those more readily than most conifers.
This is the nuthatch of the spruce-fir belt and red spruce forest is core habitat across the whole range of the tree. It excavates its own hole in soft dead wood and smears conifer resin round the entrance, so a stand needs standing dead spruce as well as living trees to hold a breeding pair. Like the finches it abandons the conifer belt entirely in a failed cone year.
Distribución
Cría en bosques de coníferas de Canadá y Alaska y hacia el sur por las Montañas Rocosas, las cordilleras del Pacífico, los Grandes Lagos y los Apalaches hasta los bosques de picea y abeto de las montañas meridionales. Su área invernal es inestable por naturaleza: en los años de cosecha pobre las aves irrumpen muy al sur del bosque de cría.
