Coniferous forests.
Behaviour
The diet includes insects such as moths, beetles, ants, wasps, butterflies, caterpillars, spiders and elderberries and weed seeds. They also drink tree sap and some fruit.
Both sexes build the nest which is a hanging globe shaped cup among twigs of a pine branch. The nest is built of moss and cobwebs and lined with feathers, rootlets and soft bark. The nest can be found in a spruce, firs or pines. 5-11 (usually 7-9) eggs are laid which are white with brown spots. The eggs hatch within 12-13 days and are incubated by the female. The first young leaves the nest approximately 13 days after hatching.
