Their nests are hidden well, on a horizontal branch some distance from a conifer’s trunk. Insects supplement their diet in summer. According to All About Birds resource, the total breeding population size of the Pine siskin is around 40 million individuals. Pine siskins are migratory finches, known for their conspicuous streaks and slender bills which separate them from American sparrows and other similar sized finches. They form flocks at all times of the year, winter flocks being sometimes quite large. Small seeds, especially thistle, red alder, birch, and spruce seeds, make up the majority of the Pine Siskin's diet. In the wild, pine, spruce, alder, birch, grass, sunflower and weed seeds are their go-to foods. They are active foragers, climbing around nimbly amongst forest canopies and hedgerows, frequently hanging upside-down. Pine siskins are mainly active during the daytime, although some may seek food by moonlight when it is scarce. The young leave the nest after 13 to 17 days, and the parents continue to feed the young for about three more weeks. Predators: ... Tree seeds are the main food source for siskins, with those of alder, birch, spruce and pine all commonly taken. Siskins eat the seed of spruce, pine and birch but their favourite is alder and because alder trees are most common on damp ground this is where siskins are most likely to be spotted, often in quite large flocks. During the winter period and migration, they can be seen in many different semi-open areas, such as forest edges and fields of weeds. In summer they will also eat insects, especially aphids, feeding them to their chicks. View full list of Washington State's Species of Special Concern. Currently this species is classified as Least Concern (LC) on the IUCN Red List and its numbers today remain stable. The siskin population is doing well, with a 61% increase recorded between 1995 and 2015. The short, stubby nature of the siskin bill makes it convenient to eat these types of cone seeds. The male often helps her building the nest by gathering potential materials. Maintaining large tracts of coniferous forest will help keep this bird common.

Many finches have undulating flight patterns, and may give calls while in flight. Pine siskins provide an important function by eating many species of destructive insect and weed pests. Loss of habitat due to forest-clearing may be mitigated by new coniferous forests planted commercially, and by the pine siskin’s adaptability at nesting in ornamental trees and shrubs. Oscines are capable of more complex song, and are considered the true songbirds.
