How to recognise it

The Pine Siskin is a small, streaky finch with a sharp, pointed bill.

Its brown-streaked body is accented by yellow edges on the wings and tail, most visible in flight. The bird has a short, notched tail and a somewhat flattened head profile.

Both sexes look similar, with males having slightly more yellow in their plumage. Juveniles resemble adults but may have less distinct markings and duller coloration overall.

Its song and calls

Pine Siskins are known for their high-pitched, buzzy calls, often described as a prolonged 'zreeee' or 'zree-e-e-e'.

Their song is a mix of warbles, twitters, and long buzzy notes, sometimes incorporating mimicry of other bird species. In flight, they make a distinctive 'tee-tee-tee' sound.

Tips for seeing it

  • Look for Pine Siskins in coniferous forests or mixed woodlands
  • Listen for their distinctive, buzzy 'zreeee' call
  • Check bird feeders, especially those offering nyjer or thistle seeds
  • Observe their rapid, undulating flight pattern

What it eats

Pine Siskins primarily feed on seeds, especially those from conifers, alders, and birches. They also consume buds, tree flowers, and occasionally insects.

Their specialized bill allows them to extract seeds from tightly closed pine cones, giving them an advantage in coniferous habitats.

Nesting and breeding

Pine Siskins typically breed from April to August, with timing varying based on location and food availability. Males court females with aerial displays and feeding rituals, often presenting food as part of the pair bonding process.

Nests are built high in coniferous trees, usually on a horizontal branch. The female constructs a cup-shaped nest using twigs, grass, and plant fibers, lined with soft materials like fur or feathers.

The female lays 3-4 pale blue-green eggs with brown spots. Incubation lasts about 13 days, with the female incubating while the male brings food. Nestlings fledge after 13-17 days but may depend on parents for several weeks.

Behaviour

Pine Siskins are highly social, often seen in large, noisy flocks. They exhibit acrobatic feeding behaviors, hanging upside down on conifer cones or seed heads to extract seeds.

During the breeding season, males perform elaborate courtship flights, making wide circles while singing continuously.

Conservation

While currently listed as Least Concern, Pine Siskins face threats from habitat loss due to deforestation and climate change. They are also susceptible to salmonellosis outbreaks at bird feeders, highlighting the importance of feeder hygiene and responsible bird feeding practices.
