Pine Siskin
Spinus pinus
- tidak umum
- 40 km/h
- Risiko rendah
Tiny, streaky, and constantly arguing at the feeder. Wheezy little courier with a short fuse.
- Populasi
- ~46 million mature individuals globally, ~45 million in USA/Canada; population trend rated stable despite ~69% North American index decline 1966-2019
- Habitat
- Boreal and temperate coniferous/mixed forests (breeding and non-breeding), plantations, rural gardens, temperate shrubland, parks and suburban woodlands, especially where feeders are present; medium forest dependency
- Fakta menarik
- Pine Siskins normally run metabolic rates about 40% higher than a similarly sized songbird, and can push that rate up to five times normal during extreme cold, fueled by seeds stored in an expandable crop equal to about 10% of their body weight.
- Sebaran
- North America: breeds across Canada, the boreal forest, western mountains, and parts of the northern/western US; also occurs in Guatemala and Mexico; a full migrant that winters irregularly/irruptively across the rest of the US in response to conifer seed crops
- Makanan
- Seeds of conifers (pine, spruce, hemlock, larch, cedar) and weeds/deciduous trees; thistle/nyjer and hulled sunflower seeds at feeders; occasional suet, buds, insects, and tree sap from sapsucker wells
