Europe's smallest bird, weighing less than a coin. Crosses the North Sea on those wings every autumn.
- Populasi
- Roughly 80-200 million mature individuals globally, with a declining trend in parts of Europe though overall considered stable/not threatened
- Habitat
- Mature coniferous and mixed woodland, especially spruce, larch, Scots pine, silver fir and mountain pine; also gardens, parks, and deciduous woodland/shrub outside the breeding season; from lowlands up to ~4,800 m elevation
- Fakta menarik
- One of Europe's smallest birds at 4.5-7 grams, the goldcrest has an annual adult mortality over 80% (typical life expectancy around 8 months), yet survives freezing winter nights by huddling in tight collective roosts in dense foliage, and the oldest ringed individual lived nearly 5 years.
- Sebaran
