Goldcrests and aphids

Glókollur – Goldcrest – Regulus regulus

After a warm summer Goldcrests have prospered in Icelandic forests. They mostly keep to spruce trees but can also be spotted in  larch trees, birch and contorta pine groves.

Green Spruce Aphid (Elatobium abietinum) on Sitka Spruce  needle (Picea sitchensis).

The winter should also be a good one for these little birds that once were vagrants. Their main food source in South Iceland are minute bugs called aphids that suck sap from spruce trees. These aphids are now  reproducing rapidly  on the Sitka spruce (Picea sitchensis).


We spotted at least four Goldcrests last week in Hellisskógur by Selfoss.
