The Lista lighthouse area is invaded by two-barred crossbills again. The first ones showed up toward the end of July, and per August 3rd, we have estimated that there are a few tens of individuals in the plantation. It is nine years since the last invasion.

By M. Wold

From a distance one can occasionally see groups of several tens of two-barred crossbills appear above the trees in the planation, and a trip into the plantation with binoculars or a telescope will reveal several smart-looking individuals in the tree tops feasting on cone seeds.

Large populations further east combined with scarcity of food has probably made them migrate west this autumn. The two-barred crossbills breed and winter over in the East of Finland and Russia, and migrate occasionally to Sweden and Norway. Last time we were invaded by two-barred crossbills was in 2002. The first individuals started turning up during the second week of August, and by the end of the month over 100 individuals were estimated to reside in the plantation. Two-barred crossbills continued to be observed during the autumn and winter.

Yesterday, an extra mist net was put up in the plantation, and two individuals were caught and ringed, an adult male and a female.

The two-barred crossbills can be seen also elsewhere on Lista, particularly in plantation where there are conifers. The plumage is similar to the common crossbill, but can easily be recognized by the two broad white bars on the wings.

We expect that the two-barred crossbills will stay with us throughout the autumn and into the winter season.
