About These Birds
Hawfinch
The hawfinch possesses the most powerful bill relative to body size of any European bird, capable of cracking cherry stones that require a force of 27-43 kg. Despite its distinctive appearance, it is famously shy and difficult to observe. The skull contains special adaptations to absorb the enormous forces generated during seed-cracking.
Black-capped Siskin
The Black-capped Siskin is a small finch restricted to the high-altitude pine and mixed forests of southern Mexico and Guatemala, with males showing a bold black cap contrasting with yellow-green plumage and white wingbars. It inhabits open highland forests and forest edges above 2,000 meters. It feeds primarily on small seeds from conifers, grasses, and other plants.
