Crossbills travel in a small flock in search of seeds from the cones of pines, spruces, and firs. These characteristics can be used to split Red Crossbills into eight distinct types, and it is likely that the species will be divided into multiple species in the future.
The crossbill is a chunky finch with a large head and bill which is crossed over at the tips.
Because conifers produce seeds unpredictably, Red Crossbills sometimes wander (or “irrupt”) far beyond their usual range. This crossed bill is used to extract seeds from conifer cones. Their specialized bills allow them to break into unopened cones, giving them an advantage over other finch species.
Overall size, beak shape and call notes differ among types. East: This type has perhaps the most varied diet of the types and is the most widespread Red Crossbill call type in North America (Groth 1993), even occurring in areas of the Plains where ornamental conifers have been planted. The crossed bill tips are inserted between the scales of cones so that the tongue can lift the seed out. Use the “Foot Type Adaptation” pictures to determine the type of feet each bird has. Some foot types may be used more than once.

The crossbill is a genus, Loxia, of birds in the finch family (Fringillidae), with six species.These birds are characterised by the mandibles with crossed tips, which gives the group its English name.

Adult males tend to be red or orange in colour, and females green or yellow, but there is much variation.
Scottish Crossbill birds are specialist feeders on conifer cones and the unusual beak shape is an adaptation to assist the extraction of the seeds from the cone.
The Red crossbill is almost always found in mature seed-bearing forests in flocks ranging from a few to several hundred individuals. A distinctive finch with an unusual beak The red crossbill is a distinctive finch whose crooked beak usually catches one’s attention. Only one type of red crossbill can generally be found year-round in Nebraska in the Pine Ridge and Wildcat Hills. Crossbill, (genus Loxia), any of several species of birds of the finch family, Fringillidae (order Passeriformes), known for their crossed mandibles.
