The merlin is a falcon that is found in the Northern Hemisphere. They breed in the northern portions of their territory, Canada, Alaska, Siberia, the Netherlands and such. They winter in the southern US, Mexico, Central America, Northern South America, the Baltic Countries, Northern Africa, the Middle East, and China. Here in southern Minnesota we have a few nesting pairs that are found in the Twin Cities. Merlin's do not build their own nest but take over the nest of another raptor or more typically a crow. They are much more prevalent in the northern part of the state like up in Duluth.
