Nests of this species were found in 1821 by Johana Wilhelm Zetterstedt near Juckasj,rwi in Swedish Lapland, but little was known concerning its nidification until 1855, when John Wolley, after two years' ineffectual search, succeeded in obtaining near the Finnish village Muonioniska, on the Swedish frontier, well-authenticated specimens with the eggs, both of which are like exaggerated bullfinches'.
In the Spanish plains, however, the young are often produced in nests built in trees, or among tall bamboos in FIG.
The true love-birds (Agapornis) may also be said to build nests, for they line their nest-hole with strips of pliant bark.
The nests of different kinds of ants are constructed in very different situations; many species (Lasius, for example) make underground nests; galleries and chambers being hollowed out in the soil, and opening by small holes on the surface, or protected above by a large stone.
In tropical countries ants sometimes make their nests in the hollow thorns of trees or on leaves; species with this habit are believed to make a return to the tree for the shelter that it affords by protecting it from the ravages of other insects, including their own leaf-cutting relations.
