Kinglet (regulus cristatus, Ray), a well known European bird, often called golden-crowned warbler and wren. It is 3 1/2 in. long, yellowish olive-green above and yellowish gray below, with an orange-yellow crest bordered on each side with black. Though a permanent resident in Great Britain, considerable numbers come from the north in winter; they are fond of fir woods, very sociable with the titmice and creepers, hopping actively from branch to branch and clinging in various positions to the twigs in search of small insects. The nest is neat and cup-shaped, made of moss and lined with feathers, so suspended from three or four twigs that the branch shelters the opening; the eggs are six to ten; the female is very bold when hatching, and both sexes are very attentive to the young; the song is soft and pleasing. There are two nearly allied species of this genus in North America: the ruby-crowned and golden-crested kinglet or wren, the R. calendula and satrapa of Lichtenstein, the former with a concealed crimson and the latter with an orange-red crown.
