A high-altitude pioneer tree, its young needles are fine enough to allow light to filter through. It is the only conifer to drop its needles in winter. Another distinctive feature: in the spring, its cones are a characteristic dark purple. The larch is one of the few European tree species that is imputrescible, that is to say, it does not rot.

It is a small passerine in the tit family Paridae. It has brown plumage on its back, lighter on the underside. What makes it easy to identify is the triangular crest adorning its head.

Outside the breeding season, crested tits, in the company of other tits, wrens and various other passerines, congregate into boisterous flocks which the French call rondes (patrols).
