"The has the distinction of being the smallest British bird; it is also one of the most widely distributed, being found throughout the United Kingdom. Furthermore, it is a resident throughout the year, is nowhere scarce, and in many places is very abundant. Yet it is well known only to those who are close observers of bird life. The gold crest is not a familiar figure, owing to its smallness and restlessness, which exceed that of all the other members of this restless family of birds, and make it difficult for the observer to see it well. Again, it is nearly always concealed from sight by the foliage, and in winter it keeps mostly among the evergreens, and at all times haunts by preference pine, fir, and yew trees. In the pale light of a winter day, more especially in cloudy weather, it is hard to see the greenish, restless little creature in his deep green bush or tree. Standing under, or close to, a wide-spreading old yew, half a dozen gold crests flitting incessantly about among the foliage in the gloomy interior of the trees look less like what they are than the small flitting shadows of birds."
