One day he heard the shutter of my camera click, and grew inquisitive. As soon as he had delivered his catch of larvæ, he hopped from stone to stone, until he finally stood upon one which allowed him to take a peep inside my hiding contrivance, one corner of which projected over the bank of the beck in such a way as to allow me to look down and see the water rushing past. Cocking his knowing little head first on one side and then the other, he looked up at me and made a most critical examination of everything he saw. He apparently came to the conclusion that I was quite harmless, for when he had satisfied his curiosity he sang a little song, and then flew away in search of more food for his mate and their chicks. [Illustration: landscape with waterfall] =THE CHIFFCHAFF.= [Illustration: flower and leaves] This tiny warbler measures only about four and three-quarter inches in length, is dull olive-green tinged with yellow above and yellowish-white below. Over the eye it wears a pale yellowish streak which grows whiter as it recedes. [Illustration: CHIFFCHAFF AND NEST.] The Chiffchaff is, with the exception of the hardy Wheatear, the first feathered wanderer to return to us in the spring, and is eagerly looked, or rather listened, for by naturalists because its welcome notes stand in their calendar as January 1 does to the rest of the world--the beginning of a New Year--not of days, weeks, and months, but of awakening life, activity, and joy. It arrives in March and departs again in October, some individuals having the hardihood to stay even through the winter in the mild south-western parts of England. [Illustration: NEST AND EGGS OF CHIFFCHAFF.] This species breeds generally throughout the southern and midland parts of England, but it is not common in the northern counties or in Scotland. It is met with in all suitable districts of Wales and Ireland, but is everywhere more or less local. Shady woods, well-timbered dells, and stream-sides with plenty of matured trees clustering round are beloved haunts of the Chiffchaff, which builds its nest on or near the ground amongst tall grass tangled with brambles and small bushes, hedge and ditch banks, and sometimes in ivy growing against trees and walls. The structure is oval, domed, and has an entrance hole in the side. It is made of dead grass, withered leaves, and moss--sometimes a few fern fronds are employed--and is lined with hair and feathers. The eggs, numbering from five to seven, are white, sparingly spotted with dark purplish-brown. It is by no means an easy matter for the inexperienced ornithologist to distinguish the Chiffchaff from the Willow Wren, although the species under notice is a trifle smaller and duller in colour.
