Artificial Cover in Hiding.--When studying the larger or the shyer species it is sometimes well to hide one's self from view with whatever articles are at hand that resemble the natural surroundings. This may be done by covering with hay if in a field, or by holding some leafy branches about you if in the woods.
On a lonely island in Pamlico Sound I once got some fishermen to cover me with sand and sea-shells, and in that way managed to get a close view of {17} the large flocks of Cormorants that came there to roost every night. The island was small and perfectly barren, and any other method of attempted concealment would have failed utterly.
Another time, while crouched among some boulders watching for a flock of Gambel's Quails to come to a water-hole in the Santa Catalina Mountains of Arizona, a Canyon Wren alighted on my back, for I was covered with an old tent fly so spotted with mildew that it closely resembled the neighbouring rocks. A moment later it flew to a point scarcely more than a foot from my face, when, after one terrified look, it departed.

The Umbrella Blind.--A device now often used by ornithologists is the umbrella blind, which is easy to construct. Take a stout umbrella, remove the handle, and insert the end in a hollow brass rod five feet long. Sharpen the rod at the other end and thrust it into the ground. Over the raised umbrella throw a dark green cloth cut and sewed so as to make a curtain that will reach the ground all round. A {19} draw-string will make it fit over the top. Get inside, cut a few vertical observation slits six inches long, and your work is done. Erect this within ten feet of a nest, and leave it alone for a few hours. The birds will quickly get accustomed to it so that later you may go inside and watch at close range without disturbing them in the least. This blind is often used for close bird photography. I have taken pictures of Herring Gulls at a distance of only six feet with the aid of such a blind. If you wish to use it on a windy day it may be stayed by a few guy-lines from the top and sides.

The foregoing instructions include all the necessary aids to a beginner in bird study who desires to start afield properly equipped. To summarize them, all that is really necessary is a field glass, a notebook for memoranda, inconspicuous clothing, and a desire to listen and learn.
In the next chapter we shall discuss some of the things to be learned in the study of the life about the nest.

CHAPTER II
THE LIFE ABOUT THE NEST
In view of the fact that birds display much activity about their nests there is a great advantage in studying the nesting bird. Once locate an occupied nest, and by quietly watching for a time, your field glass and bird guide will usually enable you to learn the owner's name. If you do not know where any nest is to be found go out and hunt for one. This in itself will be an exciting sport, although it should be pursued with good judgment. Children unattended should not be permitted to hunt nests in spring. A very excellent way to find one is to keep a sharp watch upon birds at the time when they are engaged in nest building.
Nest Hunting.--By noticing every bird suspected of being interested in domestic affairs, you are pretty {22} sure to see one before long with grass, twigs, rootlets, or something of the kind in its bill. Now watch closely, for you are in a fair way to discover a nest. The bird may not go directly to the spot. If it suspects it is being watched it may hop from twig to twig and from bush to bush for many minutes before revealing its secret, and if it becomes very apprehensive it may even
