APPENDIX. 



Our object in adding this Appendix is simply a wish to make the boo\ 

 more complete by adding notices, more or less detailed, of the nests and 

 eggs and any interesting breeding-season peculiarities of birds recognized 

 as really well entitled to the name of British Birds, but not happening to 

 remain within the limits of Britain to breed. The first bird of the kind is 

 that which, in our complete list, is numbered 



7. GREENLAND FALCON. 



The equivalent to Mr. Yarrell's Gyr Falcon. 



8. ICELAND FALCON. 



These two species are now, I believe, looked upon as established, but the 

 differences between them are not excessively striking, except it be to a scien- 

 tific naturalist. Mr. Hewitson has figured an egg of the Iceland Falcon, 

 which he believes may have lost some of its colour. It was taken from a nest 

 made with sticks and roots, lined with wool, which once perhaps was the 

 nest of a Raven. The nest in question was in a cliff, and had the remains of 

 many sorts of birds Whimbrels, Golden Plovers, Guillemots, Ducks strewed 

 round it. The egg is of a buffy red colour, mottled and speckled very thickly 

 in places with deeper red. 



30. SNOWY OWL. 



Sufficiently often met with in North Britain (and even occurring sometime! 

 in England) to merit a short notice here. It inhabits Sweden, Norway, Lap- 

 land and the greater part of Northern Europe. These birds are accustomed 

 to take their prey by daylight, and seem, from the accounts received, to be 

 in the habit of " bolting " their food, when not very large, whole. It makes 

 its nest on the ground, and lays in it three or four white eggs. 



34. GREAT GREY SHRIKE. 



This bird is met with in Denmark and other northern countries of Western 

 Europe, and also in Russia, Germany and France, It is said to frequent 

 woods and forests, and to build upon trees at some distance from the 

 ground, as well as in thick bushes and hedges. The nest is made of roots, 

 moss, wool and dry stalks, lined with dry grass and root-fibres. The eggs 

 are four to seven in number, and though they vary a good deal in colour, 

 they always illustrate the peculiar tendency of the eggs of the Shrikes to 

 show a sort of zone or girdle, due to the agglomeration of the spots about 

 some part of the circumference. They are yellowish or greyish white, and 

 the spots of grey and light brown. 



42. FIELDFARE. 



I have sometimes seen this favourite game-bird of the school-boy here as 

 early as the latter part of September, and I have frequently noticed them 

 feeding in hundreds on the holly berries which abound in more than one 

 part of this district. They must breed very late in the year from the late 

 period of their departure hence, and the distance of the countries to which 

 many of them resort for that purpose. It breeds very abundantly in Nor- 

 way, and also in Sweden, Russia and Siberia, not to mention other and more 

 southerly countries in Europe. Their nests, in Norway, are usually built 

 against the trunk of the spruce-fir, and at very variable heights from the 

 ground. They are said to be very like those of the Ring Ouzel, except that 

 small twigs are added to the outside structure. The eggs are from three to
