ble most nearly those of the Ring Ouzel ; tlie outside is com- 

 posed of sticks, and coarse grass and weeds gathered wet, mat- 

 ted together with a small quantity of clay, and lined with a 

 thick bed of fine dry grass ; none of them yet contained more 

 than three eggs, although we afterwards found that five was 

 more commonly the number than four, and that even six was 

 very frequent ; they are very similar to those of the Black- 

 bird, and even more so to the Ring Ouzel ; indeed, so closely 

 do the eggs of the three species resemble each other, that a 

 drawing of any one might apply to the whole. Fig. 1, of the 

 Plate, shows the commonest variety of the egg of the Field- 

 fare ; it is also often found like Fig. 2 ; Fig. 3, a variety of the 

 King Ouzel ; Fig. 4, its most frequent colouring. The Field- 

 fare is the most abundant bird in Norway, and is generally 

 diffused over that part which we visited, building, as above 

 noticed; in society, 200 nests, or more, being frequently 

 within a very small space. 



TURDUS TORQUATUS. (linn.) 

 Ring Ouzel. 



The Ring Ouzel breeds in most of our wild mountain dis- 

 tricts, at a distance from human habitation ; its nest is very 

 similar to that of the Blackbird, being outwardly composed 

 of coarse grasses, with a slight layer of clay, and thickly lined 

 with fine dry grass ; it is most usually built upon a ledge of 

 rock ; the eggs are four or five in number, and as shown in the 

 plate, resemble very nearly those of the Fieldfare and Black- 

 bird. I have never known the eggs of the Blackbird assume the 

 markings of Figs. 2 and- 4, this being the only specific dif- 

 ference between the eggs of the three species. — Figs. 1 and S 

 may apply alike to all.
