south, but solitary examples are now and then met 

 with during November. 



The specimens in the case were shot in the Firth 

 of Forth in August and September, 1874. 



GEE AT CRESTED GREBE. (MATURE AND 

 HALF-GROWN YOUNG.) / 



Case 255. 



The present case shows the young Loons* between the 

 age of four and five weeks. 



It would hardly be supposed that a Perch of two or 

 three inches long, with its prickly fin, would be a plea- 

 sant mouthful for a young bird of this age ; the 

 smaller specimen, however, contained a couple of fish 

 of that length, while the larger had only a few feathers 

 in its stomach. 



The old and young were obtained on Hickling Broad 

 in June 1873. 



GREAT CRESTED GREBE. (IMMATURE.) 

 Case 256. 



The specimens in this case are probably from ten to 

 twelve weeks old. 



While in the down the eye of this species is a 

 light grey. During their first autumn and winter I 

 have observed the iris both a dull orange and a bright 

 lemon yellow ; this gradually changes till it assumes the 

 brilliant red which is seen in the adult in summer. 



The birds were shot on Breydon, near Yarmouth, in 

 September, 1871. 



* Norfolk name for the Great Crested Grebe.
