254: LIST OF ALG.E, 



and incessant cries. The nests contained two or three eggs, (I did not see 

 one with four,) and were built of fiags and sedge upon the dead leaves of 

 the bulrushes, where thej were broken down and lay upon the surface of 

 the water. Some of the nests were very carefully built, and raised high 

 above the water j others were very slight, and in one instance, there was so 

 little nest, that the egg actually touched the water. 



The eggs varied exceedingly; in some the ground colour was brown, the 

 spots being of a darker shade of the same colour; others inclined to green, 

 ■with spots and blotches of reddish brown; one beautiful variety had the 

 ground colour a very light greenish white, blotched with two shades of rich 

 brown. Eggs entirely white are sometimes found. During our stay the whole 

 colony seemed on the wing, dashing around our heads, uttering anxious and 

 unceasing cries; many of them followed us, ^mobbing' most furiously to a 

 considerable distance from their nesting-place. 



There is a much larger Gallery at Scoulton Mere, near East Dereham. 

 There, as many as thirty thousand eggs are taken annually; one year produced 

 forty-four thousand. In this neighbourhood the Black-headed Gull is found 

 during the whole summer; parties from Scoulton wandering thus far in search 

 of food. The common name here is ^Scoulton Bird;' at Kollesby, they are 

 called ^Cobbs.' An authentic list of the breeding-places of this bird would be 

 interesting, and might easily be formed, if your subscribers would record such 

 as have come under their observation. 



Will you allow me to add that I shall be happy to obtain for any of 

 your subscribers who may require them, specimens of the eggs of this bird.
