OF BRITISH BIRDS 73 



Stercorarius richardsoni, 

 Stercorarius catarrhactes,

The remaining three are more or less common winter visitors 

 to England, but are not known to visit Ireland, and the last 

 mentioned is unknown in Scotland as well : 



Alauda alpestris. 



Otis tarda (formerly breeding). 



Regulus ignicapillus. 



SPRING AND AUTUMN MIGRANTS. 



All the Spring and Autumn Migrants visit England. Three 

 appear to absent themselves from Scotland, and the same number 

 from Ireland. The number of English spring and autumn migrants 

 may be estimated at thirty-two, whilst that of Scotch and Irish is 

 only twenty-nine.. 



There are thirty-two British Birds which may be regarded as 

 Spring and Autumn Migrants, though in some cases a few indi- 

 viduals remain in autumn to winter with us and a few remain in 

 spring to breed in some part of our Islands. 



Of these species eighteen are spring and autumn migrants to 

 the three kingdoms, but do not breed in any of them : 



Coracias garrula. 

 Crex parva. 

 Scolopax major. 

 Charadrius Jiiaticula. 

 Charadrius helveticus. 

 Limosa melanura. 

 Limosa rufa. 

 Totanus fuscus. 

 Totanus ochropus. 

 Totanus glareola. 

 Strepsilas interpres. 

 Tringa siibarguata, 

 Tringa temmincki. 

 Tringa arenaria. 

 Tringa minuta.
