and west to east flight, and supports a coastwise 

 migration for this species. 



Adult teal, captured in decoys, ringed and re- 

 leased in South Denmark in September and October, 

 were taken in November and December in Hamp- 

 shire, Suffolk and the Moray Firth, whilst others 

 from the same place were recorded from other parts 

 of England and Ireland, from western France, 

 Holland, the south of Spain and the north of Italy. 

 Fly-lines, if followed, are divergent and complicated. 

 Four young herons were marked in one nest in 

 Denmark ; one was recorded in Holstein in June, 

 and another in Mecklenburg in July ; the third 

 was killed near Salisbury in Wiltshire in October, 

 and in the following February the last was obtained 

 in the north-west of France. Two from another 

 nest were recovered in Denmark, one in July and 

 the other in Februarv, twelve months after birth.

 value of the method and the present insufficiency of 

 results. 



Many of these records show that the speed of 

 the migrating birds, even in spring, is not great. 

 Mr Cooke proves that most species in North America 

 travel slowly through the districts where food is
