971, or 3.3 per cent. This, I think, must be considered 

 a very good percentage on so large a total, but of course

 really valuable recoveries is less than 3 per cent. On 

 the other hand this percentage is certain to increase 

 in the course of a few years. 



The proportion of recoveries of different species varies

 details of a few of those species of which we have ringed 

 large numbers will perhaps be interesting : —
