BIRD NOTES PORTUGAL
Coverley, H. W.
Based on his field observations made in the 1930's and early 1940's, Henry Waldo Coverley produced an undated manuscript under the title "Bird Notes - Portugal".
Coverley's work is a major reference for Portuguese ornithology and indeed it has been quoted many times in several works on the birds of Portugal, as an undated manuscript. The present edition accurately reproduces Coverley's text.
