EASILY the outstanding ornithological event in Sussex for the year 1939 was the accomplished breeding, for the first time since about 1895, of a pair of Ravens (Corvus c. corax) in a sea-cliff some miles removed from the one in which, in 1938, (?) another couple built what was, in my opinion, merely a play-nest. Regarding the expression " (?) another," I now begin to believe that in 1938 there were two pairs of this species in Sussex--that an unattached bird was about, I well knew: My reasons for the above idea are twofold. The first is that in the 1939 nest-cliff (which, not anticipating the possible presence of a second pair, I foolishly omitted to explore in 1938) are two Raven's citadels, neither in my estimation (for very weighty reasons) being a " repeat "; the second, that in July, 1938, Mr. C. E. Palmar and Captain C. Bradley and his son at a certain point of our sea-bastions saw five Ravens together--almost assuredly a brood with their parents. As against the above being a correct view, however, one must never lose sight of the fact that in 1939 the headland occupied in 1938 was deserted, though here, of course, the chances of " accidents " to the once-tenants will have to be considered. To return to the successful hatch of 1939, on May 15th I fell in with two young Ravens on " falls " beneath the homecliff, actually, indeed, all but catching one (a Peregrine nearly
