Era la stagione della vendemmia per lo Jabiru, l'Erone, il Vulture e l'Opossum, e stavano godendo la loro festa periodica al massimo. Mi è stato detto che il cacciatore di plume ha l'abitudine di raccogliere quantità di questi pesci, avvelenarli, e poi spargerli in onda sui terreni di alimentazione di Heronsfeeding. Occasionalmente, i gamberetti avvelenati sono usati, se gli inundationsestendono oltre il tempo usuale. Questo metodo è naturalmente più conveniente che sparare: Gli uccelli non sono

. Bird-lore . drying-up process continues, the stranded fishdie in heaps. I saw tons of them—dying, dead and decaying—in the pan-tanales on the Taquary. It was the season of harvest for the Jabiru, Heron, Vulture and opossum, and they were enjoying their periodical feast to the full. It is the custom of the plume-hunter, I was told, to collect quantities ofthese fish, poison them, and then scatter them broadcast over the Heronsfeeding-grounds. Occasionally, poisoned shrimp are used, if the inundationsextend beyond the usual time. This method is of course cheaper than shooting:the birds are not frightened away, and the results of such relentless persecu-tion must be obvious. A whole colony may be exterminated in its feeding-grounds, even if the rookery is impregnable. I do not know to what extend this process of extermination is carried on.I have never seen it in operation, and had never heard of it elsewhere. Butsuch, my informant assured me, are the methods employed on the Madeiraand Solimoens.. MOURNING DOVEPhotographed by Guya Bailer, Geneseo, N, Y. Comparative Abundance of BirdsA Letter from Abbott H. Thayer Editor of Bird-Lore: I send you herewith a letter from Professor Munsterberg. Having long believed that our common birds are not widely diminishing, except in certain special cases where circumstances of civilization have ceasedto sustain them at an artificial abundance (as in the case of Swifts and BarnSwallows), I asked Prof. Hugo Munsterberg, the Harvard Professor ofPsychology, to corroborate my belief that circular question-lists sent about togather the public opinion on this subject are dangerous and misleading, because of the very psychological reason that he gives in the accompany-ing letter. His answer sent you herewith should influence all the local Audubon Socie-ties who publish such dismal annovmcements. These Societies will swiftlydiminish their own credit by such an unscientific position. Let me here say that I go annually over my boyhood stamp
