Proceedings of the Fifth 
obtained by Dr. Lorentz in New Guinea, amongst which 
were examples of some species not yet described ; and 
Oberlebrer W. Capek on a large series of Cuckoo’s eggs, of 
which he possesses six hundred specimens. 
Migration was very fully discussed in the second Section. 
Hitter von Tschusi zu Schmidhofen was unfortunately pre¬ 
vented by illness from attending the Congress, but sent a 
paper on the incursion of Crossbills in 1909. Dr. Hugo 
Weigold, of Heligoland, proposed to establish a Bird- 
observatory on that island, on the same lines as that of 
Bossittcn, and gave a description of the island as it was in 
Gatke’s time and as it now is. Capt. von Lucanus went fully 
into the question of the altitude which birds attain on 
migration, and stated his opinion that they do not travel at so 
great a height as had been surmised by Gatke. Director Otto 
Herman gave particulars of the work done by the Boyal Hun¬ 
garian Ornithological Bureau of Budapest, and Dr. Bossier, 
of Agram, gave an account of what has been done by the 
Croatian Ornithological Bureau. Dr. Thienemann, the 
Director of the Observatory at Bossitten, contributed par¬ 
ticulars of the results obtained by marking different birds 
in order to ascertain their routes of migration, and where 
they go to in the winter. Dr. Jacob Schenck gave details 
of the investigations carried on at Budapest respecting 
migration, and remarks on the same subject were made by 
other Members. 
Bird-protection was most fully discussed by Mr. Dutcher, 
Mr. James Buckland, Dr. Borig, Dr. Heuss, and others, and 
Dr. Heuss and Mr. Buckland strongly advocated the necessity 
of establishing an international union for bird-protection in 
all countries. Frau van Hoorde spoke of ladies’ fashions with 
regard to bird-protection, and Professor Schillings urged 
strongly the advisability of prohibiting the importation of 
the skins and Bathers of birds for decorative purposes. 
After considerable discussion it was finally decided to con¬ 
stitute a permanent International Union for the protection 
of birds on civilized countries, and the following members 
were elected to serve on it:— Austria , Professor Schweder ;
