stated, are: (1) Six noddies, "marked characteristically and individually 

 with oil paints," were put on board the laboratory launch bound for Key 

 West; two, liberated when 19.5 statute miles distant, returned to their 

 marked nests in 2 \ hours after they were released; two were liberated 

 at a distance of 44.75 statute miles and returned to their nests in If hours 

 after their release; two were liberated at Key West, 65.8 statute miles 

 distant, and reached their nests, one 11 hours later and the other about 23 

 hours later, night intervening when the birds probably did not attempt 

 to fly. 



(2) Three noddies and two sooties, captured and marked, and their 

 nests likewise marked, were taken, June 13, via Key West, to Cape Hat- 

 teras and liberated 12 miles east of the Cape. Several days after the 

 marked sooties were found at their nests, and a few days later one of the 

 noddies was seen attempting to alight on its nest, but its mate, having 

 formed new 'affiliations', this was not permitted. Dr. Watson states 

 that he has no doubt the other two noddies returned to the island and 

 were likewise not permitted to return to their nests. The distance in a 

 direct line from Bird Key to Cape Hatteras is about 850 statute miles, and 

 by way of the coast about 1080 statute miles. The birds were thus taken 

 hundreds of miles to the northward of their normal range, yet were able to 

 return quickly to their nests on Bird Key. 



(3) On July 8, two noddies and two sooties, marked for identification, 

 were taken to Havana; they were released on the 11th, and reached Bird 

 Key on the following day. The birds were in such poor physical condition 

 from the strain of caring for their nearly full-grown young that it was de- 

 cided not to take them further away before releasing them. 



In the present connection there is space merely to call attention to Dr. 

 Watson's interesting experiments with young terns in learning the 'prob- 

 lem box' and the 'maze,' which are of special interest to the psychologist 

 rather than to the ornithologist. Dr. Watson's paper, as amply shown 

 above, is noteworthy from the double viewpoint of ornithology and 

 psychology; it is a detailed and continuous study of the activities of two 

 species of a very interesting group of birds during nearly the entire season 

 of reproduction. The accompanying eleven plates illustrate the nesting 

 attitudes of the old birds, young of various ages of both species, groups of 

 nesting sooties, flashlight pictures, to show the possibility of studying the 

 behavior of the birds at night,the character and grouping of the nests of 

 the noddies, and the group activities of both sooties and noddies. — J. A. A.
