I TO Brewster and Chapman on Birds of the Sutvanee River. [April 



A regular flight of Little Blue Herons, with a few Louisiana 

 Herons, began about half an hour before, and continued until a 

 short time after, sunset. The birds flew down the stream in flocks 

 of from five or six to fifty or seventy-flve individuals each, mov- 

 ing in compact bodies and usually about on a level with the tops 

 of the trees. We found the objective point of this flight to be a 

 small treeless island covered with marsh grass, near the mouth of 

 the river. Here on the evening of March 30, we saw fully five 

 hundred of these birds come in and pitch down into the grass. 

 There were also a few large Egrets among them. There was 

 nothing to distinguish this island from apparently similar ones 

 near by, but it was evident from the signs we found there that the 

 birds had made it their roosting place for a long time. 



Flocks of from twenty to one hundred and fifty White Ibises 

 were not infrequently observed during the earlier part of the 

 voyage. The birds appeared after the flight of Herons had ceased 

 and followed the course of the river either north or south evidently 

 en route to a rookery. This species was less common on the 

 lower river, indeed we observed only one flock of about thirty 

 birds which, at eight o'clock on the evening of March 30, passed 

 low over our canoes with a sudden rush of wings, their snowy 

 plumage glistening in the moonlight. A few seconds later ap- 

 parently the same flock passed us retracing its course. 



The nights on the river were more quiet than we had expected 

 to find them. When moored beneath overhanging oaks, where 

 in the early morning and late afternoon the choking bark of the 

 always abundant gray squirrels could be heard, we frequently 

 detected in the evening the fine, high, squeaky note of flying 

 squirrels. On the lower river at times a sudden chorus of frogs 

 abruptly broke the stillness and as abruptly ceased, but without 

 the Barred Owls there would have been little to interest us 

 during the night. These Owls although abundant along the 

 whole course of the river, were less numerous towards its mouth 

 than in the heavily timbered bottoms above. We heard them 

 every night and rarely failed to see one or two by daylight when 

 we were in the woods. They hooted most freely from a short 

 time after sunset until about eight o'clock in the evening, after which 

 hour they were not often heard until near morning, except 

 during moonlight nights when they hooted at all hours. It was 

 by no means uncommon to hear them during the daytime, and on
