Semrus novehoracensis novcbtjiacenms. — Water-Thrusli. 



On September 1, 1905, it came in with other migrating birds 

 in some numbers. In 1910 it was first seen on August 7, one in- 

 dividual was taken, another one on the 10th. another ou the 21st, 

 and on and after September 1st it was common, ranging every- 

 where among the cedars, and down upon the point in the dead 

 brush. "Squeaking" always resulted in bringing these birds within 

 a few feet of one. The opportunities afforded for comparing this 

 with the next species were improved to the extent of learning cer- 

 tain individual traits of difference. The alarm note is easily dis- 

 tinguished when once learned. 

 ScinrKs iitotacilla. — Louisiana Water-Thrush. 



Evidently breeding in 1910, in the vicinity of the swamp, it 

 was seen on September 1, 1905, and on August 18, 1908. It became 

 common ou August 28, 1910, and continued so until we left. It 

 remained more numerous in the vicinity of the swamp at all times, 

 but individuals occasionally strayed down to the point along the 

 east beach. This and the hist species could sometimes be studied 

 together from my tent door. The slightest movement on my part 

 would send them scurrjnng away. 

 Oporotim agilis. — Connecticut Warbler. 



Found only in the vegetation along the border of the swamp. 

 The records follow. August 21, 27, 29, September 1 and 2, 1910, 

 one bird ou each of the dates given. The birds kept well to cover. 

 and would not flush. 

 Oporornis pMladelphia. — Mourning Warbler. 



In contrast to the last species, this bird was found among the 

 cedar trees, either on the ground or among the lower branches. In 

 the middle of the day individuals would sometimes visit the camp 

 and feed unconcernedly as long as we remained quiet. The records 

 follow. One on each of the following dates — August 15, 27, 28, 29. 

 September 2, and two on September 1 and 8, all in 1910. 

 Gcothli/jris trichas trichas. — Maryland Yellow-throat. 



One of the commonest and most characteristic birds of the re- 

 gion of the swamp. It also ranged down the point to the limit of 

 vegetation, on the days of strong migration. It was found on all 

 visits to the island, and some individuals were singing each day. 

 In 1910 it was common up to August 23, after which only a few 

 were seen each day. Nests were not found, but there is little 

 question that the birds nested on tlie island. 

 Icteria virens mrens. — Yellow-breasted Chat. 



There was every reason to expect this bird to breed regularly 

 on the island, but the only records are August 18, 1908, and An-
