NORTHERN WATER-THRUSH 171 



90. Northern Water-thrush 



Seiums noveboracensis 



Northern Water-thrushes visit the Gar- 

 den in about equal numbers with the Oven- 

 bird. The comparison is somewhat in favor 

 of the Water- thrush. The species makes its 

 appearance on about the same dates as the 

 Oven-bird. Thus the earHest appearance 

 was on May 7, in 1902. No first-comer has 

 arrived later than May 17, which opened 

 the record in 1903. In the seven other 

 years the first Water-thrush has come be- 

 tween May 9 and 13. A single bird has 

 always arrived first, and this has soon been 

 followed by others. Five came together 

 on May 15, 1905, and the same number 

 again on May 12, 1908. Four or five days 

 appear to constitute the longest time any 

 ndividuals have remained. Such a stay 

 has been made by visitants a few times. 

 The latest birds have remained variously 

 to May 20 to 27. The rather loud and clear 

 song has often been heard.
