Carnegie Museum: Escazu, Aug. 13, 1902 (Carriker). One female. 



A rare winter visitor in the highlands. There is no certainty that all 

 the references cited above refer to this bird, a portion possibly belonging 

 to S. n. notabilis, for which I have one record. However, since many are 

 authentic specimens of true noveboracensis, and since I know of but a 

 single specimen of notabilis from Costa Rica, it is probably better to place 

 all Costa Rican references under this subspecies.

This is the only authentic record for Grinnell's Water-thrush for Costa 



Rica.

(Carriker). Two skins. 



This species seems to be a little more plentiful than the two preceding, 



and is fairly abundant in the Caribbean lowlands, especially during 



September and October. After that it disappears, probably moving 



farther south. 



608. Seiurus aurocapillus (Linnaeus).
