. A popular handbook of the ornithology of eastern North America . Cow Troopial sometimes deposits her egg, andleaves her offspring to the care of these affectionate and pigmynurses. In this case, as with the Cuckoo in the nest of theYellow Wren and that of the Red-tailed Warbler, the egg isprobably conveyed by the parent, and placed in this small andslender cradle, which would not be able to sustain the weightor receive the body of the intruder. Though classed with the Flycatchers by Nuttall and other writersof his day, this species is now ranked as one of the highest types ofthe Oscines, or Singing Birds, and a sub-tamily has been made forthis and the two Western forms. Mr. William Saunders finds thepresent species fairly common near London, Ontario, but it is onlycasual in New England, and is rarely seen north of latitude 42°.It winters in the Gulf States and southward. Mr. Chapman tells us that this bird has an exquisitely finishedsong, but the voice is •• possessed of so little volume as to be in-audible unless one is quite near the singer.. YELLOW-BREASTED CHAT. ICTERIA VIRENS. Char. Above, olive; lores black; throat and breast rich yellow ;belly white. Length 7 to 8 inches. AtjA In a thicket 2 or 3 feet from the ground ; of dried leaves, stripsof bark, or grass lined with fine grass or fibres. Eggs. 3-4; white, with pink tint, spotted with brown and lilac ; 0.9cX 0.70. This remarkable bird is another summer resident of theUnited States which passes the winter in tropical America, being found in Guiana and Brazil, so that its migrations prob-ably extend indifferently into the milder regions of bothhemispheres. Even the birds essentially tropical are stillknown to migrate to different distances on either side theequator, so essential and necessary is this wandering habit toalmost all the feathered race. The Icteria arrives in Pennsylvania about the first week inMay, and does not usually appear to proceed farther north andeast than the States of New York or
