526 CUCLTLED^. 



According to Grayson, it is a summer visitant to the neighbourhood of Mazatlan, 

 arriving in June and leaving again in September. During its sojourn it usually 

 frequents the mangrove-swamps and breeds there ^^. In other parts of the country we 

 have records of its occurrence extending from April to October, but none indicating 

 that the bird remains during the autumn and vi^inter months; the latest date recorded 

 being October 20, when Mr. Cherrie found it at San Jose, Costa Rica ^^. This confirms 

 Grayson's statement, and shows that during the winter C. americanus passes to the 

 South-American continent, where it spreads as far as Argentina, and that Central 

 America and Mexico, at least on the coast, are included in its breeding-area. North- 

 ward of our region it is, of course, a well-known bird, being found during the summer 

 from Canada to Florida and Texas, and from the Atlantic to the Pacific coasts ^. The 

 western birds from Oregon to New Mexico and Colorado are noted for their larger size 

 and stouter bill, and have been described by Mr. Eidgway as C. americanus occidentalis. 

 A specimen before us from Sonora is no doubt one of this large race, but we have not 

 been able to identify with certainty any other examples as belonging to it ; and as the 

 dimensions of the two forms, as given by Mr. Ridgway, completely overlap, we do not 

 attempt any separation. 



In the West-Indian Islands C. americanus is not uncommon, and there are records 

 of its breeding in many of the islands ^^. In Cuba, Gundlach says he met with it on 

 .few occasions in the western districts, where he found its nest ^^. Sir E. Newton also 

 met with it in the island of Santa Cruz, and describes a nest he examined at the end of 

 June 1858. This nest was a very slight platform of sticks laid across one another with 

 a few finer twigs and a little grass as a lining, but so slightly put together that on 

 attempting to take it from the tree it fell to pieces. The eggs are three or four in 

 number, oval, and of a pale green colour. 



A few individuals of this Cuckoo have strayed to Europe.
