526 CUCULIDZ. 
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 1°. 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 winter months; the latest date recorded 
being October 20, when Mr. Cherrie found it at San José, Costa Rica 15, 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. Ridgway 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!S. In Cuba, Gundlach says he met with it on 
few occasions in the western districts, where he found its nest'4. 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.
