COCCYZUS. 525 
Costa Rica, it is found as high as 6000 feet in the mountains. He remarks that birds 
from the Atlantic coast seem to be decidedly the darkest, those from the Pacific coast 
considerably paler, while specimens from the interior are palest }. 
We never met with it in Guatemala, but it has been recorded from all the other 
Central-American States, as well as from Eastern and Western Mexico. 
Its breeding-habits, as described by Brewer+, resemble those of C. americanus. Its 
nest is a very slight flat structure of twigs, and the eggs, usually three in number, are 
oval and of a glaucous-green colour. 
Two other forms of C. minor have been recognized in the bird of the Bahamas, 
which is the C. maynardi of Ridgway, and the Dominica bird, which Capt. Shelley has 
called C. dominicw. The differential characters of the three forms are given on 
plate xii. of the ‘Catalogue of Birds’ ™*.
