THE MANGROVE CUCKOO
CoccYZUS Seniculus, Nuttall.
PLATE CLXIX. Male.
A few days after my arrival at Key West in the Floridas, early in the month of May, Major Glassel of the United States' Army presented me with a specimen of this bird, which had been killed by one of the sol- diers belonging to the garrison. I had already observed many Cuckoos in the course of my walks through the tangled woods of that curious island ; but as they seemed to be our Common Yellow-billed species, I passed them without paying much attention to them. The moment this specimen was presented to me however, I knew that it was a species un- known to me, and thought, as I have on many occasions had reason to do, how vigilant the student of nature ought to be, when placed in a country previously unvisited by him. The bird was immediately drawn, and I afterwards shot several others, all precisely corresponding with it. The habits of the Mangrove Cuckoo I found to be much the same as those of our two other well known species. Like them, it is fond of suck- ing the eggs of all kinds of birds in the absence of their owners, and also feeds on fruits and various species of insects. It is, however, more vigi- lant and shy, and does not extend its migrations northward beyond the eastern capes of the Floridas, appearing, indeed, to confine itself mostly to the islets covered with mangroves, among the sombre foliage of which trees it usually builds its nest and rears its young. It retires southward in the beginning of September, according to the accounts of it which I received in the country.
The nest is slightly constructed of dry twigs, and is almost flat, nearly resembling that of the Yellow-biUed Cuckoo, which I have already described. The eggs are of the same number and form as those of that species, but somewhat larger. It raises two broods in the season, and feeds its young on insects until they are able to go abroad.
The White-headed Pigeon is frequently robbed of its eggs by this plunderer, and it is alleged by the fishermen and wreckers that it destroys the squabs when yet very young, but I saw no instance of this barbarous propensity. One which had been caught in its nest, and which I saw placed in a cage, refused all kinds of food, and soon died. This, however
