444 NKSTS AND EGGS OF 



115.1 Sula brewsteri Goss 



Brewster's Booby. 



Hab. Islands of the Eastern South Pacific Ocean, northward to Lower California. 



This is another new species of Booby which was found breeding 

 by Colonel Goss on San Pedro Martir Isle in the Gulf of California. 

 The birds were not wild, but their nesting places, as a whole, were 

 not in as exposed situations as those of the Blue-footed ; they seemed 

 to prefer the shelves and niches on the sides of the rocks. They lay 

 two eggs, and in all cases collect a few sticks, sea- weed, and often old 

 wing and tail feathers ; these are generally placed in a circle to fit the 

 body, with a view, it was thought, to keep the eggs that lie upon 

 the rock from rolling out. There is but little material on or about the 

 isle out of which a nest can be made. Colonel Goss says the birds 

 must commence laying as early as the loth of February, as young were 

 found in many cases from half to two-thirds grown. The average 

 measurement of seventeen eggs is given as 2-44X 1.60. In color and 

 form, as well as size, they are similar to the eggs of the Blue- 

 footed, in fact so nearly alike that when placed together they cannot 

 be separated with certainty. A set of two is in Captain Goss' cabinet. 

 These measure 2.40 x 1.70, 2.3OX 1.62 respectively.

American Flamingo. 



Mr. D. P. Ingraham, who has collected a large number of these 

 handsome birds in the West Indies and spent more or less of his 

 time for four seasons among them, has given me the following inter- 

 esting notes concerning their nesting : 



He states that the birds inhabit the shallow lagoons and bays 

 having soft clayey bottoms. On the border of these the nest is made 

 by working the clay up into a mound which, in the first season is per- 

 haps not more than a foot high and about eight inches in diameter at 

 the top and fifteen inches at the base. If the birds are unmolested 

 they will return to the same nesting place from year to year, each sea- 

 son augmenting the nest by the addition of mud on the top, leaving a 

 slight depression for the eggs Mr. Ingraham speaks of visiting the
