BIBDS OF PORTO RICO. 



61 



bird alone having eaten 38. Spiders were taken freely, but amount to only 

 4.08 per cent. Strangely enough, no cattle ticks were found, though it is the 

 universal belief that the ani consumes many, and from that fact indeed is de- 

 rived its generic name. 



Miscellaneous animal matter amounting to 1.45 per cent is composed of a wide 

 range of material. Fragments of a dragon fly, a dipteran, and crustacean re- 

 mains each occur once. One stomach contained a peculiar flat platelike tooth 

 from some fish, and only two contained lizard remains. The bird, shot in the 

 act of robbing a blackbird's nest, contained large fragments of eggshell.

Vegetable food.— The vegetable matter (8.7 per cent) was made up largely 

 of the seeds of the cherrylike moral (Cordia sp.), which occurred in 15 of the 

 41 stomachs. It is doubtful whether seeds themselves appeal to this bird, as 

 there were few in the stomachs which did not have a more or less pulpy ex- 

 terior. The gizzard is hardly fitted for grinding up flinty seeds and in only 

 one stomach was a trace of gravel found. In the field the birds were seen 

 eating the icaco (Chry sob alarms sp.). None of the fruits taken are in any way 

 the product of man's labor. The following seeds were identified in the stomachs : 



Whitetop (Dichromena sp.) 



Palm (Coccothrinax sp.) 



Espino (Xanthoxylum sp.) 

 Euphorbiaceae sp 



Moral (Cordia sp.) 15 



Concoinbre (Cucumis sp.) 1 



Composite sp 1 



Summary. — The judio or ani may be considered entirely beneficial, as it de- 

 stroys large numbers of highly injurious orthoptera, beetles, and caterpillars.
