BIRDS FREQUENTING CITKTTS GROVES. 



The citrus groves of Porto Rico are growing steadily in extent, 

 and it is of vital interest to the growers that birds accept the new 

 conditions brought about and make the orchards regular feeding 

 grounds. Rumors that a bird injured the fruit by puncturing it could 

 not be substantiated. A few birds, as the oriole and spindalis, were 

 seen eating oranges, but in every case they attacked only wild fruit 

 that was dead ripe and beginning to soften. The honey creeper, too, 

 came to sip the juice when the oranges were once broken open. Quail- 

 doves pecked open the rotting sweet oranges for the seeds as they 

 lay on the ground, but no birds were found attacking sound fruit in 

 the groves. Insectivorous species in feeding about the trees destroy 

 innumerable pests and assist in keeping the trees clean. The open 

 spaces and shady perches found are attractive to a number of birds, 

 and when nests are built in the orchards care should be taken not to 

 disturb them. Many birds now finding shelter in brushy areas sur- 

 rounding the groves resort to the orchards to feed during the day.
