Above the treetops of Puerto Rico flies a flock of parrots as green as their island home. . . . These are Puerto Rican parrots. They lived on this island for millions of years, and then they nearly vanished from the earth forever. Puerto Rican parrots, once abundant, came perilously close to extinction in the 1960s due to centuries of foreign exploration and occupation, development, and habitat destruction. In this compelling book, Roth and Trumbore recount the efforts of the scientists of the Puerto Rican Parrot Recovery Program to save the parrots and ensure their future. Woven into the parrots' story is a brief history of Puerto Rico itself, from before the first human settlers to the present day. With striking collage illustrations, a unique format, and engaging storytelling, Parrots Over Puerto Rico invites readers to witness the amazing recovery efforts that have enabled Puerto Rican parrots to fly over their island once again.
