RENDAHL, BIRDS FROM THE PEARL ISLANDS. 5 



Trapiche is a little holm, not reaching a length of oiie 

 km, off the northern shore of Pedro Gonzalez. The crown 

 of it forms a lengthened plateau about 30 m above the sea 

 level, gently sloping to the south and covered with a fine cocoa- 

 park. The hohn was inhabited. 



San José is the next largest of the Pearl Islands, being 

 13 km long (from the north to the south) and 7 km wide. It 

 is higher than the islands mentioned previously and is covered 

 with a hixuriant vegetation. Niimerous watercom^ses flow 

 through the valleys — but the island is uninhabited. 



San M i g u e 1 (or E 1 R e y ) is the largest of the islands. 

 Dr. BovALLius sailed round it, collecting on some points of the 

 coast. A rich bird-life he found at its sotithern point, Punta 

 Cocos. This jutting piece of land is 9 km long and nearly 2 

 km in width at its widest point. Along its whole length runs 

 a mountain ridge, descending abruptly at the west- and south- 

 sides, while at the east-side it slopes gently to a fertile playa, 

 or strip of shore, with a beautiful vegetation. At low tide there 

 was a very rich bird-life on the shore. At the playa there 

 was a fresh-water lagoon, which was, as Dr. Bovallius states, 

 the favourite hamit of different species of ducks. 

 On the shores of this lagoon he also signals the appearance of 

 g u a n o-h ens, döves and different 1) i r d s of p r e y . 



There is very little to be said about the rocky holms 

 and islets surrounding San M i g u e 1, most of them not be- 

 ing visited by Dr. Bovallius. 



San E 1 m o is about the size of Chapera. The southern 

 part of the island resembles Pacheca, being also a «bird rock», 

 inhabited by c orm or an t s and pelicans, the northern 

 part on the contrary slopes gently and has a rich vegetation. 



C a n g r e j o is a little rocky holm with very steep sides, 

 inhabited by a very great colony of Man-o'-War Birds. 



With regard to their bird life, we can separate the islands 

 of the Archipelago into two groups, d e s e r t r o c k-i s 1 a n d s 

 thinly wooded or without tree vegetation, and more or less 

 hilly islands wit h^tr opical for ests.
