t)f canoe navigation on the first-named stfeam, and remained there until 

 March 21. Two days later he reached Buenaventura where he was joined 

 by Chapman, Fuertes and Miller. 



The whole party now went to Call, and after depositing there a large 

 part of their equipment and supphes, established themselves, March 29, 

 very comfortably in a bungalow at San Antonio, immediately below the 

 forest which crowns the crest of the mountain. The collections made by 

 us here in connection with those of Palmer, are believed to contain a large 

 proportion of the birds which occur in this locality. 



April 8 we returned to Cali and on the 11th reached the sugar estate of 

 La Manuelita in the Cauca Valley, some five miles north pf Palmira. Here 

 we were the guests of Mr. Charles J. Eder until the 18th, when with pack 

 animals supplied by Mr. Eder, we moved to his bungalow, Miraflores, situ- 

 ated on the western slope of the Central Andes, about 3000 feet above the 

 valley, or at an elevation of some 6100 feet. 



May 1, Mr. Eder sent mules for us and, after a night at La Manuelita, 

 we crossed the valley to Cali by way of Florida and Guengiie, stopping at 

 the last-named ranch two days and reaching Cali on May 7. 



Some collecting was now done in the marshes of the Cauca River near 

 Juanchito, the port of Cali. Fuertes secured here our first specimen of 

 Aythya nationi, a practical rediscovery of the species previously known 

 only from a pair taken at Lima, Peru. 



May 13, Fuertes and Chapman began their return journey to New 

 York in a reconnaissance down the Cauca to Cartago, thence over the 

 Quindio Pass to Giradot on the Magdalena, and down that river to Barran- 

 quilla, which was reached June 4. 



On the same date Miller and Richardson left on all expedition to the 

 Andes west of Popayan. 



On the whole, the work of this first expedition is believed to have given 

 us a fair idea of the avifauna of the region covered. We regret now, how- 

 ever, that no attempt was made to reach the Farallones of Cali, the highest 

 point in the Western Andes, between the summit of the Micai Trail, west 

 of Popayan, and the Citara of Antioquia. With an altitude of between 

 9000 and 10,000 feet, it is possible that we might have found there some 

 species of the Temperate Zone. Our Cauca Valley collections would also 

 have been more satisfactory if we had explored' a tract of primeval forest 

 between Cali and Florida. 



Description of Route and Collecting Stations. — The rainfall of the Pacific 

 slope of Colombia is phenomenal. It has been known to reach 400 inches 

 in one year at San Jos^ (see beyond). There is no dry season on the Pacific 

 coast and it rains almost daily in this intensely humid belt.
