LÖNNBERG AND RENDAHL, ORNITHOLOGY OF ECUADOR. 9 



The letters behind the names, which indicate the distribu- 

 tion, have the same meaning as in the former lists. They 

 prove in a very interesting manner, that the bird life of the 

 subtropical zone of the western side of the Andes of Ecuador 

 has very many forms in common not only with the fauna of 

 western Colombia, but also to a very great extent with the 

 same of the central, or Cauca-Magdalena district of Colombia. 



A number of the species here enumerated among the 

 subtropical members of the fauna live near the boundary 

 line between the subtropical and temperate zones, so thab 

 they might perhaps be referred just as well to one as to the 

 other of these, although we have our specimens from the 

 subtropical zone. Such are for instance Penelope montagnei, 

 Iridornis duhusia ignicapillus, Hemispingus superciliaris nigri- 

 fröns, and some others. In other cases the range of the species 

 extends very plainly through more than one zone, as well 

 according to Chapman's records as our own experience. With 

 regard to some birds again there is a certain discrepancy as 

 to their occurrence. Chapman records f. i. Patagona gigas 

 as characteristic for the Puna zone in Peru, while our specimens 

 are from an altitude of 6000 to 9000 f. The foUowing species 

 are according to Chapman members of the temperate fauna, 

 but we have found that they range very deep down into the 

 subtropical zone f. i. Ciccaba albogularis (to 6000 f.), Vesti- 

 pedes vestitus smaragdinipectus (to 7000 f.), Thripadectes flam- 

 mulatus (to 7000 f.), Mecocerculus stictopterus (to 6000 f.), 

 Procnopis vassori (to 6000 f.), and Psittospiza riefferi (to 5500 f.), 

 while we have no records of these species from the temperate 

 zone. 



Some of the birds, which Chapman registers as tropical, 

 we have from the lower parts of the subtropical belt near the 

 boundary line as f. i. Golumha goodsoni, Ärdea cocoi, Ciccaba 

 virgata virgata, Machaeropterus deliciosus, and Henicorhina 

 inornata from an altitude of approximately 5000 f . ; and Flori- 

 suga mellivora and Myiobius erythrurus fulvigularis from 

 6000 f. It is also not astonishing to find that some birds, 

 which are bound to water like Carbo vigua and Ceryle amazona 

 extend their wanderings along the water courses high up to 

 an altitude of 9000 f . from their regular habitat in the tropical 

 zone. It is likewise no wonder although worth noticing, 

 that some birds of prey like Circus cinereus (5000 — 12000 f.),
