Consul SÖDERSTRÖM remarks, that this Buzzard generally 

 is found in the woods on the western side at Mindo, Nanegal, 

 Gualea, etc. but sometimes also near Quito. 



It is rather interesting to find, that some of these Buzzards 

 remain in Ecuador even during the northern summer, which 

 is proved by the presence of a young female the 16th of June, 

 and still more remarkable, by an old female collected the lOth 

 of July.

 6 — 7000 f.; 1 c^ Vs Piganta, western side of Mojanda, 8600 f. 

 A semiadult female collected ^7? on the southern slopes of 

 Mojanda at an altitude of 9000 f. is already black above only 

 with some narrow tips of dull rufous to the feathers, but the 

 nape and hind-neck are somewhat streaked with buffish, and 

 the concealed parts of the feathers of this region are largely 

 buffish or white. The long upper tail-coverts creamy white, 

 partly with concealed blackish central streaks. The lower 

 side buff with broad blackish central streaks, which are domi- 

 nating on the lower breast. Under tail-coverts creamy white. 

 Tail black with two ashy brown bars above, the proximal of 

 which is partly white on the inner web of the lateral tail- 

 feathers. On the lower side of the quills these bars appear 

 white, and in addition to them there are two more whitish bars, 

 more or less pronounced and formed by white spöts and mott- 

 lings on the inner webs of the tail-feathers except the middle 

 ones. Thighs mottled with rufous, buffish and dusky producing 

 an irregularly barred appearance. Wings similar to those of 

 the adult. This plumage thus represents an interesting inter- 

 mediate stage. 



R. leucorrhoa does not appear to have been recorded from 

 Ecuador before.
