THE CONDOR

A. macao), parrots ( Amazona virenticeps and A . salvini, Pionus senilis and Piono- 
psitta haematotis), and parrakeets ( Conurus finschi ) were exceedingly numerous, as 
were also two large toucans ( Ramphastos tocard and R. brevicar hiatus), two smaller 
toucans, the common Pteroglossus torquatus and rare Selenidera spectabilis , being 
less abundant. Four species of trogons ( Trogon massena, T. clathratus , T. caligatus 
and T. tenellus) were common, and smaller birds almost without number. We es- 
timated the total number of species to be found in this locality at not less than 
four hundred. Every day were heard many species of which we were not able to 
get even a glimpse, owing to the dense vegetation and difficult ground of the 
places which they frequented. At this place we witnessed a flight of migrating 
hawks, passing northward, which comprised hundreds of thousands of individuals. 
They were a small species (about the size of Buteo latissimus or B. br achy urns), 
most of them light colored underneath but many of them wholly dusky in color; 
whether there was more than 
one species we were not able 
to determine. The resident 
hawks at Bonilla were appar- 
ently few in number, the 
most numerous being the 
swallow-tailed kite (which by 
the way breeds there,*), next 
in order being Rupornis rufi- 
cauda and the beautiful snow- 
whit eLeucopternis ghiesbrcchti. 
One example of the rare 
ground cuckoo, Neomor phus 
salvini , was obtained, and 
also a single male of the beau- 
tiful white cotinga, Carpod- 
ectes nitidus, shot by our taxi- 
dermist, Adan Lizno, from a 
small company which alighted 
in the “laurel" trees inside 
the corral close by the house. 
A single umbrella bird ( Cepha - 
lopterus glabricollis) was se- 
cured by Alfaro, being the 
only one seen; and on the 
GREAT EXCITEMENT OVER REDISCOVERY OF GUAYASTICUTUS CORYI 
higher potreros the Costa 
Rican bell-bird, Procnias tricaranculatus , was occasionally seen or heard, and I had 
the pleasure (?) of shooting a fine male from the top of a very high tree and after 
watching it fall straight down for a hundred feet or more see it lodge among some 
air plants thirty feet up, where I could not possibly get it. The note of this bell 
bird is most singular, sounding like a heavy stroke with a hard mallet on a hollow 
log of hard wood, followed immediately by a wonderfully loud, clear and prolonged 
whistle — both easily heard at a distance of half a mile or more. 
Not the least fascinating part of our experience at Bonilla was the shooting of 
hummingbirds from the flowering guava* trees. These trees are small, open, and 
a Ou several occasions we saw them pulling long moss ( Tillandsia) from the trees and carrying it to the nests 
they were building in tall trees on the potrero. 
b Not the tree which bears the fruit guavava, so universally mispronounced “guava.”
