nevertheless. Besides these there were the Mourning Dov^e, Say Phoebe, Ash- 
throated Flycatcher, Richardson Pewee, Woodhoiise Jay, the Desert Sparrow, Gray 
\hreo, Gnatcatcher, and House Finch, one of whose nests was found in a tree 
cactus. Later, in climbing the thousand foot bluff we found a family of Mexican 
Falcons near the top. 
With the additions these birds made to our Pajarito list and a few others noted 
between camps there were about forty species. Considering the fact that they were 
confined to a narrow strip between broad plains on which the list of birds often 
consisted of two, sometimes of one species, the forty seemed a goodly number. 
And now, thinking back over towering cliffs enlivened by moving forms and hous- 
ing ancestral homesteads and of gulches and amphitheaters below ringing with 
joyous bird songs, this brave little band of forty peopling the juniper belt between 
silent plains seems to make the real oasis of the Llano. 
THE BLI’K-THROATED HUMMINGBIRD 
By FRANK C. WILLARD 
WITH FOUR I’HOTOS 
A S I wander about among the canyons of the Huachuca Mountains, there are 
two places where I always listen for a “squeak-squeak-siiueak” repeated every 
few' minutes, the second note higher pitched than the first, and the third 
note low'er than either of the other tw'O. These tw'o places are in deep narrow can- 
yons. It w'as some time before I was able to locate the author of the squeaks. 
Finally, I located a large hummingbird, perched on a dead twig w'ell up in a fir tree.
