true " Sap-suckers," which have brought all Woodpeckers into 

 ill repute among American farmers. They almost always fre- 

 quent live trees, and feed upon the soft inner bark itself rather 

 than upon insects. Colaptes wexicanus is very common here. 

 The tongue in this genus is capable of protrusion far beyond that 

 of any other North American Woodpeckers. 



Selasphurus rufus is very abundant here in summer, and until 

 October. I think I have also S. platycercus in my collection. 



I have not yet detected Panyptila melanoleuca at Fort Whipple, 

 but on the road, just after crossing the Zuni Mountains, I saw 

 great numbers of them about some high cliffs, in company with 

 Bank- and Cliff-Swallows. I shall doubtless find the species here. 



Ceryle alcyon I have once seen. 



Tyrannus vociferans is very numerous as a summer resident, 

 breeding abundantly. Early in October it left us entirely, as did 

 Myiarchus mexicanus, which is also very common. Sayornis smjus 

 is rare. Contopus richardsoni, or at least the species I noticed in 

 the E,io Grande and took for that, is a summer resident exceed- 

 ingly abundant. Empidonax pusillus is rather rare, while E.flavi- 

 ventris var. difficilis is common. Of Pyrocephalus rubineus I have 

 one specimen. Myiadestes townsendi andPhanopepla mVms are rare. 



Oi Hylocichla nana one specimen has been obtained. Planes- 

 ticus migratorius is common in spring and fall. Sialia mexicana 

 is very abundant, while S. arctica is much less numerous. In 

 autumn Regulus calendula is very common. 



Anthus ludovicianus is abundant in the fall. 



Geothlypis trichas is common, but G. macgillivrayi rare. 

 Ideria longicauda is a summer resident, and not uncommon. Of 

 the Warblers we have Dendrceca auduboni, D. townsendi, D. occi- 

 dentalis, and D. nigrescens. The first I only found after autumn 

 had set in ; the last three are among the summer birds, D. ni- 

 grescens being the rarest. D. astiva is undoubtedly to be found 

 here, and perhaps D. virens and D. superciliosa also, Myiodioctes 

 pusillus is very common. 



Cotyle serripennis is not uncommon. Hirundo lunifrons, Herse 

 thalassina, and Progne purpurea are abundant. The last two in 

 this country live among high pines, and nestle in old Wood- 

 peckers' holes.
