TANAlilUD^E — THE TANAGEUS. 445 



diU'ereut lioin the throat, and abruptly Hfjhtrr than tlie hack, wliich, wiili the \vin<rs 

 and tail, is of a much lij^'iiter «lusky-rt'<l than in cfsfiva ; exposed tips of primaries pme 

 slaty-umber, primaries faintly margined terminally with paler (in the tyjte, this char- 

 acter is not apj)arent, owinir to the feathers beinir somewhat worn; in other specimens, 

 however, it is (juite a noticeable fe.^ture, althon^di possibly not to bi; entirely relied on). 

 Female. Abov; oran^'c-olivaceous, beneath more li<^ht yellowish, purest medially; cris- 

 suni richer yellow than other lower parts, bfing in some individuals (younj; mali's?) 

 intense Indian-yellow, with the inner wel>s of the tail-feathers margined with the same ; 

 quite distinct line of orange-yellow over the lores. 



IIab. Upper Hio Grande and Colorado region of Southern Middle Province; south, in 

 winter, along Pacific coast of Mexico as I'ar as Culima. 



This bird, quite different from Eastern ccstiva, is, liov.ever, probably only a 

 representative form of the same species in the Colorado and Upper llio 

 Grande region, migrating south in winter, througli AVestern Mexico to 

 Colima, as specimens from Texas and Middle Mexico appear to be quite 

 intermediate, at least in form. 



Habits. This is a new form, whose claim to distinctness was first made 

 known by Mr. Ridgway, in 18G9. In a])pearance, it most resembles the P. 

 cestiva, but is larger. It has been found in the Middle Province of the United 

 States, from Fort Mohave at the nortli, to Uolima and Mazatlan in Mexico. 



Dr. Cooper found this bird quite common near Fort Mohave, after A]>ril 

 25, in the Colorado Valley, latitude 'M}°. They chiefly frequented the tall 

 Cottonwood, feeding on insects, and occasionally Hew down to the Lama 

 bushes after a kind of bee found on them. He states also that they have 

 a call-note sounding like the words kc-iiik, which, in the language of the 

 Mojave Indians, signifies "come here." They sing in a lotul, clear t<me, and 

 in a style much like that of the Kobin, but with a power of ventriloquism 

 which makes the sound appear much more distant than it really is. The 

 only specimens of this si)ecies known to have been obtained in tiie United 

 States were taken at Los Pinos, Xew Mexico, by Dr. Coues, and at Fort 

 Mohave by Dr. Cooper. Other specimens have been procured from Western 

 Mexico.
