"They inhabit the densest forests and thickets, spending much of 

 their time upon the ground, turning up the leaves with their bill in 

 search of insects." 



20. Turdus flavirostris Swain. "Mexican Robin ; Merulin." 

 In general appearance this thrush resembles its allied species 



(Turdus migratorius),tke common robin of the United States, and 

 like that bird is also partly migratory in its habits. They frequent 

 the Islands in great numbers, and become excessively fat upon the 

 various kinds of berries which they find in abundance in the Marias. 

 They also breed there. This bird is common on the main land, in 

 the vicinity of Mazatlan, Tepic y Bendaras Bay, Colima and 

 Tehuantepec. 



"Prof. Baird says this species is but little known to ornithologists 

 at the present time, none having been obtained by Boucard, Salle 

 DeOca and other collectors. I have sent specimens from the Marias 

 and main land. 



"Iris, reddish brown, feet brown. Total length of adult male, 

 9.30; alar ext., 15 in.; tail, 4 in.; tarsus, 1.15; bill, measured from 

 forehead, .75 ; third primary quill longest. 



"There is but little difference in the color of the sexes." 



21. Turdus grayi, Bp. " Grey-breasted Robin, Merulin." 



"Is a resident of the Tres Marias, as well as in some localities on 

 the main shore. I procured specimens near Tepic at the beautiful 

 hacienda of Iauja, belonging to Barron and Forbes, in the months 

 of April and May ; they were in full song then, and commencing to 

 build their nests among the orange and mango groves that so 

 handsomely ornament the grounds of Iauja. One was here kept in 

 a cage and its melodious whistling notes could be heard for some dis- 

 tance. Their song somewhat resembles the northern robin (Turdus 

 migratorius) but is more voluminous. 



"The Marias and Tepic are the only localities I saw this thrush ; 

 it is however, doubtless much more widely distributed." 



22. Turdus ustulatus Nutt. "Wood Thrush ; Merulincillo." 

 "I found this little thrush in the month of January, quite abun- 

 dant in the thickest of the woods of the Tres Marias. It is very 

 timid and shy, more so than any bird I saw upon the Islands ;• it 

 frequently uttered a low plaintive whistle, and seemed solitary in its 

 habits. I am unable to state whether it is a constant resident upon 

 the Islands, or only a migratory visitor. 



"Special Characteristics. Third and fourth quill longest, (counting 

 the spurious one) ; tail nearly even, or but slightly rounded. Upper
