Dendroica aestiva rubiginosa (Pallas). Alaskan Yellow Warbler. 



Several of these birds were taken aud others seen about the settle- 

 ment on Maria Madre. They were evidently stray migrants, and most 

 of them left before the end of May. 



Dendroica aestiva morcomi Coale. Western Yellow Warbler. 



Among the yellow warblers taken on Maria Madre during the first 

 half of May were two specimens referable to Dendroica wstiva morcomi. 

 Like rubiginosa, they were stray migrants which had wandered out of 

 their course while en route to their more northern breeding grounds. 

 They were found about weed patches and shrubbery in the settlement. 



Dendroica auduboni (Townsencl). Audubon's Warbler. 



Two of these birds were seen during the first half of May about the 

 settlement on Maria Madre, and May 30 a specimen was taken on 

 Maria Cleofa. Like the yellow warblers, they occur merely as stray 

 migrants and were seen only near the seashore. 



Dendroica townsendii (Townsend). Townseud's Warbler. 



Two or three of these warblers were seen at the settlement on Maria 

 Madre between the 8th and 20th of May. They kept about the Aveed 

 patches and yards for several days, and were stray migrants like the 

 preceding species. 



Granatellus francescae Baird. Tres Marias Chat- Warbler. 



Granatellus francescce Bair l, Rev. Am. Birds, p. 232, 1865; Grayson, Proc. Boston 

 Soc. Nat. Hist., XIV, p. 278, 1871; Lawr., Mem. Boston Soc. Nat. Hist., II, p. 270, 

 1874. 



These beautiful birds were seen only on Maria Madre, but they prob- 

 ably occur also on Maria Magdalena, where the conditions are equally 

 favorable. They were far from common, and inhabited the forest on 

 the higher slopes, but two or three individuals, evidently wanderers, 

 were encountered in the scrubby forest near the shore. They were 

 usually seen on the ground searching for food among low underbrush 

 and weeds. In such places they ran about among the thick stems of 

 plants and matted undergrowth, springing up every now and then to 

 a twig or weed stalk a foot or two from the ground, and then perhaps 

 flitting along from stem to stem to another feeding place a few yards 

 away. When thus passing through the undergrowth, they are very 

 conspicuous and attractive objects, owing to their beautifully contrasted
