they seemed to prefer the beds of tall sunflowers on neglected 

 farms, though I still remarked their partiality for mesquites. 

 During the fall of 1880, when I was anxious to procure some 

 skins, I kept a special look out for these birds, but did not see a 

 single example. 



Dendececa coeonata (Linn.) Myrtle Warhler. — Arriving 

 during the latter half of October, these birds are very abundant 

 in our section from that time until the third week of March, 

 beyond which I never observed any. During the winter months, 

 they frequent the creeks and open woods, feeding in cold or 

 stormy weather upon the lower branches of trees, and even among 

 low brushwood or heaps of dead boughs lying on the ground, but 

 quickly returning to their favourite haunts among the topmost 

 twigs, with the first show of returning warmth, but as the spring 

 advances, they come much more out upon the prairie, resorting 

 to the clumps of mesquite along the edges of the creeks, and even 

 to the fences of the prairie farms, where they feed, for the most 

 part, upon winged insects, which they seize while in flight, with 

 great expertness, returning again and again to the same perch, 

 like a true flycatcher. They are, at all times, active and restless 

 birds, but especially so at this season, when they are continually 

 on the move, either chasing one another here and there or pur- 

 suing the passing insects. At this time they have mostly broken 

 up into pairs, but during the winter they go in small flocks, in 

 company with kinglets and titmice, which latter they resemble 

 in the manner of their feeding and also in their call-note. Their 

 food at this time consists in great measure of various berries and 

 seeds. 



Dendececa maculosa (Gmel.) Black and Yellow Warhler. — 

 On the 15th May, 1880, I obtained my first and only specimen of 

 this beautiful little bird. It occurred in company with several 

 pairs of Myiodioctes pusillus, in a small patch of weeds along the 

 fence of a farm upon the prairie. I found it exceedingly difficult 

 to obtain, from the persistency with which it kept among the 

 densest growth of the weeds, never for a moment rising above 

 them. It proved to be a female, with the stomach filled with 

 minute insects. 



Dendececa BLACKBUENiiE (Gmel.) Blachhurnian Warhler.— - 

 I obtained a few specimens of this handsome warbler during the
