TYRANNID.E — THE TYllANT FLYCATCHERS — MYIARCHUS. 3^5 



sycuiiiore-tree, tlieir notes being loud and much more musical than those of 

 the other sj)ecies, Avith considerable variety tor a bird of this family. 

 During the middle of the day they are ratlier quiet, and sit much of the 

 time on tlieir percli, occasionally catching an insect that comes very near, 

 but I think their feeding is done mostly in the very early morning. 



I fomid them breeding at San Diego as early as March 2Sth, as well as 

 subsequently. The nest is much larger and more firmly built than that of 

 the others, being 5.50 X 2.50 inches externally, and 3.00 across the cavity, 

 the eggs 0.96 X 0.70 inch, white with large scattered reddish-brown and 

 undjer blotches. I found some of these birds in Santa Clara Valley in 

 May, 1804, which were smaller and greener on the back than those from 

 tlie south. 



They winter in small nundjers at Santa Cruz, lat. 37°, together with Trog- 

 ludi/ics rarliitaiini and Iliri/iulo hkolor, indicating a much milder climate 

 than anywhere else in the State.
