She descended involuntarily to the earth. A shout of joy arose from every member 
to celebrate the end of a perilous but successful day. The eggs were well advanced 
in incubation; the average measurement was 2.03 inches. The reader’s attention 
is called to the similarity of this nest to that described by Mr. Peabody in the 
November number of^the Condor, 1907.

NESTING NOTES ON THE LUCY WARBLER 
By M. FRENCH GILMAN 
T HIS trim little gray warbler with chestnut rump and crown patch ( Vennivora 
luciae ), might properly be termed the Mesquite Warbler, as his favorite shelter, 
home and playground seem to be furnisht largely by the mesquite, and 
insects about the bloom of the tree loom large on his daily menu. It is very 
numerous about the mesquite groves and other growth along the Gila river bottom 
and seems to be the only warbler nesting in this locality. 
The few notes here presented were made during the seasons of 1908 and 1909 
at points along the Gila river in Arizona. Observations were made at Blackwater, 
1362 feet elevation; Sacaton, 1275 feet; and Agua Caliente, 380 feet elevation. At 
the latter point, about 100 miles down the Gila river from Sacaton, I spent two 
weeks last April and found the Warblers more plentiful than at the other places 
mentioned.
