Ww: WARBLER is during the migrations a more or less common bird 
throughout the country. In the last days of April it reaches south-eastern 
Texas from its winter-quarters, which are usually the mountainous regions of Mexico 
and Central America. Where the trees are adorned with many species of epiphytal 
orchids, this small Warbler finds a congenial winter home. Many of these wonderful 
beauties are in full flower early in spring, especially Odontoglossum citrosmum, whose 
pendulous spikes, a yard long, adorned with innumerable white and lilac flowers, perfume 
the air with their delightful fragrance. The stoutest branches of the oaks are literally 
loaded with these orchids. Lelia anceps, L. albida, L. acuminata, and many other 
species of the wonderful orchid family are in full fower and fragrance in winter, when 
many of our beautiful Warblers hunt among them for their insect prey. 
In south-western Missouri it appears in the first week of Mey, and in central 
Wisconsin we may observe many of them about May 20. 
Its breeding range must be looked for in the Arctic regions, near the Yukon in 
Alaska, etc., in Labrador, in Maine, in the mountains of New Hampshire and Vermont, 
and in the Rocky Mountains. Prof. J. A. Allen gives the following interesting account 
of this bird, as it appears in Colorado: 
“The Black-capped Warbler is a common inhabitant of the subalpine and alpine 
distri@ts in -the Colorado Mountains, breeding from about 8,000 feet up to timber- 
line. In the dwarfed willows and other low shrubs that grow for some distance ahove 
the limit of trees, we found it by far the most numerous of all the insectivorous birds. 
It’ was here more plentiful even than at lower points, and may hence be regarded 
as an eminently alpine species. Although evidently breeding, we failed to discover its 
nest. It manifests great anxiety when its chosen haunts are invaded, and during
