Ruby-crowned Kinglet 511 
at 11,000 on July 25th in San Juan co., and concluded that it must 
breed at about this elevation, while Aiken recently obtained a female, 
now in the Colorado College Museum, at Clyde, in Teller co., 9,400 
feet, on January 12th, proving that a few birds at least winter in the 
State. One taken by Gale in August in Boulder co. is now in Mr. 
Felger’s collection, another was recently shot in the same district by 
Betts on February 6th, out of a flock of eight. Finally, Morrison states 
that he observed it three times in La Plata co. 
Habits.—The Golden-crowned Kinglet resembles its 
cousin the Ruby-crowned in its habits, but has rather 
a different call-note—a fine high “ Ti, ti,” only audible 
to practised ears. The nest, generally pensile, composed 
of green mosses, lined with fine bark strips, rootlets and 
feathers, is placed in coniferous trees from six to sixty 
feet up. The eggs, nine or ten, are creamy-white, 
blotched and speckled with pale wood-brown, and rarely 
faint lavender; they measure ‘55 x ‘44 (Brewster, 
“ Auk,” V., p. 337). 
Ruby-crowned Kinglet. Regulus calendula.
