Tyrannus pipiri is a very well-known bird in North America during the spring and 
summer months, where it is a migratory species. It passes southwards in autumn, and 
returns again in spring. In Mexico and Central America it is probably only present 
during the winter months and during passage. 
In Mexico its range seems strictly confined to the eastern slope of the mountain- 
range until we come to the Isthmus of Tehuantepec, where it crosses to the Pacific and 
is found on both sides of the cordillera of Guatemala and thence southwards to 
Panama. In South America its range is very extensive, as it reaches across the 
Amazons valley to Bolivia 1°. 
Its habits in North America, where it is a very familiar bird, have been very fully 
described’. Its nest resembles those of 7. griseus and T. melancholicus. 'The eggs are 
white, with a roseate tinge and spotted with blotches of purple, brown, and red-brown, 
which are sometimes collected in a ring round the larger end, and sometimes scattered 
over the whole surface of the egg.
