Central America. 
The Titlark is a common spring- and fall migrant, arriving here usu- 
ally about the first week in October, and remaining generally until about 
the middle of November ; occasionally small parties of these, shy queru- 
lous-voiced birds are seen as winter residents in our southern counties. 
When migrating northward this species again makes its appearance 
about the middle of April, and oftentimes a few scattered individuals 
are found about plowed grounds or along pools and other wet places in 
fields, meadows, etc., as late as the middle of May. Titlarks, during 
their stay with us, are usually seen in flocks of from ten to twenty on 
forty each, but at times larger flocks (one hundred or two hundred each) 
may be observed. These birds sometimes alight on fences or on the 
dead limbs of trees, but usually they are seen, when not flying, on the 
ground, as Mr. Bidgway writes * they move “ with a graceful gliding walk, 
tilting the body and wagging the tail at each step, much in the manner 
of a Seiurus. It is very restless, the flocks seldom remaining long at one 
place, but soon taking wing, they flit to another spot, or in graceful 
sweeps pass and repass over a particular place before alighting.” In 
this region I have noticed that the Titlarks are nearly always to be found 
frequenting plowed fields, where they collect insects, and their larvae as 
well as small seeds on which they feed.
