This bird winters in Texas and Mexico, and must pass rapidly over the southern States, 
for they are rarely observed in those regions until they reach Pennsylvania. It is first seen 
here at the commencement of May, and leaves us in September, having advanced north as 
far as Nova-Scotia. It is not as common with us as the V. noveboracensis. It is said to 
construct a pendulous nest, in which it deposits 4-5 white eggs spotted with reddish brown. 
Its food in the spring and summer consists of caterpillars, small moths, wasps and wild bees ; 
and in the autumn and winter, of seeds and berries.
