The scissor-tail is considered a clearing margin species (Lay, 19388) and 
an open country bird (Bent, 1942). Perhaps the removal of woodlands and 
the favorable attitude of mankind toward the species has helped this bird to 
increase its numbers and to expand its range. Climatic and specific adaptation 
factors are probably also involved, as a number of southern species (Painted 
Bunting, Cardinal, Western Kingbird) appear to be expanding their ranges 
northeastward. Perhaps in the near future the Scissor-tailed Flycatcher will 
be found nesting in Illinois.
