 eggs warm. The eggs are just like those of the last species, 

 white, speckled with reddish-brown, these being the only 

 ones of our swallows that lay other than pure white eggs.

 observers. As the last one has a square tail with no white 

 spots, and a buff-colored rump, while the present species 

 always has white spots on a forked tail, it should be easy to 

 identify them whenever or wherever they are seen.
