for some little height from the ground. It is made of twigs, 
with a foundation of mud and clay, and is nearly always 
covered over with a kind of dome, the entrance being by a 
hole in the side. This hole is generally guarded by thorny 
sticks, so that even when one has climbed up to it, it is by 
no means easy to get one’s hand inside. The nest is used 
year after year, being carefully repaired early in every 
spring, and usually contains from six to eight eggs, which 
are pale bluish-white in colour, spotted with grey and 
olive-brown.
