and hasten to the disturbed portion of the tree, with the idea that there 

 is some sort of prey to be secured, and woe betide the luckless person or 

 animal upon whom they descend, for the particular brand of formic acid

 in the same tree, and the bird is always very particular to select the same 

 limb for its nest as is occupied by the vicious, trouble-hunting wasps. 

 I do not therefore need to further dwell upon the difficulties of securing 

 nests placed in "Cornusuela" „trees. 



The eggs are creamy-white, with a slightly rosy tinge, speckled and 

 blotched with lilac and umber-brown. Measurements: 23.5X18 and
