Tlie nest is always placed in the lower branches of a 

 coronillo tree facing the east, except when built under a 

 veianda or summer-house near habitations. 



I have the following note from Miss Runnacles : — 



" One nest that was suspended from a wire under the 

 eaves of the house was commenced in the early part of 

 November, and when half finished the birds deserted it. 

 After a month the pair returned and nearly completed the nest, 

 when it was again left, and, finally, at the end of December 

 they once more returned, completed the building, laid eggs, 

 and brought off the young. They are very fond of human 

 habitations and are often seen hovering round the windows 

 catching insects, and if flowers are in the room they will 

 come in through the windows and doors." 



The nest is sometimes suspended, sometimes attached to 

 the branch ; it is deep, cup-shaped, and composed of lichen 

 and cobwebs lined with thistle-down, while two eggs are the 

 full clutch. 



Eight eggs brought home were taken at Ajo between 

 November 12th and January ]8th. They measure: axis 

 0-5 to 0-58 inch, diam. 0-33 to 0-35.
