Mr. Beck says they were probably nesting on Chatham and Abingdon Islands 

 at the time of his visit, but no nests were found. On Duncan Island Beck found 

 two nests from which the young had flown. Tiiey were placed in hollows in tlie 

 limbs of the tree cactus. One, 4 ft. above the ground, was ipiite large, composed of 

 twigs on wiii(^li a layer of tine grass was laid, and lined with an amount of rat hair 

 and feathers of various birds. The second nest was 6 ft. high, and was similarly 

 built, but with a layer of fnr of 4 in. to the entrance of the hole, in the same way 

 as Empidonax in California lines the entrance to its nest. On Februarv 25 the 

 young were in a very worn plumage on Duncan Island.
