Tree Swallow. A single bird seen from April 5th to 

 13th. A flock of seven arrived on April 14th. A bird box was 

 placed on the verandah of one of the cottages and on May 4th 

 a pair started nest building. The work was carried on in a 

 desultory fashion and the nest was not completed until May 

 21st. It was a loose bundle of hay with a deep cavity in one 

 corner, well lined with white hen feathers. The first egg was 

 laid on May 2 5th and one was laid daily until May 30th. The 

 nest and eggs were taken and the birds began immediately to 

 build another. The second nest was identical in appearance 

 with the first and was completed on June 7th. By June 14th 

 the complement of eggs was laid; June 26th, four eggs were 

 hatched and the remaining two on the following day. July 8th, 

 the young were almost full fledged and had left the feather- 

 lined cavity and were huddled together in a corner of the box. 

 The nest was as clean as before the eggs were laid.
