*Catbird (Dumctella caroUnensis) . A nest with one egg was 

 found June 6, 1922; on June 21 it contained 3 newly hat:hed young 

 and one egg. One young bird recently out of the nest was seen 

 August 22, 1920. 



*Brown Thrasher (Toxostoma rufum). Nineteen nests were 

 found in 1920, 23 in 1921 and 16 in 1922; of the 58 only one was 

 placed on the ground, the others being bui't at heights varying 

 from 2 to 20 feet. The earliest nests with complete sets of eggs 

 were found as follows: April 25, 1920, 3 eggs; April 15, 1921, 4 

 eggs ; April 20, 1922, 3 eggs. The latest nests contained 2 and 3 

 young on July 7 and 11, 1922. The majority of sets have conri-ted 

 of 3 or 4 eggs ; in 2 cases we have found 5 eggs and once 6 eggs — 

 May 15, 1921. 



Carolina Wren (Thryothorus liidoviclanus ludoviclanus) . A 

 wren was seen building its nest April 6, 1921 ; the nest with one. egg- 

 was later found deserted. 



*Texas Bewick Wren (Thryomanes bewicki cryptus). Four 

 nests has been found, 3 of which are known to have succeeded. 

 These wrens usually build their first nests about the middle of 

 March, bringing off their young in early May. In 1921 a pair 

 built their nest in February but no eggs were laid until the last 

 of March; these hatched April 16; some of the 7 young left April 

 30 and the rest May 1 ; the parents coralled their fami'.y into an 

 old mockingbird's nest for the night of May 2 and into a woodpile 

 May 4; they were still feeding them on May 9. May 15, there 

 were 4 eggs in the same nest. 



■•'P'unibeous Chicadee (Penthestcs caroUnensis anilis). Four 

 nests have been found, one in a wren box on our grounds. A parent 

 was seen building its nest March 30. 1920 and carrying food to 

 young April 17. May 1, May 6 and May 24 are other dates when 

 young have been found in nests. 



*Robin (Planesticus migratorius miqratorius) . Nine nests were 

 found ill 1920, 25 in 1921 and 15 in 1922. The earliest dates were: 

 in 1920 a robin building on March 18, a nest with 2 newly hatched 

 young and one egg found April 18, one young bird out of the nest 

 May 1 ; in 1921 a nest with 4 eggs was found March 23, the 2 

 young leaving April 23, while a young bird from another nest left 

 as early as April 21. In 1921 we found 9 nests with complete sets 

 of eggs in March, but in 1922 the first nest seen was in process of 

 construction on April 8. Late dates were : a nest in process of con- 

 struction June 17, 1920; 2 newly hatched young and one egg on
