ever cowbird eggs or young have been found by us in nests they 

 have been removed. The earliest date on vi^hich an egg has been 

 found is April 26, 1921 and the latest July 22 in a goldfinch's nest. 



Red-winged Blackbird (Agelaius phoenicens phoenicetis). Three 

 nests seen in 1920, the first being in process of construction on May 

 11. (In 1919 we found a nest with three small young on July 23.) 



*Orchard Oriole (Icterus spurius). One nest seen May 23, 

 later found destroyed. Young recently out of the nest were seen 

 June 22, 1920 and June 23, 1922. 



*Baltimore Oriole (Icterus galbula). Four nests seen in 1922, 

 the first on Ma}- 24; June 17 two apparently grov/n young were 

 being fed by a female. 



*Bronzed Crackle (Qiiiscalus quiscula aeiietis). A common 

 summer resident but we have ,kept few notes on the nests found. 

 Birds have been seen gathering material for their nests April 25, 

 1921. On May 13, 1922 a nest was found containing cue egg and 

 five young, one of which was frightened out of the nest 8 days 

 later. (May 24, 1917 the contents of 7 grackle nests were as fel- 

 lows : one nest had one egg, two nests had 4 eggs each, three nests 

 had 4 young each, while the last nest contained 3 dead young.) 



American Goldfinch (Astragalinns Iristis tristis). A nest con- 

 tained on July 22, 1920 two goldfinch and two cowbird eggs. One 

 young bird hatched. July 24, but- died three days later, due appar- 

 ently to neglect by its parents ; the male was never seen while the 

 female was so excedingly timid that, although she had built her 

 nest by the sidewalk, she flew away whenever anyone passed. 



*Engiish Sparrow (Passer domesticus) . An abundant resident. 

 The earliest nest found contained young about a week old on 

 March 20, 1920. April, May and June are the height of the nesting 

 season ; by the middle of July there are few birds still nesting and 

 very few in August. My daughter Constance destroyed in Nor- 

 man in 1922, 480 eggs and young of this pest. 



* Western Lark Sparrow {Choiiidcstes grammaciis striqatus) . 

 Two nests in small pine trees, each containing three eggs, were seen 

 June 16 and 30, 1922 ; both were later found destroyed. 



Field Sparrow (Spisella pusilla). A pair were feeding young 

 in the nest May 15, 1921. 



*Cardinal (Cardinalis cardinalis cardinalis) . Six nests were 

 found in 1920, one each in 1921 and 1922. The earliest was in 

 process of construction April 13, 1921, contained one egg, April 

 21 ; and one young and one egg on May 5. The latest broods seen 

 were one bob-tailed young bird just out of the nest on August 22,
