62 Bird - Lore 



Our proposed study of the Warblers, then, may follow somewhat the 

 lines just suggested. Stated more fully, it is requested that each bird on 

 which a report is made be treated as follows: 



Name of the Species. — Give the A. O. U. common and scientific names 

 and any local name in current use. 



Local Status. — Define the bird's manner of occurrence, whether sum- 

 mer resident, transient visitant, etc. ; whether rare, common, or abundant, etc. 



Migration. — Give the time of arrival in the spring from the South, the 

 ■difference, if any, in the arrival of the sexes; the date when the species 

 attains its greatest numbers; if a transient or winter visitant ; the date when 

 last observed. Give the date of departure of summer residents, of arrival 

 and departure of transients and winter residents from the North. (See 

 Bird-Lore, III, 1901, p. 27.) 



Song. — Describe call-notes and song, and any especial significance (e.g., 

 in courtship or as a means of communication) which may in your opinion 

 be attributed to them; any sexual dif!ference in call-notes; whether female 

 is heard to sing; duration of song period; giving earliest and latest dates 

 when species is heard to sing; has it a second or fall song period; give 

 •station usually chosen for delivery of song, — ground, tree, etc. ; is there a 

 flight song? any seasonal variation in song? (See BiRD-LoRE, III, p. 28; 

 V, p. 56.) 



Courtship. — Under this head note any obvious attempt by the male to 

 -win the attention of the female through display of plumage or of vocal 

 powers. 



Haunts. — Describe the character of the locality in which the species 

 is found most commonly. Is there any seasonal variation in haunts? 



The Nesting Site. — Give exact location of site or sites in which nests 

 have been seen. Does either sex select the site? Is the same site ever used 

 again for a second brood or in a subsequent year? (See BiRD-LoRE, V, 



P- 57-) 



The Nest. — Describe materials and shape; is it built by female or male, 

 or both? Give time occupied in construction; date when finished. 



The Eggs. — How long after the nest is completed is the first egg laid; 

 when is the set completed? How many eggs does it contain? When does 

 incubation begin; how long does it continue? Is it performed by the 

 iemale alone? If by both sexes, is there any regularity in their daily periods 

 of sitting? Is the sitting bird ever fed while on the nest? 



The Young. — What is the appearance of the young at birth? If blind, 

 when do the eyes open? How long after hatching before the 3'oung birds 

 are fed? How are they fed? What is the nature of their food? Does the 

 ■food or manner of feeding change as the birds grow older? About how often 

 are the young birds fed at a given age? How is the nest kept in a sanitary 

 condition? At what age do the young have the nest; do they ever return
