Bird Watchers Wanted — II 
By JAMES H. ZIMMERMAN 
A NATIONWIDE STuDY of bird migration is being made by a number of bird 
societies in an attempt to discover how rapidly various species migrate, 
whether their travels follow definite patterns, what influence weather has 
on the appearance of certain species on certain dates, and so on. The Wis- 
consin Society for Ornithology is acting as a clearing-house for data 
gathered in Middle-Western states. An earlier appeal to the Illinois Audu- 
bon Society resulted in a favorable response from a number of your mem- 
bers. [See the March, 1952 issue of the Audubon Bulletin, No. 86, p. 15}. 
We are appealing again for volunteers to send their data to us or for one 
person to act as a cooperator who will collect all Illinois reports and for- 
ward them to us at Madison. This person is welcome to use the data for 
his own purposes first, as to prepare articles for publication in the Illinois 
Bulletin or other journals. Records for the Illinois area should also be sent 
to Mr. Val Nolan Jr., 806 S. Henderson St., Bloomington, Indiana. Nation- 
al data are eventually assembled by Mr. Chandler S. Robbins, Patuxent Re- 
search Refuge, Laurel, Maryland. 
Intensive studies are being made along the following lines: (1) White- 
throated Sparrow. We are following this species north and south for five 
years. Spring and fall counts should be taken daily over a fixed route or 
area. Records are needed for: (a) last date observed in 1952; (b) first 
arrival date in spring; (c) noticeable increases or decreases in numbers; 
(d) first and last dates observed in fall. Bird banders’ records of sexes, 
juveniles, returns, etc. are especially wanted. 
(2). Geese. We want to know when and where main flights occur. Report: 
(a) all flocks heard and seen, giving numbers, species if known, direction, 
relative height, date and hour; (b) records of resting and feeding flocks, 
including dates of appearance and disappearance. 
(3). Night Migrations. Lunar observations will be made again on Septem- 
ber 1 to 5, October 1 to 5 and October 30 to November 5. The reports 
should be combined with daytime observations of arrivals or departures, 
particularly migration waves, and records of local weather during the 
dates involved. [See the December, 1952 issue of the Bulletin, pp. 8-9—Ed.] 
The over-all study has now been expanded to include the 28 species listed 
below. The first 14 cover some species which might be winter residents 
in Illinois; if any doubt arises whether a first arrival is actually a win- 
tering bird, the arrival date should be given just the same. 
Canada Goose Eastern Phoebe American Goldfinch 
Marsh Hawk Common Crow 
Killdeer House Wren Sa Oa ree 
Mourning Dove Red-winged Blackbird Chipping Sparrow 
Yellow-shafted Flicker Myrtle Warbler White-throated Sparrow 
The second 14 species are migrants for which first spring dates only are 
desired. Any additional notes on White-throated Sparrows or geese are 
also welcome.
