Spring Bird Hikes 
APRIL AND MAaAy—green grass underfoot—blue skies overhead—balmy 
breezes all about—and birds, on the ground, in the trees, on the lake, and 
flying through the open spaces. It’s time to take those regular trips to test 
your knowledge of birds and add to it. If you live on the north side of 
Chicago, won’t you join the Audubon group led by Miss Doris A. Plapp 
that meets at the bird sanctuary, just back of the totem pole at the east 
end of Addison Street, at 7:30 A.M. every Saturday from April 4 to May 30. 
If you like to get out earlier, there’s no law against it; if that time is too 
soon you’ll find us in the neighborhood of the sanctuary and Belmont Harbor 
for about an hour. From there we expect to hike north along the lake to 
Montrose Harbor, and then on to the region of Foster Avenue, where there 
are some beautifully neglected fields, bushes and thornapple trees that make 
up good bird country. This will be the fourth annual series of these happy 
trips. We’re looking forward to some more good times. We’ll be looking 
for you. If you don’t like to walk so far, or urgent duties call you away, 
you'll be excused anywhere along the line. 
Remember: Lincoln Park Bird Sanctuary, 
East end of Addison Street, east of the totem pole, 
7:30 A.M., April 4 to May 380, inclusive. 
If you live somewhere else in Illinois and have a local bird group, 
won’t you sponsor a similar series of hikes? Advertise them in the schools 
and your local paper. You will find there are many people just looking for 
such an opportunity to learn to know birds. When you have a particularly 
good trip, write up an account of it, take a picture of the crowd, and send 
it all in to the office of the Illinois Audubon Society, 2001 North Clark 
Street, Chicago, for publication in the next issue of the Bulletin. Articles 
fur the June issue should be in by May 10, sooner if possible.

Bluebird Houses 
SEVERAL REPORTS have been received regarding results obtained from the 
placing of the bluebird nesting boxes distributed by the Illinois Audubon 
Society early last year. We are naturally quite pleased that so far they 
have been successful in attracting a fair proportion of bluebird occupants. 
From the experimental farm of the Chicago Tribune Bob Becker 
writes: ‘We feel that the houses were highly successful last summer. 
Eleven of the 20 houses were occupied by bluebirds. We did have some 
trouble with wrens, several pairs taking over the bluebird houses. We have 
kept a record of the sites where all of the houses were put up last year and 
will put the boxes up again this spring in the locations where they were 
occupied by bluebirds.” 
Mr. Allan Gonnerman says, ‘‘One in Palatine has bluebirds in it, while 
the one at Palos Park did not attract them. I made a house about one inch 
larger all around and they had a choice of both houses. The one with the 
nameplate was chosen, so you win again.”
