making of this film, will show the result of two seasons’ work in Yellow- 
stone, our oldest National Park, dedicated in 1872 “For the benefit and 
enjoyment of the people.” The wildlife of the area is shown against a 
background of spectacular mountain scenery, fascinating geysers, and 
brilliant fiowers, and the artistic photography of Mr. and Mrs. Maslowski 
will make a fitting close to our course of lectures. 
All films for these subjects will be in full natural color and will be 
shown as usual at eight o’clock on the several evenings at the Chicago 
Academy of Sciences, Clark Street at Ogden Avenue. Members of the 
Society, their families and friends, and any who are interested in the 
protection of our native wildlife are most cordially invited to be present 
at any and all of these lectures.

Have You an Answer 
THOSE WHO MAKE a study of bird behavior or bird psychology may be able 
to answer the questions propounded by Mrs. Martha Miller Stofer, a 
member of the Benjamin T. Gault Bird Club of Glen Ellyn, in the following 
comments upon her experiences in bird feeding: 
“As I watch our feeding station with its many regular guests, I muse 
with the thought, Why do we have certain regular birds feeding one year 
and not another? 
“T know that we have stragglers that are considered special guests, and 
since we started our feeding station in 1932 our special guests have been 
the Carolina wren, red-bellied woodpecker, red-headed woodpecker, flicker 
and song sparrow, these staying all winter; then we have had others staying 
for short periods of time. 
“This winter we have become especially interested in the behavior of 
the tufted titmouse. We have always considered him a regular guest as 
we have had them with us for six years straight, then a period of three 
years absence, and now we again have a pair. Literally he is truly a 
regular guest, for if he selects your station as his station every one is 
busy; he appears at the table more often over a period of time than any 
other bird. 
“Back in the summer of 1934, when I was very new at birding, I dis- 
covered what I thought to be a pair of tufted titmice building a nest in the 
hollow top of a clothesline pole in a neighbor’s yard. I called on Mr. 
Benjamin T. Gault (whom you all know) to come to my assistance. I knew 
he doubted me, but he consented to sit one whole afternoon in my back yard 
before they appeared at the nest again, and he identified them as such. He 
believed it to be the first nesting record for DuPage County, and in his 
genuine way complimented me on the observation. Being very much en- 
couraged, I made notes in my book ‘What Bird Is That’ (the only bird book 
I possessed at the time) and I have since added dates and data to this 
which I now hope might be interesting to someone who is keeping yearly 
records. 
“IT was not able to follow up the nesting of that summer, but the pair
