A REAL SYCAMORE WARBLER 
On June 22, 1918, I was standing on the bridge over the Big Barren 
River, three miles north of town, watching for any birds that might ap- 
pear along the river. Near the end of the bridge stands a large syca- 
more tree. Because of the height of the bridge my eyes were on a level 
with the upper limbs of the tree. Suddenly a Sycamore Warbler darted 
in among the leaves and I heard the chatter of young birds still in the 
nest. As the place was inaccessible, either with glasses or by climbing, 
I gave the matter no more thought and had so far forgotten it that 1 
failed to look for the nest when the leaves had fallen. 
On April 19, 1919, I was again standing on the bridge when I hap- 
pened to think of the experience of the year before. While I was tell- 
ing some friends about it, we saw a Sycamore Warbler fly to the same 
place, seize some of the material of the old nest, which was now plainly 
visible, and fly with it to a much lower limb on the opposite side of the 
tree. Here we soon made out a nest in process of construction. 
On April 8, 1920, I visited the place again and a Sycamore Warbler 
was building a nest on another limb, nearly on a level with the nest of 
1918. I often visited the place in 1921, but failed to see either the bird 
or a nest. In all my experience as a bird student these are the only 
nests of this species that I have discovered, even though I have seen the 
bird in small numbers every summer.

NESTING OF THE BELL VIREO 
The Bell Vireo has been known at Red Cloud, Nebraska, for several 
years, but in 1920 we were favored with a study of the nesting bird for 
the first time. About July 10, 1920, one of my friends who is interested 
in birds and has a large garden with many fruit trees, told me of a bird 
that was new to him nesting in his lilac bush ten rods from the house. 
It was about two and one-half feet from the ground and near the outer 
edge on the south side, half covered by overhanging leaves and yet quite 
in sight. Four of us pushed aside the leaves and gazed at the tiny bird 
to our heart’s content. She seemed to think, as her eyes twinkled, “ I can 
see you all right but you cannot see me.” I could not bear to put her 
off the nest for fear of injury or fright, so came again a few days later, 
with the same result. Saturday, July 17, I had to leave for over Sunday 
and feared the eggs would hatch in my absence, which they did, so T 
went with metric rule to take observations on nest and eggs. To my sur- 
prise, as soon as I neared the nest the bird flew off, quite ‘nervous. As 
I wished first to study the line over the eye and a few other points, I
