"To the Tree Trappers; most of the Warblers belong to this, while some have joined the Sky Sweepers, and a few the Ground Gleaners and Seed Sowers."
"Look!" said Nat. "He has spent a long time on one twig and he doesn't seem to have cleaned off all the insects yet; he must have pretty good eyes."
"Yes, and more than that," said the Doctor, "his eyes magnify much more than ours do, so that all objects appear far larger to a bird than they do to us, and they can see insects that we never notice."
"I wonder if that little Warbler thinks spiders are crabs and flies chickens," said Dodo, so soberly that all the others laughed heartily.
The Black-and-white Warbler
Length five inches.
Upper parts striped everywhere with black and white.
Under parts white in the middle, with many black stripes on the sides.
Has a weak and wheezy voice.
From its habit of scrambling about tree-trunks and branches, it may be mistaken for a real Creeper, or a Nuthatch, or even a little Woodpecker.
