Feather quill interior by SEM. As a fracture shows,the interior consists of a pithy material that contains air cells to make the quill light yet strong. This feather is from a common grackle (Quiscalus quiscula),now the most abundant type of breeding bird in North America and considered a significant pest in many areas because it feeds on agricultural grains and seeds,especially corn. Enhanced SEM. Image width: 174 micrometers. Bar: 20 micrometers. Magnification: 575x if the image is printed 10 cm wide | |
