Excerpt from The Photographic Analysis of a Feather

For the benefit of the uninitiated it may be well to recapitulate some of the details connected with feathers in so far as concerns the present work. The large wing feathers are called Primary and Secondary. Covering the base of both are layers of small feathers called Coverts. The general body covering feathers are called Contour. The last type dealt with is the Filoplumes, which are hairrlike filaments close to the skin.

Excerpt from The Photographic Analysis of a Feather

At the suggestion of my cousin, H. S. Gladstone, a keen Ornithologist, I took up the examination of Feather Construction. He pointed out to me that up to date the illustrations in ornithological works were hand drawings and that a set of photographs would be of some value.

My cousin very kindly obtained for me from the Zoological Gardens, Regents Park, a collection of feathers ranging from the Golden Eagle to the diminutive Parrakeet. In addition to these the shooting season provided feathers of British Game Birds, so I was able to examine specimens of practically all the orders of British Birds. After a lengthy study with the microscope the conclusion arrived at was that the construction of a feather is the same, whether it belongs to a Golden Eagle or a Sparrow. It was clear therefore that all that was necessary was to record typical species.

For the benefit of the uninitiated it may be well to recapitulate some of the details connected with feathers in so far as concerns the present work. The large wing feathers are called Primary and Secondary. Covering the base of both are layers of small feathers called Coverts. The general body covering feathers are called Contour. The last type dealt with is the Filoplumes, which are hair-like filaments close to the skin.
