Water birds have contour feathers in contact with water that show in their distal one-third adaptations to water repellency, resistance to water penetration and forceful impact with water. These qualities vary according to their intimacy with open wa

In the study reported here we explore a method for extracting information on the identity of fossil bird families from the fossil feather substructure and their possible taxonomic association with extant bird families. Such information can serve as a

We revisit the water penetration and repellency of feathers and these factors' relation to bird behavior and habitat in the light of information that has become available since 1985. We present the physical principles of water penetration and repelle

Dippers (Cinclidae) are the only passerines that find their prey almost exclusively under water. We examined the breast feathers of the five species of dippers for barb diameter and spacing. These results were compared with those measured for other b

1. We examined infrared absorption spectra in contour feathers of 10 species of birds to compare infrared features of the downy and pennaceous regions with the mechanisms of conservation of body heat radiation. 2. At 1700 cm −1 , a sharp increase i
