Reseña del libro "Wing-Tips - the Identification of Birds in Flight (en Inglés)"
This antique text contains a detailed yet accessible treatise on bird flight and how to identify birds based on how they fly. This book is intended principally for the ordinary bird-lovers who, without being ornithologists, are interested in bird life and look with wonder at birds in flight wishing to know more of how they fly and why their flight differs so much from species to species. The perfect handbook for amateur bird-watchers, 'Wing-Tips' constitutes a great addition to any collection of ornithological literature. The chapters contained herein include: 'The Skeleton', 'The Sternum or Breastbone', 'The Bones of the Wings', 'Muscles', 'The Feathered Wing', 'Tails', 'Flight', 'Different Shapes of Wing', 'Rising', 'Landing', 'Gliding', 'Hovering Flight', 'Birds of Prey', 'The Owls', 'Ducks', 'Waders', 'Migration and Wing Formation', 'Snipe', 'Crows', and 'Pelicans'. This text was originally published in 1947 and is proudly republished now complete with a new introduction on ornithology.
