Bird Feather Diagram
The diagram follows one presented by xu and guo 2009 modified with the findings of foth 2011. A perched bird shows a very different and less helpful view of its wing than a bird in flight.
Use a hand lens to look at a contour feather and a down feather.
Bird feather diagram. The same wing feathers can be seen on perched birds though most of the structural wing parts that are useful for identification are hidden. For example the interlocking velcro like structure on many bird feathers creates the smooth flexible and resilient surface that supports flight and sheds water. Compare and contrast the birds using the venn diagrams below.
See diagram above if barbs separate and the vane splits the bird can repair it by preening. All parts of birds are protected except game birds. They should not be gathered from the wild.
Bird and feather features materials pictures of birds from magazines or provided in this packet. Bird features handout for each student. Running the barbs through its bill reconnects the hooks like a zipper.
Understanding feather anatomy at the microscopic level provides insight into how feathers function. Feather diagram made. Name activity sheet 1.
On the contour feather label the following. Amazing birds student manual name. Feathers contour and down from a poultry farm or wards biology catalog.
As feathers grow they mature into highly branched structures. In most birds the body is divided into areas that contain feather tracts pterylae and areas that do not apteriaethe location and the number of tracts varies between species. The following simplified diagram of dinosaur relationships follows these results and shows the likely distribution of plumaceous downy and pennaceous vaned feathers among dinosaurs and prehistoric birds.
Birds have six different feather types that vary in shape structure and function. Make a scientific drawing of each. By originating from tracts rather than being randomly distributed feathers can smoothly overlap and conform to the natural contours of the body.
