Feeding Adaptations of Yellowstone and 

 Grand Teton Birds 



Birds are widely distributed in a variety of habitats. Many species, however, 

 are limited to a particular habitat, or even to a niche within that habitat, 

 because they have developed feeding specializations which make them 

 dependent on that habitat or niche. This section features illustrations of 

 feeding adaptations of birds occupying a variety of such niches in Yellow- 

 stone and Grand Teton. 



Environmental Adaptations of Yellowstone 

 and Grand Teton Birds 



In a sense, a national park is a living ecological museum chronicling the 

 interrelationships of living things and the relationships of these living 

 things to their environments. This section explores a few of these rela- 

 tionships, including the adaptations of birds to Yellowstone's hydrothermal 

 regions.
