Flowering big bluestem, a characteristic tallgrass prairie plant. The tallgrass prairie is an ecosystem native to central North America.Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination.
Grassland birds, particularly those of the shortgrass prairie, are one North America's fastest declining groups of animals. Some of birds still inhabiting the shortgrass prairie are the Cassin's sparrow, loggerhead shrike, sandhill crane, scaled quail, Swainson's hawk, burrowing owl, mountain plover and thick-billed longspur. Although the ...
Instead, each species gets one full page. National Geographic, with Alderfer, Paul Hess, and Noah Strycker, also published National Geographic Backyard Guide to the Birds of North America in 2011. A second edition was released in 2019. Like the pocket guide, this guide is 256 pages and outlines the 150 most common yard birds in North America.
Bouteloua dactyloides, commonly known as buffalograss or buffalo grass, is a North American prairie grass native to Canada, Mexico, and the United States. It is a short grass found mainly on the High Plains and is co-dominant with blue grama (B. gracilis) over most of the shortgrass prairie.

Grazing behaviour is a type of feeding strategy within the ecology of a species. Specific grazing strategies include graminivory (eating grasses); coprophagy (producing part-digested pellets which are reingested); pseudoruminant (having a multi-chambered stomach but not chewing the cud); and grazing on plants other than grass, such as on marine ...
