Wildlife and Other Sightings: Golden Digger Wasps & Feathers

Golden Digger Wasp
Keep an eye out for feathers on the trail as the birds of Yosemite are replacing their flight feathers this time of year. This process is called molting and it allows the birds to replace damaged or worn feathers. Although birds molt every year, not all feathers are replaced at once and some species take several years to replace their full set. This pattern of old and new feathers is a handy way for researchers to estimate the age of a bird.

The indigenous people of Yosemite Valley have used fire as a tool for thousands of years. Fire was used to encourage the growth of plants used for basket making and to promote the growth of the black oak--a sun loving species--and a staple food source for American Indians from this region.
