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.

Natural fires in Yosemite are often no more than a single burning snag (standing dead tree) or a slow moving, low intensity fire that cleans underbrush from the forest floor. These fires prevent unwanted fires by removing accumulating forest debris that can fuel a larger fire in hot, dry conditions.
