woodpecker hollowing out a dead tree

How do they do that.  The question nobody asks - how a woodpecker hollows a tree?  I answer.

 Hummingbirds are birds that comprise the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5--13 cm (3--5 in) range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm Bee Hummingbird.

 They can hover in mid-air by rapidly flapping their wings 12--80 times per second (depending on the species). They are also the only group of birds able to fly backwards.

 These are Christina Lake, BC Hummingbirds. These little birds are going to be facing eminent danger. British Columbia mountains are rapidly being stripped of forests for raw log exports to the USA & China. In addition to this, there is colossal devastation of our forests from the Pine Tree Beetles kill. Millions and millions of acres of pines trees, entire mountains - dead trees. These forests are the feeding grounds of these amazing little travelers. I so fear for their future.
