Force

Why does a truck full of birds at rest weigh the same as the same truck with the birds in flight?  The birds are weightless in the air, right?  That’s why they don’t go splat.  Flying birds should make the truck weigh less.

Turns out it’s more complicated than that. 

Chickadees

A flock of what appeared to be black-capped chickadees descended on the church property this week.  (Forgive me, Mom, if I’m ornithologically incorrect here.)  Tiny little things, just hopping all over the place looking for seeds.  Peck.  Hop.  Peck.  Hop.  Peck.
