Description:

On our way from one eco-lodge to another we stopped in San Jose to get some groceries and supplies. I stayed with the car to guard our camera gear while Dave went in the store. iNatted a few birds flying over the parking lot. Blue-and-white Swallows may be told from things like Tree Swallow or Violet-green from the black undertail coverts. This swallow species is very common here.
