You thought eggs were hard!
It gets even harder after they hatch! This is how they looked on Wednesday. These demanding beaks have the parents flying in and out delivering food as fast as they can.
There are three Kildeer just in back of the paddock, each defending it's nest of pebbles and eggs on the ground. I haven't seen the nests, but every time I look there is frantic cheeping and running around to divert my attention from the nest locations. This season is for birds what the Christmas season is for retail sales.
