It's a big step, and all it takes is about 10 seconds. Zap! You're pregnant! now start decorating the baby's room, shopping for cute little onesies and diapers and really expensive diaper bags that come in really cool colours and patterns now with all sorts of pockets and pouches for baby necessities while travelling to your mom's for an hour to escape the fact that this is a REALLY BIG STEP you took, and it lasts a lifetime!
But imagine being a bird!! And doing it every year. And every year the kids leave - yay! so you can get busy and do it again, and again. That is what you do, if you're a bird. You take a leap of faith one day, and plop out of the nest. Then you fly around free as a bird for a short shiny spell. Then some brightly coloured gadabout catches your eye, and before you can flip him the bird, there you are - sitting on a bunch of eggs! Feathering your nest and waiting for the "pick, pick, pick " to start so you can start flying hither and yon catching bugs like a crazed bird brain, burping them up into outstretched beaks leading to huge empty stomachs, and then off again, and again, and again! Then one day, the fluff balls take a leap of faith, and you fly 2000 miles south, and do it again, and again.
The Green Herons' "Kronk!" is about as rude a call a bird can have- kind of like saying "Git outtta my way! Here I come with food. Open yer mouth right now!" And I'm guessing it's a good thing the babies are so gosh durn cute, or Tired Old Bird (Mom for short) probably wouldn't even bother feeding them!
Just look at those little eyes...what's not to love!?
