Blueberries busting out all over

In the first weeks of harvesting, my blueberry crop was disappointing, the berries were small and slow to ripen.  The weather was dry and even though I was watering the shrubs, they just didn't seem to produce.

And then it rained! Last week, we received over two inches of rain over the course of 4 days. 

Suddenly, I have blueberries busting out all over.  The berries started to ripen, turning dark blue and swelling to twice the previous size.  Since the rain, I've picked more than 12 cups of berries and the bushes still have more than half their berries.

Of course, the birds may discover this bounty too . . .
