Bye, bye blackbirds

Because there's no such thing as a freeloader forever lunch;

The dairy farms of the Central Valley have proven good nesting sites for California's tricolored blackbird. Grains grown to feed the cows resemble the lost tules and cattails that the picturesque songbirds once called home, providing the flocks new sanctuary to raise their young.

That is, until harvest time.

Scientists say the blades that pluck the feed crops are also mowing down thousands of baby blackbirds and eggs - one reason the bird is in rapid decline. 

The dairy farms giveth...and then taketh. Stupid birds.
