The peregrine falcon eggs at San Jose City Hall hatched last night!  Right now on the webcam Clara (mommy) is busy feeding the chicks.  Less than a day old and already ravenous (bad pun).

Birth of peregrine falcons makes an auspicious Earth day!  They were on the brink of extinction 30 years ago due to the extensive use of DDT as insecticide.  Unfortunately DDT also caused peregrine falcon egg shells to become thin and brittle, thus easily killing unhatched chicks.  Their recovery is a symbol of conservation and environmentalism.  Let's keep it up for the future!

ETA: Looks like Clara is done feeding and is now keeping the chicks warm while they take a nap.
