Katy,
Improved kieffer will be ripe soon. The pears in your picture appear to be close so I would keep a close eye on them and tilt the stem up daily. When they break off in your hand when you tilt the stem up they are ready to pick but will need brought inside then to turn yellow before they can be eaten. See this thread that shows improved kieffer ripening in August and your climate is warmer Here comes the 2016 apple and Pear harvest!. A true kieffer ripens as mentioned in September in our climate typically.
