Check the rinds for splits. A ripe pom's skin splits open when rained on or exposed to rapid changes in humidity. Harvest the pomegranate tree when the first fruit splits, even if it the date falls prior to the expected harvest date.
Pyrrhura is the other large genus of conures. These generally greenish conures include the very common green-cheeked conure, as well as the maroon-bellied conure, pearly conure, black-capped conure, painted conure, crimson-bellied conure, and a number of other species.
Sun conures love attention, and like to be handled and cuddled by their owners, but many tend to be cautious and reserved with strangers. One trait I have seen in several companion sun conures (including my own two) is the willingness to lean back into their owner's chest while sitting on the owner's hand or arm.
