Their wingspans are generally around seven and a half inches; and they weigh between 3 – 5.8 oz (84 – 165 grams) and their and their expected lifespan ranges from 25 to 30 years.While Blue Crowns have a reputation for being one of the more quiet species, of conures, they do have the ability to scream and screech, and can be quite vocal upon waking and before bedtime.
