In the last couple of weeks, Scooter suddenly seems to be startled by/afraid of objects he was never bothered by before. The scale I weigh him on being one example, and the sink he normally bathes in being another. If I lift or move any object around him, he gets upset and either alarm calls or flies off (he is clipped but can make it from my desk to the hallway without much trouble). Prior to this, the only thing that ever really set him off was lifting and moving the vacuum cleaner that lives next to his cage.
He'll be two in a couple of days. IS it fairly common for a maturing bird to suddenly become more reactive, even in a familiar environment? Are there nutritional deficiencies that can cause nervousness? (Magnesium deficiency in horses can exacerbate spookiness).
He will be due for a vet checkup soon, so I'll probably do that quite soon. He seems quite healthy, but I've always thought of him as fearless and happy-go-lucky, so it bugs me to see him suddenly shy and spooky.
