Hahaha! It's that time, eh Katie? At just about 3 years old Jasper's actually right on target. It was more or less the same for Maya and Jolly.
Some ekkies handle the transition more smoothly than others. I've been fortunate so far. Maya had one bad day. One. Last year. It's the one time she ever drew blood from me. And it was a doozy. Still have the telltale crescent-shaped scar to mark the occasion. Lol! As for Jolly, though I'm his favorite person it turns out Aida (my wife) is the more frequent object of his desires. (When he tries to come my way with his Romeo routine, I just remind the little Lothario that I literally just watched him put the moves on my wife 5 minutes earlier! Hahaha!) Anyhow, in his case he makes his moves and then merely gives one loud, exasperated scream when his advances are turned down. To this day, though, Aida still laughs whenever he whispers, "Gimme kissssssss!" The innocence of the phrase is forever lost with her. Lol!
As Steven mentioned, you'll have to pay closer attention to his body language and then put him down to head things off before he starts getting too amorous. Aside from the obvious signs to look out for, I've noticed 2 signs in Jolly that may prove helpful for you. For one, his beak flushes and the candy corn colors get more pronounced and striking. And second, his beak gets really hot. The minute we see either of those signs, he goes straight to the tree stand to cool off. Lol!
