definitely looks like a male to me!
yeah, I wouldn't let my flighted senegal and budgie interact with each other though, as once I had my budgie out and my mum took the senegal upstairs to see me. The budgie was on my head and the senegal flew straight AT the budgie and landed on my head, and the budgie flew out of the room. My budgie is very tame and loving and I would HATE to lose him. I just don't want to risk him getting hurt. My senegal, on the other hand, has a somewhat Jekyll and Hyde personality. He will be saying his name and hello in a cute voice and asking for scritches. He may look sweet, but don't let that fool you! Underneath his cuteness, he can be mean too, and he is quite aggressive when he wants to be. He is very nippy, and once he actually made my finger bleed - imagine what he could do to a little budgie?!
Of course, when we were on holiday the budgie and the senegal were in the same room to keep each other company while my brother was looking after them. He apparently had them both out at the same time and no harm was caused, either to the sennie or the budgie. So, if you're going to keep a budgie and sennie together, make sure the budgie at least can still fly away if need be, and they are introduced on neutral territory. NEVER leave them together unsupervised. If the senegal shows any sign of aggression you may need to keep them in separate rooms or let them out at different times.
My budgie likes the senegal. Once he had a budgie playmate, who was another budgie, come round and the other budgie was in his cage while mine was out in the living room. Then mum let the sennie out at the same time. The sennie didn't really pay much attention to the budgie, (although I think he was a bit jealous that this little pipsqueak was intruding on HIS territory i.e the living room, and kept going near his cage, he was a little annoyed at that.)but the budgie WOULD NOT leave Merryn alone! He was up on the curtain rod and my budgie kept on flying up to the senegal, and we kept trying to get it to go in the other direction, but it just kept going towards the sennie! Eventually we had to put Merry away because it was too stressful for me to imagine anything happening to my budgie. It wasn't his fault he was being put away, it was just for the safety of My Moshi. At least Merry didn't really try to attack Moshi when he kept flying towards him. Phew. Good luck!
