Be careful with the Senegal around Lilo. They generally don't seem to like other birds and have quite an attitude. Mine will sometimes try to attack the blue crowns. Both of them have learned to be very cautious about him and will get the heck out of Dodge if he is even close. He will also fly straight at them occasionally. For all their size, they have very powerful beaks and could possibly do real injury to Lilo.
But other than their antisocial behavior with other critters, they can be great little birds. LOTS of attitude and more to spare. My Sidney is certainly the most challenging bird that I've ever had. He is almost constantly wanting to explore and get into something he shouldn't be in.
Hope he turns out to be a great bird, though. Good luck!
