So the general idea is that many sennie's are one person birds, but how about other birds? Do they get jealous or aggressive when you give attention to your other birds?
Your description sounds exactly like my Silas. He's now 3, and the best bird I've ever owned, hands down.The attributes listed in this thread are the experiences of each individual and your experiences may differ with your individual bird.
The good - Paris is very affectionate and loyal. I can do almost anything to her without complaint. She is happiest when she can be with me getting attention. She is an excellent eater and will eat almost any food I give her. She is very playful and really plays with her toys. She is a great acrobat and is very entertaining. She loves to bathe too. She is very quiet. My most quiet bird in fact. We communicate with soft whistles and clicks, which is adorable. She is a one person bird but I believe this makes our bond stronger.
The bad - Paris is a one person bird. She is scared of everyone else, despite my efforts to socialize her as a baby. She freaks out if anyone else approaches her. If they persist despite her warnings (fluffed head and clicking beak) she will bite out of fear. I think due to their nature of being one person birds it can take a lot of time and effort to earn their trust. Patience is very important when it comes to creating a bond with a Sennie, but in my experience it is an incredibly strong bond.
The ugly - Paris is extremely jealous and aggressive towards other pets. She knows no fear and will go after my 40 pound dog and Alex my Macaw if given the chance. And she can be very persistent, especially with the dog. I just avoid them being in the same room. I have no doubts that she would seriously injure or kill one of the smaller birds if given the opportunity. She is also very protective of her mommy and will attack anyone who dares to touch me while she is on me.
This is just my experience, and Paris is only one year old so a lot may change as she matures. I hope others will add their insight regarding the good, bad, and ugly about Senegals.
I'm pretty new to the Avenue and parrots in general so I suppose there'll be huge differences between the two, but how would you compare a Senegal to a Cockatoo? I know there are several different species of cockatoo and only one Senegal species but from what I've read, they both seem to bond very tightly with their owners and tend to be one-person birds. Apparently Sennies are usually waaaay quieter but what else is there?
