Usually when you have 1 parakeet it will bond to the human, and can learn to talk ... buy 2, or introduce a 2nd one into the house, and especially into view in the same room and the once talking parakeet, will stop talking, and the other parakeet will not learn to talk ... I believe this is true for all boids'
Two parakeets in the same cage is a bad idear' ! Two males will fight, and a male will insatiently preen a female so badly that it will result in an eyeball pluck out, or death
I had @ 5 parakeets in my life, all named: Budgie & Wudgie (very original names) ... I taped a mockingbird (who sang for 23 3/4 hours a day/night) on a cassette tape recorder, and they so loved the mockingbird sounds, and got extremely excited. I put a Jelly Belly speckled jelly bean on the cage floor, and the female instinctively tried to hatch it by sitting on it. Parakeets should never be allowed to fly around the house, as mirrors and windows (even when covered with a bedsheet) will break a leg or wing.
I have 2 black cats, brothers, named "Thing 1" and "Thing 2", as they tear up the house, as they have indoor life imprisonment. They sleep together in the sun on the white, black hair covered bedsheet, lick the dog, and occasionally play the rough fighting game called "Kill" ... The spayed female Pomerainian dog Darby, mates with the male neutered kat aka: "Fat Thang", which is oh so wrong on so many different levels, such as cross gender mating, and cross species mating ... but we encourage it and shout: "Go Darby, Go Darby, Go, Go, Go" ! She sometimes gets all four feet off the ground when she digs her claws into the rug for traction, and violently nails the male kat on the rug ... lol ... got to post it on YouTube ! She has never made a R hand turn in her life, and insatiently spins counter-clockwise, we should have named her "Nascar" (only makes L hand turns) :hehe:
The 12 year male chihuahua is so spoiled, that I feed him on the bed, and when I shout: "Lets go up on the bed and have bye byes ride on the bed bisqua' treats", he tears up the stairs and waits for my old bones to struggle up the stairs with his food bowl. When he finally goes, I will go with him on the same day from a massive stroke ... he sleeps in my arms every night, all night long snoring ... I should never have gotten so attached to him. After his meal he stands on my chest, and I pat his belly sides, and he burps in my face ... he is my "Little Boy" !
