Recently, my one of my budgies have passed away. I haven't seen any health or activity changes in my other bird, Choco. I still don't know if he understands what happened. Here are some of the questions I have:
1) If Choco didn't know and finds out, will he act any different? If so, should I be concerned?
2) They only knew each other for a year and a half, should I get a new partner?
3) Since he may be lonely, should I spend time with him or leave him alone for a while.
Choco is also a quite timid bird, so this concerns me. Thanks for reading!
Since Choco hasn't changed his activity there is really nothing for you to be concerned about.
The best thing for you to do is spend time with Choco.
I would not rush out and get another budgie.
Take the time to allow Choco to get used to being a solo bird. Many budgies are very happy as "only" birds as long as their owner spends time with them on a regular and consistent basis.
As Choco is very timid, you definitely want to consider the fact that if you do get another budgie in the future, you may well have to house it separately on a permanent basis if it bullies Choco.
There are many things to take into consideration before getting another bird.
1. If you decide to get another budgie in the future, please be sure to observe quarantine for the new budgie.
Quarantine means housing the new bird in a different cage in a different room than the current bird (as far away from the room the current bird is in as possible) for a period of 35-45 days.
Budgies mask symptoms when they are ill. Symptoms may not show up for over two weeks.
Often you will not even realize your bird is not well. Many budgie illnesses are airborne which is why you need to quarantine your new bird in a completely different room.
It is also a good idea to always take a new budgie in to see an Avian Vet for a "well-birdie" check-up. This allows you to develop a good relationship with the vet and the vet can establish a baseline for your bird in case of any future illnesses or injuries.
