To be incredibly blunt with you, Latte is running away from you because you're scaring him.
Budgies aren't a pet bird that are quick and easy to tame. They are not docile birds that will jump on your hand and allow you to pet them.
If you have seen videos or pictures of people online with budgies that are very tame they have worked long and hard on establishing a bond with their bird.
Firstly, while wing clipping is the owners choice and some birds come with clipped wings, it takes away the birds natural ability to fly. If Latte perceives you as dangerous (which he currently does) and he can't fly away, it's going to distress him a lot more.
The fact you are cornering him to pick him up is not helping him to trust you.
You need to start right now by leaving Latte alone.
Feed him, care for him, talk to him, but no more trying to touch and feed him.
When you bring a new budgie home it is advised to cover three sides of the cage to create a safe secure area for them in their cage.
For the first week or two, you do nothing with them. Clean the cage and change the food and water, but besides from that all you do is sit beside the cage and talk to them. you can also sing or read, but you don't out your hands on or inside the cage unless you're cleaning it.
Once they are comfortable (and as your bird is running from you, you should know what his scared body language looks like, so don't move on to step two until his body language looks different. It may be longer than two weeks considering he has learned to run from your hand at the minute) step two is to sit beside the cage the same as before, talking but you put your hand on the cage. Not near the bird, just on the cage. Again do it for at least a week, until they are comfortable with this.
The next step is putting your hand in the cage, just inside the door, not approaching the budgie, just in the cage not making any moves towards the budgie.
You need to work on these steps before you try and progress any further if you want a meaningful bond with Latte.
And start by reading through the following stickies.
These will help you to understand a way to establish a bond with Latte.
The rules here that are established are very important such as no grabbing your budgie.
I feel you would also benefit from reading a lot of our stickies on the basics of budgies pet keeping. Even members who join with experience in caring for budgies learn a lot of new things that help them look after their pet birds.
