Well there's really no such thing a start or beginner bird... its more about what species of bird is suited to you. What really attracts you to getting a bird?
What's your lifestyle like?- Do you work? (if so what hours)
A cockatiel is a really nice bird if you're new to owning birds, I wouldn't say it was a starter bird but its definitely a good place to start. You can get hand reared birds but I would go with parent raised if possible as they will be healthier birds in the long run. (I have 2 one hand reared and one parent raised).
Common things that you must be aware of is:
Teflon/non stick cookware is harmful to birds (toxic), if you use them the fumes can kill your bird. It's best to have all stainless steel cookware.
No nail varnish, perfumes or strong fumes like scented candles, again these can kill your bird.
Avocado, garlic, onions, and various other things are all toxic to birds so don't feed those
Do NOT feed your birds an ALL SEED DIET, its not good for them. Smaller birds do well on a split of pellets, seeds, fresh fruits and veg and pulses (you can buy soaking mixes online for these). You will need to wean them off seeds as new foods are not readily accepted and it can take a LONG time to introduce them but you must do this.
Do not take your bird to a normal vet, you need an avian vet to help with your bird you need to get your bird checked at 30 days, 6 months and 1 year (obviously more if it gets sick)
Birds really do hide their illness you need to be very familiar and vigilent with watching for signs of sickness, by the time you notice its usually too late
Correct cage size, consult this forum on good size cage for your birds and the correct bar spacing. Bar spacings are very important as the incorrect bar spacing can lead to a number of injuries or escape
Birds take time to tame- unless you get hand reared your bird will take time to tame. Don't be tempted to buy an unweaned bird. The bird should be eating seeds freely and easily. It does not make them tamer by weaning yourself and its very dangerous.
Your bird cannot be near other pets for at least 30 days and should not be allowed to play with them at all really. It's very dangerous.
Do not clip your bird, keeping your bird clipped does NOT make them safer or stop them escaping. If they fly, they may be clumsy at first but its up to you to bird proof the homeby keeping blinds down to prevent banging into windows (but make sure you tuck cords away!)
Insist your bird is not clipped, if the breeder or pet store (wouldn't recommend pet store tbh), sday they won't sell the bird flighted then go elsewhere.
Ensure plenty of antural wood perches and not the silly dowel rods that come with most cages, Java wood or custom made perches and are must with a variety of textures, lengths and diameters to help the exercise oft he feet.
I think I've ocovered most of it. Oh and bird safe disifectant not household F10 is a good brand
