Seeds germinate, however seedling survival rate remains low

Many of the seeds purchased offline are germinating, however the survival rate for most of the seedlings is very low
Earlier the seeds were grown in pots in the terrace, however no seedling was growing at all, because the birds were eating all the seeds .
So for a change the pots with seeds were kept indoors and after the seedlings grew they were kept outdoors on the terrace
For example more than 100 seeds were planted, however after the seedlings grow, it appears that squirrels, birds are extremely aggressive in eating the seedlings.
It appears that the birds have a photographic memory, remember the condition of the pots and eating up almost everything
New places have to be found to grow the plants, so that they are not attacked
