Birds that are useful to humans could be they type we use for food such as chickens which provide eggs and meat.
They type that provide feathers for quilts such as geese.
Hawks and other raptors that catch and eat mice and rats in the fields.
Or the every day backyard birds that eat insect pests in the garden.

Birds are very helpful. They eat insects that can ruin crops. Owls eat rodents ( I would be glad to have an owl in my yard) and farmers put up owl roosting boxes to have them help them with rodent control. Birds help spread seeds and fertize plants. Predator birds kill snakes and rodents or small animals keeping the population down .
Mutation leads to variation which in some cases is helpful to insects, birds, etc (except humans) to blend in with their environments so there is better survival
monerans are helpful to humans because it is bacteria and bacteria helps humans by making milk yogurt
An aolovera plant is helpful
birds help people when people eat there meat .

This question is simple. Humans are the cause of blame. Mainly farmers. Humans not only ruined their homes and birth lands, but certain pesticides farmers use are not helpful for thease birds. this is because the birds may eat your plants and when they do the pesticides are killing them causing them to die out over time.

Ladybugs are indeed helpful to humans, because they eat aphids, and aphids are damaging to many plants that we humans like to grow.
Birds get oxygen from the atmosphere, the same as humans do.
