Rsync errors not printed in terminal but are logged to file [duplicate]

I’m running rsync with:
1.

rsync -a --exclude cache/ src_folder/ target_folder/

and
2.

rsync -a --exclude cache/ src_folder/ target_folder/ 1>output.log 2>error.log

In 1 except for permission errors, all other rsync output is printed. In 2 the permission errors show up as expected when I log them to a file.
