Because ftpd listens on 21 directly.  Where sftp basicly does 'ssh
site.com sftp-server' (Ignoring details of subsystems to simplify stuff).
Thus it talks to ssh which then runs the sftp-server program.

Same is true for scp.

As stated:

	ssh site.com true

You should get like:

$ ssh site.org true
Enter passphrase for key '/private/home/mouring/.ssh/id_dsa':
$

the below depending on if you have public key setup or not.

$ ssh site.org true
Password:
$

If you get anything else you need to look at your shell startup scripts.
And clean them out.

This was much has already been coverted in http://www.openssh.com/faq.html#2.9
