Put in a more interesting rowan if you want to feed the birds -

Rock has yellow berries that are taken in January/February.

Because they're not favoured by birds - probably not the taste, just
that their colour doesn't fit the search pattern. But it means that if
there are plenty of other berries around, they'll be taken in
preference. So if the aim is primarily bird feeding, it's probably best
to stick to the oranges and reds.
