It seems to me that birds avoid many "hard" berries until other food is
in short supply. By hard berries I mean fruits from holly, hawthorn,
pyracantha, etc. I assume such berries are less palatable and/or less
nutritious than soft fruits.

My pyracantha never gets touched unless everything is frozen, which BTW
has not happened for a few years here on Tyneside.
