You can also grow fruit in conservatories. They will, in general, be ripe sooner and thus better protected against birds eating your fruit. We can recommend for instance strawberries, kiwis, peaches, grapevines, even passiflora (edible), figs (up to 2 harvests per year), etc…
However, for these fruits the conservatory will have to be heated from December up to April.
