Hi Shiffty. I agree that you just need to wait. Birds are creatures of habit and once they get to know you're they're they'll be queueing up. My garden is still very quiet at the moment as they are all busy feeding on stuff they find naturally. I notice you havea dragon palm in the background. Those little white berries can be very popular. Mine are eaten by all the tit species and a blackcap has just returned from his travels and likes them too.
Patience and they'll be there. Oh and play some bird song out of your window. Seriously, it works
Especially with territorial robins
