I'm a massive bird nerd and living out in the sticks see them ALL

I've observed, fed and loved them these past few years and I don't think there is a quick way to gain their trust. As you must have noticed they are most hungry at breakfast time, so perhaps try to tempt them closer with food at that time.
Blackbirds (and every other bird) absolutely love home bargains ultimate
large balls. Although I only feed them these in winter as they melt in summer and can kill the young if taken back to the nest due to clogging up their tiny beaks.
This is the best time of year to try befriend birds though as they're all desperate for food for their chicks, and the fledgelings themselves aren't yet savvy and will often be quite bold around people. I had a fledgling great tit jump into my bird food container as I was holding it ready to fill the feeders, happily munching away as I looked on

A good way of getting closer to them is a see through plastic bird feeder you stick onto your window.
I currently have a house Martin nesting above my front door and pheasants and partridges, doves, squirrels, stoats, you name it, they wander around and if I dare to step out of my front door

they think it's their area and I'm the unwanted guest!
The bats come out at night, fly around my home, I installed a bat box but unsure if they've used it. There's frog corner, a nature pond, wild flower meadow, fruit trees. Its a mini nature reserve in the middle of nature

Sorry to go off piste but nature is magical and to know others appreciate also makes me happy
