Blackbirds will be down on the lawns when it rains listening for worms,but if you have decking you will hardly see any if you have a bird table try putting some mealworms on it.they love them. Soon come July most blackbirds will fly to woods etc as most birds go in moult this time of year. Robins and blackbirds, and wrens will usually feed on the ground or occasionly off a bird table. Woodpeckers love old rotting trees. Planting berry type plants will always attract birds, Hawthorn, Holly,pyracanthus, cherry treees ,apple etc. some birds get water from flower buds.or peck your vegtables too,I have a blackbird who likes grapes and chips. All good.
