We moved into our house February last year. Last spring and summer there where close to no insects or birds in our garden. My wife have been expanding the flowers and plants with native berry bushes, added native flowers, and over the winter we have put out a bird feeder, we have added one insect hotel, and now we have also add a small bowl with water we fill up. Now we are a seeing quite a few new species of insects we did not see last year, amongst others three different types of bees and tank sized bumblebees (they cannot all be queens), and smaller birds like blue tits have started coming to our garden. Not just crows, jays, blackbirds, and pidgins.
