Crow visiting . . .

I played the recorded sound of  crows, a few minutes later this young crow seemed to drop out of the tree above the bird bath. Had he heard the bird sounds? Or was it just a coincidence...

Cardinals visiting . . .

I wondered, if I play bird sounds (found online), will the birds respond? On my IPhone I played Cardinals singing, a minute later I heard real-life Cardinals responding; then, two Cardinals flew over my head and (see way down below) you can see one of the Cardinals sitting in a tree after I played "Cardinals, bird sounds", that's what you Google to get these sites, one in particular, "all about birds", is the site that I used. Cardinals are friendly birds and they aren't particularly shy. The first photographs below were taken when a Cardinal swooped down and sat in the bird bath. The final photos below were taken on the morning of 20 August from our dining room window.
