Talking to birds

My friend Elizabeth in Detroit sent me a Canary Flute a few weeks ago. I've never seen anything like it (pic and description below).

A classic American 'Dime' toy, first made in 1954. The slide and the clever vibrating canary allow an extraordinary range of trills, warbles, toots and whistles to be blown.

I sat in my garden for a bit after I got home from work, and breathed in the fragrance of my lilac trees in bloom. The sun was dropping and made little halos of light behind the leaves of the apple tree. A blue tit was hopping around my flower beds, looking for something to eat. The birds were so lively that I decided to try out my Canary Flute. I wonder what the neighbours thought of the trilling I was producing on my flute. But I'm not kidding, I had a conflab with a blackbird in a tree next door. I'd talk, then he'd reply, then I'd answer. But after a while, he started ignoring me.

Must be something I said?
