I remember a story about a woman telling her next door neighbour that her husband whistles back to the blackbird every evening for about 15 mins. Funnily enough, said the neighbour, my husband does the same thing.
Turns out the two husbands were whistling to each other every evening over the fence.
From early morning to late evening there is a bird that makes a repetitive sound like "tweet tweet" which continues on and on. Any ideas what type of bird this is and is it migratory.
