I walked into my back yard this evening and heard a bird I’ve heard before (not often) but this time it’s call sounded quite urgent. I watched it flit from branch on a vine maple but it was dusk and I could not see it well. He stands out because he is small, about the size of a wren and sounds a bit like a chicken and a bit like a duck, with a loud, rapid cluck, cluck, cluck the whole time he was moving around. He just looked brown in the low light so I can’t help with appearance. Any ideas?
